Chapter IX: Section X: Amendments to By-Laws (2)

Securing new varieties of, hardy nut trees through breeding has made some progress. Most encouraging is the work of the Federal Experiment Station at Beltsville where Doctor Crane and Doctor McKay and their associates are using modern techniques in securing new varieties of hardy nut trees. Some progress in hybridization, of course, has been made, particularly with the filberts, the hybrids developed by J. F. Jones, G. L. Slate, S. H. Graham, Heben Corsan and some others, showing great improvement over previous European varieties in their adaptability to the northern United States. At the present time there are filbert varieties of hybrid origin better than those in the nursery trade which should be propagated and made available. Work with the Chinese chestnuts has also been valuable.

It is my opinion, which I believe is shared by most of those who are familiar with progress in securing new varieties, that we are not likely to find in the wild, varieties or clones which show any marked improvement over those already found and named. There is, of course, always the possibility of the "perfect nut" arising as a chance variation. The recent walnut and hickory contests, however, have been somewhat disappointing for they have not discovered any variety of black walnut better than the Thomas for instance, or a hickory much better than some of those located years ago. This does not mean that members of the Association should not keep a sharp lookout for new varieties occurring spontaneously which will be better than existing sorts. It does mean, however, that if real "breaks" are to be secured, it will be necessary to apply some of the more effective techniques which are known in the plant breeding field. Any such program is a long time project and can only be effectively attempted by experiment stations, or by some of the young men, who begin now to make crosses under the direction or at least with the advice of those who are familiar with plant breeding techniques.

Progress has been made in the Association organization. The constitution has been thoroughly overhauled and amended, particularly to provide for regional groups. Certainly such groups are to be encouraged and have done and will do much to strengthen the national organization in the various states. It is my personal opinion that these regional groups can be of particular value in working with the experiment stations and legislatures to promote the interests of the Association. The state associations should be on the alert to build on the interests of conservation departments as related to wildlife preserves and sportsmen's clubs and other agencies which put the growing of nut trees in proper perspective. I am not at all in favor of securing either federal or state support for every minor project which comes along. However, the Northern Nut Growers Association need make no apologies for its program, particularly as it is related to the conservation of our natural resources; to the promotion of better living on the farm and those values which are real and great, even though they do not show up large in dollar value of crops produced.

Unfortunately, projects in nut growing have been started in various states, particularly Ohio and Michigan only to be eliminated before they really got under way because of lack of support. Experiment station directors, if they are confronted with a shortage of funds, are likely to run the blue pencil through items which cannot be backed up with economic considerations. The approach of the Northern Nut Growers Association it seems to me should not be to seek support on an economic basis but rather on the basis of better living on the farm, improvement of gardens and farmsteads and the advantages of growing nut trees as compared with any other horticultural activity. There has been a real increase in the importance which is given to this approach in recent times and an active state association, which can keep in touch with local conditions and call on the national association for additional support, will certainly be of great assistance in the future.

I personally am not in favor of any sort of a set up by which the national association gives a kick back of national dues to a regional association. The dues are inadequate for the national association at the present time. Looking at the whole situation with some perspective, it would seem that the regional associations might contribute to the national association rather than the reverse. If the constitution and by-laws of the Association are not such as to make affiliation with the national association and the formation of regional associations easy, they can readily be changed to secure the very best pattern that can be devised.

Perhaps one of the most acute problems with which the Association is faced is the struggle to keep financially solvent. We are all aware of our changing economy, particularly the increased costs of printing and in fact of everything that our organization uses or needs, even postage. In my thinking, the finances of the Association are much the same as those of an individual, who is confronted with expenditures that exceed his income. The things that have to be done are obvious and the same in both cases. One is to spend less and the other is to secure more funds. In the judgment of your directors and executive committee, expenditures have been reduced as low as is safe in order to keep a going organization. Members join the Association for the value which they get out of it and a large part of this value is in the form of reports, newsletters, information made available and the organization of annual meetings. If these services were discontinued or curtailed, membership falls off. This has been the experience of other plant societies, of which there are many.

In my judgment retrenchment is not the answer in the present situation. Securing additional funds is the best forward-looking policy. The question comes up as to how this may be done. Experience in our Association and I believe other associations as well, has shown that $3.00 is about as far as dues can be raised. There comes a point with every society when, if the dues are increased, there is a falling off of membership, which more than offsets the gain. Other obvious procedures are: (1) increasing the number of members; (2) providing different types of memberships to encourage larger contributions; (3) gifts; and (4) special fund raising projects. Of these various ways and means, certainly increasing the number of members is by far the more promising. The overhead of the association is not increased with additional memberships anywhere near in proportion to the contributions of those members. This is particularly true for additional copies of the report and general office expense. The drive for new members under President Best's leadership has produced gratifying results and I believe if this is continued effectively through the next few years, a membership increase can be secured that will assure the Association's balancing its budget. Somewhere in the neighborhood of a thousand paid memberships would solve most of our financial difficulties. Provision is already made for different types of memberships and it is to be hoped that many who can do so will join the contributing member class at least until we are out of our present financial woods.

