_Bearing Habits of Wild Black Walnut_--Looking forward to a fuller
utilization of the wild black walnut crop, the bearing habits of the
black walnut tree is being investigated. Four-year records are now
available on tree growth, nut yield, and nut quality of sample trees
located throughout the Tennessee Valley. For 121 trees, with a range in
diameter from 4 to 28 inches total dry nut yield, in pounds, averaged as
follows: 1940, 31; 1941, 24; 1942, 38; 1943, 29. There is some evidence
of alternate bearing, with a heavy crop followed by a very light crop.
How much larger nut crop a larger tree is expected to bear was found to
increase on an average trend from 0 pounds of filled nuts for a tree of
4-inch diameter to 65 pounds for a 24-inch tree. Judged on the basis of
nut quality, only one of the sample trees compared favorably with
standard propagated varieties of black walnut. Filled nuts on the
average, amounted to 83 percent of total nut crop weight, and had a
total kernel percentage of 21. Recovery of marketable kernels averaged
17 percent of total nut weight. In order to learn still more about the
bearing habits of the black walnut, records on all sample trees will be
carried on for two more years.
_Macedonia Black Walnut_--A sample of black walnuts from a tree growing
on the home place of Mr. N. U. Turpen at the Macedonia Community at
Clarksville, Georgia, were sent to us for evaluation in 1939. The nuts
were thought to be two years old--from the 1937 crop. When tested, the
kernel content averaged about 40 percent--the highest on record for a
black walnut. The tree, supposed to be the one which bore the nuts we
tested, had not borne any appreciable amount since 1937. Since the tree
yielded good crops in 1942 and 1943, we are now in a position to report
further on the Macedonia walnut. Based on cracking tests of nut samples,
the average nut weight and kernel percentage were 16.8 grams and 28
percent in 1942; and 16.4 grams and 29 percent in 1943. It is apparent
that the Macedonia black walnut has not exhibited those exceptional
characteristics of thinness of shell and high kernel percent which were
found in the original sample tested.
