Northern Nut Growers Association Report of the Proceedings at the 41st Annual Meeting Part 29

I think our lunch is ready for us downstairs. We will come back up here at one o'clock.

(Whereupon, at 11:50 o'clock, a. m., the meeting was recessed, to reconvene at 1 o'clock of the same day.)

TUESDAY AFTERNOON SESSION

DR. MacDANIELS: Calling the afternoon session to order.

This afternoon I am going to turn the gavel over to our good friend, Spencer Chase, to carry on.

MR. CHASE: Thank you, thank you.

All of us are interested in the various experiment stations doing more work with nut trees, and we are very fortunate this afternoon in having two experiment stations represented, and we will first hear from Bill Clarke from Penn State, who will talk on, "Progress in nut culture at the Pennsylvania State College." Mr. Clark.

Progress in Nut Culture at the Pennsylvania State College

W. S. CLARKE, JR., State College, Pennsylvania

Work in nut growing at the Pennsylvania State College was formally begun in 1946, when a project on this subject was approved by the college authorities. A few acres of land were set aside for this work, and the following spring about half an acre was planted with a few nut trees of different species. At the present time an area of about twenty acres is set aside for nut plantings, although a few spots on this land are not plantable on account of rock outcrops.

We now have out in the field sixty black walnuts, all but three of them named varieties, which were received from Tennessee in 1949. Seventeen varieties are represented in this collection.

In the nursery are more than 200 seedling black walnuts. These were planted from nuts gathered from local trees in the fall of 1946. They were transplanted at the end of their first season and have remained in their present position for three years. They were planted largely for the sake of experience in handling the nuts and the young trees. Some of them have been grafted, and this year a few grafts of Thomas and Stabler were successful. On account of their size, all these trees will have to be taken out at the end of the present growing season.

About twenty Persian walnuts have been received from the United States Department of Agriculture. These are all budded trees, the buds having been taken from special selections with the best nuts from trees originally introduced from northern Europe and central Asia. Three out of four seedling Persian walnuts and one out of two j.a.panese walnuts planted in 1947 have survived and are included in our planting. One named variety of b.u.t.ternut is in our collection, and a number of seedlings in our nursery.

It has been our experience that walnut trees can be moved rather easily.

The percentage of loss in transplanting has been negligible. On account of an emergency, this spring we had to move several walnuts which were already in full leaf. Some of the leaves were trimmed off, and the trees have survived and have even made some additional growth.

On our grounds is one Chinese chestnut left from a planting of eight in 1930. It was killed back to the ground in 1934 after winter temperatures of close to 30 degrees below zero, but it has since grown up to be a tree of moderate size. It suffered considerable injury to buds and twigs in 1948 from temperatures down to 23 degrees below zero, but has since recovered. In several years it has borne a crop of burs, but no other tree is available for cross-pollination, and the nuts have seldom filled.

Twelve seedling Chinese chestnut trees from different sources have been planted, and an area of several acres has been set aside to extend the work on chestnuts.

A start has been made toward a collection of filberts. Five named varieties of European filberts were planted in 1947. All have suffered from winter injury, but only one tree has been killed outright. Very few nuts have been produced. About 25 seedlings of European filberts and 25 of the American were received from Tennessee two years ago. About 90% have survived and are growing nicely.

Several other species of nuts have been tried without success. Two trees of the red hickory were set out several years ago, but they failed to leaf out. Four young trees of the golden c.h.i.n.kapin of the Pacific Coast were planted and grew well the first summer, but all four were killed by the first freeze in the fall. About a pound of nuts of the Turkish tree hazel were planted several years ago; these failed to come up the first year. The next winter the mice and rabbits discovered them and ate up most of the planting. A few germinated, but most of these were lost in transplanting, and today only two are left of the entire lot.

MR. CHASE: Thank you, Mr. Clarke.

(Applause.)

Discussion

MR. SHERMAN: I'd like to say, just before you leave this subject, that the speaker barely mentioned the fertilization experiment that was started in Pennsylvania on black walnuts. I think the members of the nut survey stuck their necks out and got their heads. .h.i.t a little bit when we said that the black walnut as an orchard industry in Pennsylvania was sick. We hadn't been able to find crops of black walnuts. We found individual trees, but we couldn't find orchards of black walnuts, and as a result of that, this fertilization experiment was started, in a 55-acre black walnut orchard with Ohio, Stabler and Thomas varieties.