Other societies raise considerable revenue through special projects such as the sale of publications of one kind or another, seed distribution or slide rental. The type of material with which the Northern Nut Growers Association deals is not comparable to some of these other organizations but certainly the possibilities of revenue through special projects need to be explored.

Research with northern nut trees is exceedingly important from the standpoint of accomplishing the objectives of the Association. The matter of breeding new varieties has already been touched on. Other types of research are such that a large part must be carried on by experiment stations which have a continuing program. Much has been done in securing observational information by Association members themselves but some problems are such that they must be continued over a long period of time and set up with adequate checks and provision for securing significant data. Otherwise the results are of no real value. Granted we need all the sound observational experience that all the members can bring to our problems, there are still aspects of culture of northern nut trees that need continuing program of scientific research.

Fortunately, much of the cultural information secured with nut crops of economic value is directly applicable to northern nut trees. This is true of the work with northwestern filberts, western walnuts, southern pecans and even the tung industry. There comes a point, however, when information thus gained needs to be checked under the specific conditions where the crops are grown and very little research has been done in the northern states where the hardy nuts are important.

Of special importance to the northern nut growers is the control of diseases and insects. At the present time the bunch disease of walnuts is becoming increasingly more troublesome and very little is known as to how this is spread or how it may be controlled. In my own filbert planting, the hazel bud mite during past years has made the crop practically a failure. Little apparently is known as to the life history of this insect or when miticides might be applied. Examples such as the bunch disease and mite damage are multiplied many times with other diseases of local or regional importance. In my thinking our best hope for getting something done is to encourage the Departments of Entomology and Plant Pathology in the experiment stations to take up these disease and insect problems, which might be attacked by graduate students as thesis subjects, even though the economic importance is not great.

As I see the situation of the Association, there is need for its members to produce more nuts of better quality. Nothing intrigues the interest of potential members as much as actually seeing and tasting locally grown samples of nuts of superior varieties. On several occasions I have tried to assemble collections of nuts for exhibit or to buy them for one purpose or another and found great difficulty in finding sources of supply. This was particularly true in the fall of 1951 when we were trying to assemble nuts for "The Things of Science" project. We wanted very much to secure Carpathian walnuts that could be sent out and used for seed purposes. There was no source to which we could turn. In several possible sources of supply, husk maggots had so infested the crop that the nuts were discolored and unattractive. It might have been possible to secure enough black walnuts to include in the kit but the problem of state quarantines against the bunch disease could not be easily adjusted.

Finally I believe the Northern Nut Growers Association is doing a very significant work. Our emphasis at the present time at least might very well be on nut growing as a hobby and for conservation, for better shade trees and for better living on the farms and homesteads rather than to emphasize the commercial angles. This will come in time if it can really be demonstrated that growing northern nut trees is a profitable venture. In these days of job specialization everyone needs a hobby and an outlet for special interests. I know of few other fields of endeavor for those who like growing things than the rewards that are to be found in the growing of hardy nut trees.

MONDAY AFTERNOON SESSION

The Monday afternoon session was convened at one o'clock p.m.

PRESIDENT MacDANIELS: The afternoon session will please be in order.

The first paper this afternoon will be, "The Future of Your Nut Planting," Mr. W. F. Sonnemann, Vandalia, Illinois.

The Future of Your Nut Planting

W. F. SONNEMANN, _Vandalia, Ill._

Ladies and gentlemen, it is a great pleasure to appear before the Northern Nut Growers Association. I am just a sprout as far as nut growing is concerned, when we consider the age of some of our old hickory nut trees.

About 25 years ago, I became interested in nut growing and, in particular, the river-bottom hickory nut tree. Then we had so many nut trees growing in the bottom that we never thought of trying to plant a tree or look after one. People could gather all the nuts they wanted and often the trees were cut just to get the nuts. They'd lay a stick of dynamite at the base of the tree to shake the nuts off.

After a few years of that, I thought we might do something to save the nut trees for the future generations. That's when I first started to plant some nuts. Incidentally, I made a big mistake, by not joining the Northern Nut Growers Association.

Naturally, I wanted the largest pecan I could find. I went to the St. Louis market and bought and planted nice Papershell pecans--very nice pecans, but the trees do not mature their crop. Mr. McDaniel and I tried to top-work them, but that's a big job. Had I joined the Northern Nut Growers Association, I could have avoided a lot of those mistakes.

