This was again a poor year for we
had very little rain during all of August and September just when the
trees needed it most. The tree that received nothing had the best
quality of kernels and again all the trees that received potash had good
kernels.

In 1941 I grew two acres of tobacco and the following spring the stalks
were cut in one-inch pieces and put on about twenty-five trees. The
first year I could not see that it did any good but this past summer all
the kernels from these trees were just perfect. It surely is a pleasure
to crack walnuts when at least 98% of the kernels are perfect.

Lime and Fertilizers for Our Black Walnut Trees

_By SEWARD BERHOW, Iowa_

In 1941-1942-1943 black walnut crops from trees growing in timberland in
competition with other trees were nearly a total failure. The nuts were
fair in number but not filled, the kernels badly shriveled, tough,
lacking greatly in flavor and discolored. Some of these black walnut
trees have been bearing for 50 years. Are they through, due to having
used up all the soil fertility?

Wild or native black walnut trees, growing on good soil and not crowded
have done better. It looks to me as if it is time our experiment
stations, particularly those having black walnut trees on or near their
grounds should start studying the cultural requirements of nut trees in
the way of lime and fertilizer for better nuts. I have experimented by
applying lime and fertilizer to a few bearing trees with very good
results. But we need to know the proper amounts to be used for all sizes
of trees from the transplants to the bearing trees of different sizes.
Such investigations can best be conducted by our experiment stations.

There is a very substantial increased demand for grafted nut trees each
year. This is evidence that we should make a study of our nut tree
culture and care.

The Propagation of Black Walnuts Through Budding

_By STERLING SMITH, Ohio_

The propagation of black walnuts by budding has proven a highly
successful experience. By following this method over a period of several
years, under normal weather conditions, the results have been fairly
uniform.

Stocks, upon which to bud, may either be secured from private nurseries,
state forestry departments, or by planting the seed of vigorous native
nut trees. If one desires to produce his own stock, the nut seeds should
be planted soon after they are gathered. A garden nursery row makes a
d