The owner, Truman Jones, said, "I don't care what you do with the Stablers, you can't hurt them, anyway; they are no good to begin with."

But this orchard, evidently from all outward appearances, has been growing very slowly for quite a number of years. It isn't the size it should be, and we think the main trouble there is lack of fertility, and that's the reason why this fertilization experiment was started.

It's quite an ambitious experiment. It takes in about 93 trees in the center of a 55-acre planting of black walnuts. They haven't had a crop, I think, for five or six or seven years. They don't have a crop this year, but we are hoping that some of them next year will have a crop, but if not then the year following.

They are asking about the cultivation. There has been no cultivation there in the orchard for a number of years. It's down in a pretty heavy bluegra.s.s sod. In a portion of that we put the disc in on the tractor and disced and redisced until we got what we thought was a pretty fair seedbed. They found that vertical profile a mixture, and we are hoping to have clover sod instead of bluegra.s.s sod. That's combined with fertility work. I won't take time to go into that, but I think this group is interested in knowing that there is quite an extensive fertility experiment on black walnuts to see why the large plantings are not producing.

I might say in this connection, Mr. Hostetter isn't here this afternoon, hasn't been here, but he has a dandy bang-up nice crop of nuts this year, and Ohio and Thomas are his main varieties.

MR. CRAIG: Did he use any fertilizers?

MR. SHERMAN: Yes, the fertilizer was disced in, and he tried to disc under that bluegra.s.s sod and get that rotting under there. There are quite a few ramifications to that program.

MR. CORSAN: Did you mention Turkish tree hazel?

MR. CLARKE: Yes, we have two trees of it left.

MR. CORSAN: It takes two years to sprout from the time you plant the seed. Have you tried the European beechnuts in your locality?

MR. CLARKE: No, we haven't.

MR. CORSAN: It will produce far more than the American beechnut and is more successful in every way. They can be gotten from Holland quite cheaply. They sell the European beech, and they are beautiful and loaded with nuts and the Europeans think far more of them than the Americans do. The cut-leaf beech is an European beech, and I have seen the tree in Southern Michigan and at the Old Soldiers' Home at Dayton, Ohio, loaded with nuts. And frequently, not just once in every 13 years, like our beechnut. And they are a bigger nut.

Nut Tree Culture in Missouri

T. J. TALBERT, University of Missouri, Columbia, Mo.

The wide interest now being shown in the planting of nut trees throughout the State emphasizes the need of information on nut culture.

Although nut trees may be grown with less care and attention than fruit trees, yet to be successful in starting plantings a knowledge of successful practices developed by the Missouri Agricultural Experiment Station at Columbia should prove of great value.

The information which follows applies particularly to the native black walnuts, b.u.t.ternuts, hardy northern pecans, hickories, c.h.i.n.kapins, and hazelnuts. All these nut plants are native to Missouri and may do well if given proper attention in the various districts of the state to which they are adapted.

NUTRITIVE VALUE OF NUTS

Nuts are now given in the diet a higher rating than ever before. This is true because recent studies in nutrition show that they supply not only the elements needed for health and growth, proteins, oils, and carbohydrates but also an abundance of vitamins A, B1, and G. In fact, the nuts compare very favorable with meats in rankings for the above vitamins. Most of the nuts are especially noteworthy in high vitamin A and B1 content. It is also believed generally that nuts contain nearly all of the mineral essentials demanded for the promotion of healthy nutrition.

Moreover, nuts are usually palatable in the raw stage and are prized most highly for dessert purposes. The black walnut is particularly outstanding because it retains its flavor after cooking. Nuts now have a very extensive use in the preparation of confectioneries, cakes, breads, and salads. They enhance the flavor of many other foods.

The value of nuts as food accessories has long been recognized. They also supply so much body fuel in so compact a form that they are particularly well suited for the use of mountain climbers, "hikers," and even soldiers engaged in long marches and maneuvers.

USES FOR NUT TREES

~As Shade Trees~--If during the past 40 or 50 years, a large portion of the shade trees planted had been nut trees like the native walnut, pecan, hickory, chestnut, and c.h.i.n.kapin of the better varieties, it is easy for anyone to see that great benefits would have resulted.