There are some things that I found out in practicing law that can very well apply to nut growing. If you will pardon the reference to personal experience, I can bring forth to you about four situations. One, a good, close friend of mine had a vacant lot close to his home. He had been planting nut trees and papaw trees and persimmon trees for years. On this vacant lot he had a 25-year-old Busch walnut growing back on the alley, on the lawn was a beautiful Japanese flowering cherry, and there were two pecan trees in the yard proper. He sold the lot to a neighbor whose wife was just crazy about flowers, little dreaming that those trees would ever be cut down. I don't believe the ink of the recorder had been cooled or dried before that English walnut was cut down, the Japanese cherry grubbed out of the front lawn, and one of the pecan trees was cut. It just about broke the old owner's heart, and all he could say was, "I am just disappointed in my neighbors." And now there is a house being erected there, and the pecan tree that was 12 inches in diameter was cut. That could have been prevented, had this man given thought to the future.

Another man, named Hagen, who was instrumental in getting me interested in nut growing, had a nice group of river-bottom shellbark trees growing in his field. One of these has been propagated and named the Hagen, and although it isn't a good cracking quality, it's a very large nut.

A pipe line was laid close to that field, and this man had the fore-*sight to put a clause in this pipe-line right of way which gave him the protection of collecting adequate damages for the destruction of the trees. Didn't even need a lawyer, which is something bad for the law business. It is a suggestion, that when a pipe line, or telephone company is buying a right of way, it is possible to protect your interests in valuable trees.

Another instance of protecting nut trees was when the new U. S. Highway 40 was built across Illinois. I had the job of condemning the right of way and when the engineer and I were out walking over it we noticed a fine group of hickory nut trees on the hillside. I remarked what a nice group of trees it was. He said, "Yes, that's going to be a borrow pit up there." I said, "You mean they are going to destroy those trees?" He said, "Yes, dirt from this borrow pit will make the fill across this bottom."

I said, "Why can't we get the dirt somewhere else? Dirt is dirt."

And the engineer said, "Well, that's the plans." We had a little contrariness there, and I had to threaten to drop the case as far as that tract of land was concerned. If you fight long enough and hard enough in such cases you may find some other person who is interested in nut trees. We did; we found an engineer higher up, and that group of hickory trees is now a picnic area. They used a borrow pit somewhere else, and it gives me a great pleasure to drive past that group of hickory trees and see them still standing there. In the fall of the year you'd be surprised at the number of people at that picnic area, and they keep those hickory nuts picked up clean as fast as they fall.

In our county hospital just started they happened to select a piece of ground I own an interest in for a county hospital. On that are some good hickory nut trees. I told them they'd never get the land until they made some arrangements in regard to those nut trees. The engineer that designed that hospital must have had some sense, because they are building a canopy around one of the trees adjacent to that hospital, and have arranged to cut only one scrub oak. The other trees will be mentioned in the deed with restrictive covenants to protect them.

If you sign anything a company gives you, you are liable to have anything cut on your land. Remember the saying that "the big print gives it to you and the fine print takes it away." And it's the fine print you want to watch in all your right of ways or in your condemnation proceedings.

I know a man who had almost 160 acres of river-bottom hickories. During his lifetime he was very careful about those trees. He would cut the brush around the trees and harvest those hickory nuts as if it was a crop of corn or beans. Upon his death his children were scattered over the various states. They didn't care anything for this hickory grove. It's been cut. Now there is a bulldozer in there trying to clean out those hickory stumps. They are not making much progress. All you now have in that farm is 160 acres of old tree stumps, wild honey-suckle vines, poison ivy and poison oak, and even a coon hunter gripes when he has to take his dogs through there on a coon hunt. Those heirs care nothing about it.

In selling land it doesn't make any difference whether it's a sale to a neighbor, or to a friend or a stranger, you should protect any trees that you have growing upon that land by what we term a covenant running with the land, and that means if a deed is made it will provide that certain trees shall not be cut within a certain period of time. In one case where I am forced to sell some land I am protecting the trees for 10 years.

Each of these situations requires research under your own state laws. I had hoped to be able to tell you something definite and precise as to each situation, but when I considered the membership in the Northern Nut Growers, the many states it covers and the great difference in the state laws, it's just impossible to lay your hand upon one set of facts that governs. You should consult your attorney who is dealing with your transactions and tell him specifically what you have in mind and what you want to protect. He will know whether your state recognizes covenants running with your land and what provision can be made to protect trees that you want to save or secure damages.

Remember, in any transaction, if it is not in the written instrument that you sign, it's just an oral agreement that you make on the side, and it doesn't mean a thing. It has to be in the paper that you sign.

As I mentioned briefly, in what they call "eminent domain", the state has a right to take property for public use. The only thing you can do there is just get your head square and fight, and if you are stubborn enough, you may find someone in the organization that you are dealing with who has some interest in trees. They may not be members of the Northern Nut Growers Association or any tree association, but there are some people who appreciate trees and who do realize how long it takes to have a nice pecan tree or nice hickory nut tree growing.

