The per cent of kernel in the nuts as recorded in table No. 4 is
interesting. The Burson, which was the smallest nut in 1947, had the
highest per cent of kernel and also had the highest total kernel content
of any sample in that year. Evidently the per cent of kernel is higher
in well-filled nuts and this is largely determined by the weather and
available food supply late in the season.
A comparison of the numerical score of the various nuts, figured out
according to the T.V.A. score system, is given in Table No. 5. By this
system, no variety had a consistent high score, but each varied greatly
from year to year.
The nut characters studied so far in charts 1 to 5 inclusive have varied
so much from year to year that any judgment based on these characters
for any one year could not be relied upon.
What characteristic of a black walnut, then, can be used in evaluating
it? In table No. 6 the percentage of the total kernel that is recovered
at first cracking is given. Oliver and Penn show considerable
consistency in that they remain above 91 per cent in all samples, but
look at the Kuhn. It was perfect in 1950 but in 1948 only 65 per cent of
the kernel was recoverable in the first cracking and Duke was nearly as
bad, varying from 69 to 98 per cent recovery.
After careful study of these six charts, I am sure you will have to
admit that any judgment of a black walnut variety based on these
characters only is none too dependable.
These are the nut characters that we have been using in our contest!
Some further method of evaluation is needed! Individual nut characters
alone are not enough. A good farmer is concerned in quality of his
produce but quantity is of more importance for financial success. The
Elberta peach well illustrates this. There are many peaches of better
quality, but the Elberta peach is a prolific producer and this is one
reason more Elberta peaches are raised than any other variety. Quality
without quantity means little.
With this in mind, the $50.00 sweepstakes prize was offered for the tree
with the best five-year record. The judges interpreted this to mean the
most pound of kernels produced that were recovered on first crack. Going
back over the records, we find some trees have been much more productive
than others.
At first it would seem unfair to compare the crop from trees of
different size and age, but this time luck was with the judges. Take a
look at Table No. 7 which gives the ages and sizes of the trees. There
is not too much difference in size or age to make reasonable comparisons
possible. However, it should be clearly understood that only trees of
the same age growing in the same orchard and receiving the same care can
be accurately compared. The trees we are dealing with were in different
localities, with vast differences in soil conditions, air drainage,
climate, etc.
