While the years the experiments have been running are yet too few for
any final conclusions, and the details too numerous to present in a
brief sketch here, there have nevertheless been some very interesting
results from the use of fertilizers which is readily shown by a few
lantern slides. Here is, for instance, a view of a fertilized and an
unfertilized section of one of our experiments in Georgia. The views
were obtained in the fall, and one could tell at a glance, not only that
the unfertilized trees were not as large, but also quite strikingly that
they had nearly lost all of their foliage, whereas the trees on the
fertilized section were still in full foliage, thus presenting a very
strong contrast. The effect of fertilizers on the foliage is shown also
in a series of slides of representative trees, from one of our
experiments in Louisiana, likewise taken in the fall. The first tree had
not been fertilized, the second had been fertilized with phosphate and
the third with potash. The one fertilized with phosphate appeared
slightly larger, but it can again be observed that all three trees were,
at the time the picture was taken, nearly three-fourths defoliated. The
next two trees from the same experiment, fertilized respectively with a
nitrogenous fertilizer and with a complete fertilizer, and photographed
at the same time, show the influence of these fertilizers strikingly in
that they are still in complete foliage, as well as showing a more
vigorous growth. Three slides of fertilized and unfertilized trees from
still different experiments all show the fuller foliage and better
branching of the fertilized trees, especially those fertilized with the
nitrogenous fertilizers or the complete fertilizers.
The yields of these trees cannot here be taken up but, in general, these
fertilized trees came into bearing earlier and have yielded double and
treble the number of nuts produced by the unfertilized trees.
(In conclusion, there was shown a slide of the yield of nuts from an
experimental tract of a commercial orchard of about 20 acres, in which
the yield from a fertilized acre was compared with the yield from an
unfertilized acre. It was noted that the unfertilized acre gave a yield
of approximately two barrels, whereas the fertilized acre gave an
increase of two bushel baskets more than the unfertilized.)
Dr. W. E. Safford, Botanist, Bureau of Plant Industry, then spoke on the
Use of Nuts by the Aboriginal Americans.
DR. SAFFORD: My interest in nuts has been confined almost entirely to
those of American origin. For a good many years, I have been studying
the plants, and plant products, utilized for food, and for other
purposes, by the aboriginal Americans, before the arrival in this
hemisphere of Columbus and his companions.