If they call you contrary, that you won't give in to anything, let them call you contrary, let them call you nuts, but you can protect your trees and make sure that their future is secure.

What will happen to your trees after you are dead? Each individual's situation has to be considered separately. In many states you can provide by will to whom you want your nut planting to go, or you can, by making a trust, give the trees to trustees with certain powers and duties to care for and manage them for a period of time or perpetually, depending on the laws of your state. Usually it is limited to the life of some person or 21 years. In that length of time if your heirs or the person you desire these trees to go to have not educated themselves to the value of the tree, then the planting will be lost anyway.

In all of these cases and all the transactions that you make, if you value your trees--and you surely do when you will carry water for them and plant them and dig that large hole for those roots--it is worth while to look after them during the trees' lifetime, not your own lifetime. And if you will consult with your attorney, particularly mention those trees to him and just exactly what your ideas are, I think you will be assured that you will have a future for nut trees.

PRESIDENT MacDANIELS: Thank you, Mr. Sonnemann.

Are there any questions you wish to ask on this subject. Here is a chance to get free legal advice on the spot. That's unusual.

DR. GRAVATT: There is one point I'd like to bring out, backing up what the gentleman just said. You know we introduced back in 1928 to 1936 very large numbers of Chinese and Japanese chestnuts. Most of them went out to state forestry departments and such; somewhere around a half million trees. We have had some very valuable cooperative orchard plantings, which have been lost because something happened to the man, he moved away, sold his property, or died. With these gentlemen who have passed away, experimental orchard plantings and other trees were part of their lives, but their children, or whoever inherited the property, had no interest in continuing the work.

We have had the same experience with some agricultural experiment stations where one of the horticulturists is interested in the plantings, but has moved away, and we have lost our plantings.

PRESIDENT MacDANIELS: Thank you, Dr. Gravatt. Mr. Becker, do you wish to say something about the Reed Memorial?

MR. BECKER: This is just a word of appreciation to a number of the Northern Nut Growers members who have helped out with the C. A. Reed Memorial.

When we organized the Michigan Nut Growers Association last January it was Professor O'Rourke's idea to have a memorial at Mr. Reed's home town, which is Howell, Michigan. With Mrs. Reed's approval we planned as our first project, planting a nut tree with a suitable plaque in memory of the late Dr. Reed.

As a followup, we issued a little bulletin asking for contributions toward the memorial. We sent these out to people who knew Mr. Reed, many of whom are among this group.

Response has been gratifying and we now have approximately $95 toward the tablet. On Arbor Day a Michigan variety of shagbark hickory called the Abscoda was planted at Howell on the library grounds. The services were conducted with the cooperation of the Michigan State College and the Livingston County garden group. This is a word of appreciation and also to explain what we have done. Thank you. (Applause.)

PRESIDENT MacDANIELS: We will go on to the next paper, "The Value of a Tree," Ferdinand Bolten, Linton, Indiana. Mr. Bolton. (Applause.)

MR. BOLTEN: Members of the Northern Nut Growers Association and ladies and gentlemen: I am just a farmer. I am not a speech-maker, like the lawyer here who makes his living talking. I make my living farming, and I have some ideas, views that I'd like to bring before you.

The Value of a Tree

FERD BOLTEN, _Linton, Ind._

Members of the Northern Nut Growers Association, ladies, and gentlemen. It may be a little unusual for a fruit grower and farmer to be on this program; however, I have lived a lifetime working with trees on the same farm I was born on sixty-six years ago last May. We have one hundred acres of orchard, several varieties of nut trees, including English walnut, pecans, hybrid pecans or hicans, hickories, filberts, hazelnuts, heart nuts, butternuts, black walnuts; also, persimmons, pawpaws, hybrid oaks and many of the native forest trees. In operating a farm this size, you naturally get a lot of experience and headaches. A very good friend of mine told me a joke that I think fits in with my farm very well. He said a fruit grower delivered a load of apples to the insane asylum. One of the inmates was helping unload the apples. The inmate kept talking about apples, so the grower asked him if he was ever on a fruit farm. The inmate replied that he was before he came to the asylum and, in return, asked the grower if he had ever been in the asylum. The grower replied that he had not. Then the inmate said, "Mr., I have been both places, and I can tell you something. It is a lot nicer here than it is on a fruit farm".

My subject is,

THE VALUE OF A TREE

A tree out of its natural habitat sometimes becomes worthless. As an extreme example, the orange tree in Indiana has no commercial value and the apple tree in Florida has no commercial value. Therefore, it seems that we should, in Indiana, endeavor to develop better trees in the trees which are at home here. This includes the native hickory and the black walnut, hazels, filberts and the pecans in Southern Indiana. Personally, I am spending quite a bit of time with the Crath Carpathian English or Persian Walnut. Last winter, I lost seven out of fifty trees from some cause, after they had gone through the winter of 1950 and 1951, at a temperature of nineteen below zero without injury. It may have been they were caught last fall by a hard freeze in full foliage, early before the apples were all picked; and, again, it may be blight. I hope not. But this I do know, the hickory and black walnut in their natural habitat were not injured.

