THE HICKORIES
The native hickories of Missouri have been held in high esteem since early settlements were established. They are notorious on account of their slow rate of growth yet they offer greater possibilities to nut growers than is usually believed. As shade trees they have a high ranking.
Promising varieties may now be had by obtaining scions from superior bearing seedling trees and from young named and grafted trees in the nurseries of commercial concerns. Grafted trees may come into bearing in three or four years after the operation.
Perhaps as many as five species are native of Missouri. The big shellbark or kingnut is common to the south and southwest regions, but its range is not as wide as others. The shagbark which is the most valuable nut producer of all the hickories, is rather widely distributed particularly in northern and central Missouri. Numerous varieties have been described and named because of their particular merits. Shellbark nuts may be large and attractive, but are often poorly filled.
The pignut, mockernut, and bitternut have a rather general distribution especially in the central and northern parts of the state. These nuts are not considered of great value except for their hybrids with other species. Perhaps the most natural type of hybrid occurring among the hickories is crosses between the shagbark and shellbark, one of the best varieties of which is Weiker.
The pecan and shellbark hybrids include McAllister, Nussbaumer, and Rockville, while the Burton is believed to be a pecan-shagbark cross. The natural crosses of the pecan and hickory found in the wild have not been entirely satisfactory. The trees vary greatly in fruitfulness and the nuts in thickness of shells, size, shape, and kernel quality. A strong tendency to produce nuts with imperfect kernels is common among the pecan-shellbark crosses.
Local varieties selected from the wild may have merit for use in top-working hickories or pecans. The pecan is suggested because it makes a good stock for the hickories and as it grows more rapidly. Some of the best of the older named sorts for planting or for use in top-working appear to be the following: Barnes, Fairbanks, Stanley, Weiker, Kentucky, Swain, Laney, Kirtland, and Rieke.