I wonder why hickories are so erratic in their bearing habits. Could it be the winter rest period? For example, the peach has to have from seven hundred hours, in some varieties, to twelve hundred hours, in others, of below forty-five degrees temperature, or they will not set a good crop of fruit. The value of a variety of peach in Georgia sometimes is determined by the number of hours of rest period below forty-five degrees that the variety has to have. It has happened that the same variety of peach has produced a good crop in Northern Georgia and a poor crop in Southern Georgia. Where the winter was not as cold in Indiana we never lose crops from the lack of enough cold weather; we lose them from sub-zero temperatures. So you see, the value of a variety in Georgia is different to Indiana.

The value of a tree may be in the wood or in the food its produces, or its beauty in winter. Many a picture is taken of evergreens covered with snow. Its value may be its beauty in summer, or the coloring of its leaves in the fall. There is also a sentimental value; a limb that is just right for a child's swing, the Constitutional Elm at Corydon, or the Harrison Oak at North Bend, Ohio. They have a historical value and are visited by many people.

A man said to me some time ago, "I wonder why God made the hicans the cross between the pecans and the hickory?" There may be a valuable nut tree show up in the second or third generation of the hybrid trees when certain characteristics begin to revert to the parent trees. I have on my farm some hybrid oaks grafted, and am very anxious to see them produce acorns so I can plant them and watch the results. This hybrid originated in the Greene and Sullivan County Forest in Indiana, and is called the Carpenter Oak after Mr. Carpenter, the district forester. It is, apparently, a cross between the shingle oak and the pin oak because it is comparable with both of them.

The value of a tree is not always the one that wins first prize in the show. The best plate of nuts in the show may not be from the most valuable tree, because it may be biennial in bearing habits, it may be a shy bearer, it may be an early bloomer and subject to frost. My most productive Crath Carpathian tree is not the best walnut and would not get anywhere in the show, but it is hardy, blooms late, and is productive; so its value is in these traits. The number of chromosomes in the Crath Carpathian walnut may be different. There is quite a difference in the size of nuts produced on individual trees. This indicates that there may be a difference in chromosome count. If this is true, it will be a great help in improving the size of the nuts produced. It may be of value in pollination. The triploid apple needs to be pollinated by the diploid variety. By setting them close together, you get a much better set of fruit.

Sometimes I think trees are as temperamental as people. Some trees, especially the apple, lose their value because they are subject to certain diseases. Some are susceptible to scab, blight, codling moth, rots, blotch, and other diseases, to a point where they become worthless as commercial varieties. The honey locust has been considered one of the trees on farms to be destroyed, because it was thought to be worthless. Now, its value is being found in the correcting of sugar deficiency in dairy cattle. The pods of the honey locust are one of the best foods to correct sugar deficiency and cattle like them and eat them freely. I have on my farm a thornless honey locust that produced ten bushels of pods one year. The honey locust is also a legume and produces nitrogen which, in turn, is used by the pasture grasses and makes more pasture for the cattle.

The mulberry tree that ripens when cherries are ripe has a value in the fact that every mulberry eaten by a bird saves a cherry and the birds are valuable because they destroy insects that cause the worms in cherries.

After observing trees for years, I am convinced that there are certain strains or families of trees in the forest that have outstanding traits. Those traits in growth might be dwarfs or they may be giants; they may have short lives or long lives, like different varieties of apples. The fruit or seeds may be large or small. I believe as reforestation progresses there will be certain trees located which have value as seed trees and which will improve the forest equal to the improvement in livestock on the farms today. The razor back hog that roamed the forest is gone and has been replaced by animals much improved; yet, the forest in which it roamed is the same. Now we are turning to man made forests and a chance to improve them by selecting the more valuable trees for our source of seed. In the native hickory and black walnut, there is a great need for more interest in searching for and preserving the most valuable trees for their cracking quality, flavor, and productivity. There have been and are now, nut trees on farms that were valuable trees, but were known only to the owner and the small boys of the community. These trees should have been preserved for posterity, but many of them are lost forever.

In forestry, a tree's value may be in its ability to re-seed itself. In the kinds of pine, the Virginia pine is one of the best, and also, one of the youngest to produce seed cones. I have counted twenty-five cones on a five year old Virginia Pine tree. In forestry, the red cedar is good to re-seed itself in the area in which it grows. The maple ash, cotton wood, and poplar also grow freely from nature's seeding.

Every tree that grows has a value. The leaves help purify the air; the persimmon and the tree with a wild grapevine are food for wild life. The old hollow tree is a refuge for the coon and o'possum and other wild life. I have a hollow white oak on my farm I let stand because a family of squirrels is raised in it every year. I also have a bee tree and the bees help pollinate my fruit trees so they produce better. A world without trees would be a desolate place. The value of a park is in its trees.

I have spoken of the value of trees for the preservation of wild life, but how do trees affect the life of man and how does man affect tree life? Man is the builder or destroyer of tree life; although the tree is the oldest living thing in plant or animal life, man is master over trees. A man came into my farm office one day and said, "Everything in this room either grew from the earth or was mined from the earth." How about everything in this room? The furniture, the clothing you wear, the ring on your finger, the glass in the windows, etc.? Let us think for a minute, what are the things of the greatest value in this room? We have an organization, The Northern Nut Growers Association. It did not grow from the earth, there is knowledge of science here, there are doctors' degrees (I wish I had one), there is ambition, honesty, love, pride, and patriotism. Man's knowledge is the key. What he leaves alone or what he destroys. So the greatest value is man's knowledge. After all, the greatest values are the things that come from the minds and the hearts of men. By man's efforts, we find or develop these valuable trees.

The value of a home is increased by trees. The love of trees and the pride in owning a home is hard to separate. The privilege in America to own a home and plant a tree on your own ground is of great value. It has been said that he, who plants a tree, is truly a servant of God. I sometimes wonder if this great value of the privilege of owning a piece of ground and building a home and planting a tree is in danger of being lost under the present creeping grip of socialism and communism. This privilege of planting and owning a tree is of greater value than any tree, and we must not lose this valuable inheritance in America.

PRESIDENT MacDANIELS: Mr. Magill, are you all set with your program?

MR. MAGILL: Yes, sir. This is to be a discussion of "Methods of Getting Better Annual Crops on Black Walnut--A symposium led by W. W. Magill (Kentucky)--Discussion by a panel made up of W. G. Tatum, Spencer Chase, W. B. Ward and Mr. Schlagenbusch." Will those men come here? We will get started.

My business in life is Extension peddler down in Kentucky, working on fruits and nuts and berries, and naturally that takes me into a good many counties. We have 120, and I have been in all of them. Some places didn't have anything, so no reason to go back. But I pick up a lot of conversation, people give you ideas and things to think about.

We were talking about the conditions of the world--everybody's got a good job and plenty of money and biggest incomes that the country has ever known. That's true, but if you take down in the hills and hollows into some places that I go and you take the financial status of certain of those families, it's not measured in thousands of dollars, some cases not hardly measured in hundreds of dollars. It's measured in terms of gratuities and things to eat and not measured by greenbacks, and the families don't pay income tax.

Last fall I was out on a farm in the foothills some 70 miles from Lexington, in a place that most of you folks wouldn't want to live in and call home, a little farm, probably 16 acres, with a widow lady probably 65 years old, living there with her daughter. And among other things, she said, "Mr. Magill, I understand that you are supposed to know something about nuts. See that tree standing right out there?" She says, "I will give you a $20 bill if you will tell me how to make that nut tree bear annual crops."

Well, I was a little bit surprised. I listened, and I got to asking her questions. Some member of the family had gone to Chicago years ago, and she knew about all the black walnut packing firms in Kentucky. This relative had worked in the market, and had indicated she could get a dollar a pound for all the nut meats she would pick out and send to this relative in Chicago. And that nut tree meant about 30 to 35 dollars a year when it had a crop but only bore every other year.

Well, that drove home just a little more to me than ever before the question of why certain nut trees bore and others didn't bear. To that lady there it meant $30 the year it bore and no income from that tree on the year it didn't bear. And she stood there beside the home and pointed out other trees that bore regularly. And she said, "Why do they bear regular crops and this good tree that makes so many fine, big kernels bears every other year?" That's a challenge I am throwing out to this audience today to all the members on this panel.

I am hoping that Pappy Ward or Friend Chase will answer that question completely. The thing I have in mind, is that in a group like we have here today, as many nuts as we have got here, if we think about this question and talk to the folks back home, I believe in a year or two we can have worked out and have printed in the records of the report some pretty reasonable answers as to why nut trees don't bear, or why they bear heavy crops on certain years and are off certain years.

Mr. Ward, I know you have observed this over a period of years. What, in your opinion, is the one factor that is more responsible for this alternate bearing of black walnuts?

Why Black Walnuts Fail to Bear Satisfactory Crops

W. B. WARD, _Department of Horticulture, Purdue University, Lafayette, Ind._

When man or nature, and sometimes both, change the natural habits of a tree, most anything can happen. There are years when the black walnut sets very few fruits either on the seedling trees or trees of named varieties. Some few trees have alternate years of production, while other trees bear annually and some not at all. Good results and good crops may be expected only when several factors are normal and conditions favorable. After twenty years of keeping records and observations on nut trees and through correspondence with other growers, I consider the main reason for crop failure or light production to be climatic conditions and the weather for an entire year.

The black walnut produces a pistillate flower at the end of the present season's growth. The staminate flowers, or catkins, come from last year's wood. Good growing conditions are desirable for wood growth and fruit bud formation and any retarding of growth the previous season means little or no production. Winter injury to wood and bud, diseases or insects attacking the foliage, soil moisture, and summer temperatures will lower tree vitality. There are times when strong vigorous trees fail to fruit which could be due to a high or low carbohydrate-nitrogen balance. Soil type, plant food, age of tree, and location will have some influence on annual or even biennial production but yet are not the all important reasons for light crops.

The pollen of the black walnut is mostly wind borne as few insects ever visit the flowers and pollination is dependent on wind borne pollen. Trees planted in groups and close together are generally more productive than trees planted in orchard rows even as close as 40' by 40'. When the weather is cold and rainy during bloom, one should not expect much of a crop.

The staminate flowers opened early in Indiana the years of 1950, 1951, and 1952. The weather was more or less ideal during the time the catkins had elongated and about ready to shed pollen. This warm spell was followed by a fairly cool weather and considerable rain, which delayed the opening of the pistillate flowers, consequently the pollen dried and was lost before the pistil was receptive.

The few walnut trees in the University plantation have always had the best of care. The trees have been mulched, fertilized (both through root and leaf feedings), sprayed, cultivated and seeded to grass with the grass clipped. The trees are some distance away from other seedling walnuts and a bit off the beaten path of the right direction of the spring winds. The varieties are Ohio, Stambaugh, Stabler, Rohwer, and Thomas. When the spring weather is balmy at flowering time, the trees bear a respectable crop but let the weather change to cool and moist and then that is the time one begins to think about calling up the sawmill to see if there is any need for some good walnut logs.

MR. MAGILL: That's a mighty good discussion. I see Mr. Ward has been observing walnut trees closer than I assumed he had.

Mr. Chase, I know you have seen a lot of things in Tennessee that you are not going to tell us about, but I suggest that you discuss some of the things you have observed about walnut trees bearing anywhere.

MR. CHASE: Alternate bearing has been a problem with fruits and nuts since time immemorial. I know a tremendous amount of work has been done with the apple, which has a definite biennial bearing habit. There have been all sorts of things tried to make it bear annual crops, and as far as I know, there has not been anything effective developed along that line. Of course, there are varieties of apples that tend to bear annual crops.

As Mr. Ward brought out--he took all my thunder, so I don't have much to say--a tree may set a heavy crop of nuts one year because frost or poor pollination the year before destroyed the crop so that a large amount of carbohydrates were built up in the tree. Now, the tree in producing a heavy crop of well filled nuts utilizes every bit of carbohydrates it has stored and can manufacture. While it is doing this the terminal bud is being formed for next year's crop, and if there isn't a sufficient amount of carbohydrates in the tree at that critical period, there is not likely to be a flower bud formed.

This is not limited just to walnuts, but occurs with nearly all fruits and nuts, with the possible exception of the chestnut.

We made a study which was reported in the 1946 report by Mr. Zarger in which he reported the bearing habits of some 135 trees over a 10-year period, and there were definite bearing cycles, or bearing habits. It was not always an on year followed by an off year, but possibly two years in a row, then nothing. There were some trees that went three years without a crop, then a crop. Very few, however, had annual crops, and the annual crops were heavy or moderately heavy, followed by what we consider a light crop.

These trees were scattered through seven states and, of course, conditions were not the same. They were all seedling trees, but careful records were kept on the bearing habits. There was a group of trees that could not be classified into any definite bearing habit. In those instances we suspected unfavorable weather at pollination time, but as a general rule, in our section I don't believe we are concerned with that factor.

The Thomas, which we can watch carefully in a nearby orchard, is definitely on one year and off the next. Quite a few are on one year and off two years. We haven't found any way to make that an annual crop, because when it sets a crop, it sets a bumper crop, and there is simply not enough food in the tree to set a sufficient number of fruit buds for the following year's crop. I am sure that a lot of you folks have observed this, and I think, Mr. Magill, that you might sound out some of them.

MR. MAGILL: Going back to an observation I made as a kid, money didn't grow in bushes around our place, and back in those days you could go out and kill ten rabbits and sell them for 8 cents apiece, and if you only used 4 cents apiece for ammunition, you have made 40 cents off of the deal and had $20 worth of fun, and that was a good day's work. You remember those days, Pappy? Back in those same times, I used to get money out of hauling black walnuts to an old corn sheller and having people who didn't have an interest in the corn sheller sell them for 50 cents a bushel. That was also pin money. Come in mighty useful.

We had a certain group of trees on the farm I was raised on that bore every other year, and I can think of two fields where we rearranged the fences in such a way as to make pasture fields out of them, and two of those trees were where 15 or 20 cattle pastured. These were the only shade trees, and naturally they manured those trees. And I recall for a few years I was getting annual crops from them. Apparently they got something supplied by cattle that they didn't have otherwise. Others in the foothills of Kentucky, have come to the same conclusion.

I know a man who has pecan holdings in Alabama. He told me up to the time he got the farm the trees had a few blooms but wouldn't set pecans. He applied 15 mineral elements and claims to have got results from it. I have talked to at least three people in my travelling around who tried the same treatment on pecans, one in Georgia, one in Alabama and one in Mississippi. They reported that they had improved yield on pecans by using complete mineral fertilizer. That's in addition to nitrogen, phosphorus and potassium.

I am foolish enough to think that that nice, young orchard of Mrs. Weber's would make an excellent place to try it. I understand that the trees are not behaving as well as they should. I'd like for Ford Wilkinson to be made chairman of a committee to see that they are fertilized according to some kind of a schedule that could be worked out and do some observing. That is one of the few places I know of in the several states that would be as adequately laid out. I'd like to see a complete fertilizer including nine or ten mineral elements used.

I don't mean spend a lot of money, but you can do a lot of observing for relatively few dollars. I just throw that out as a hint.

I would like to open up this discussion. Mr. Bolten talked a while ago about things he was growing out of the ground, or out of minerals. Everything comes from the ground, and I reckon you'd say this Northern Nut Growers Association is a little like Topsy, it just developed, as the fellow about the weeds. He said they weren't created, they just come all at once. Now I believe that out of this Northern Nut Growers assembly here that we have got some keen observers that might have something on their minds they want to tell us about. Who wants to speak first?

MR. CALDWELL: This is just an observation I am throwing out for the benefit of those who are here. I spent some time in China, and I was interested in the fact that their walnuts there produced yearly crops. In trying to find out why they produced yearly crops, I also discovered that their persimmons, their plums and their peaches did the same thing. The reason for that apparently goes back to their mythology. They believe in signs and doing certain things according to certain seasons of the year, and one of the things that they did was to gather together in the dark of the moon on one particular night at a certain time and beat the living daylights out of these trees with big bamboo clubs. I wouldn't suggest that people here do that, but it's been known to foresters quite a while that by transplanting or severely pruning or girdling trees that you could produce fruits on these trees the following year. Apparently the Chinese so injured the cambium during the severe beating that they have caused that wound stimulus to induce the formation of flower buds for the following year. By so doing in their English or Persian walnuts they did have yearly crops. I have seen this myself, and I checked back to see why. Perhaps they could explain it. The only explanation we made was not fertilizing, but in the wounding of the cambium. Now, perhaps there could be something done of that nature for walnuts, but I wouldn't suggest getting around and beating the trees up.

MR. MAGILL: In that connection, one man in Kentucky got the same answer. He said about five years ago a cyclone came through there and blew the chimney off the house and uprooted a number of apple trees and leaned over three walnut trees, and he said they have borne five crops in succession. Now, this is the same story that you have got there.

MR. STOKE: I'd just like to remark that I think that's a sort of negative approach. I noticed a boy who had an apple tree that was about to die. He girdled it and got a tremendous crop of blossom. You probably have secured the same results. That is one of Nature's ways to perpetuate itself. But I think there a constructive angle in those trees that respond to nitrogenous fertilizer or manure. I believe the secret, if there is a secret, is that a tree in bearing a crop exhausts itself more or less. It recuperates the following year and then is ready to bear another crop. And the way to meet that situation is to fertilize heavily, especially with nitrogen, the season of the heavy crop so that you will have not only enough leaf growth to produce that crop, but to build up nutrients the following year. I believe that will help break the cycle and establish more regularity.

Some trees do that themselves; that is, they will bear a moderate crop every year. I have the Land walnut at home. It bears every year. Certain chestnuts will bear every year, not excessive crops, but Hobson bears a pretty good crop every year. I believe the secret of breaking that on-and-off cycle is to fertilize heavily the year of production not the year of non-production. If you apply nitrogen on the off year you produce perhaps an excess of wood growth that year and overbearing the following year.

MR. MAGILL: Referring to apples, any of you apple growers well know that the Golden Delicious and York Imperial grow crops in alternate years. Now, you come along with hormone sprays and take half or two-thirds of the young fruits off soon after the trees blossom and throw them into regular production. That's the same thing that you are talking about, Mr. Stoke. I never heard of anybody thinning walnuts. I don't know whether they do or not. A lot of things I don't know, but I don't know of anybody ever thinning walnuts, except squirrels.
