Agriculture -- New York (State). 1708 Report of Farmers' Institutes in the !N^orth Atlantic States; the sweet corn of our gardens which has sweet, tender, wrinkled kernels hecause it stores its food supply as glucose rather than starch, and the popcorn with its intensely hard kernels dear to the heart of the small boy. There are the four types in cultiva- tion, but the different varieties vary through a wonderful range of size and season of maturity. Corn is especially interesting from the standpoint of the plant breeder because it is a plastic plant; namely, it adapts itself very rapidly to changed Fig. 120. Eight-Eowed Yellow Flint Corx CLIMATIC requirements So far as climatic requirements of corn are concenied, two fundamental facts are to be noted: First, that corn is by origin a sub-tropical plant reach- ing its best development only with high summer temperatures; secondly, that it requires a rather abundant sunnner rainfall. It has been stated that the optimum or best temperature for corn growth is about 93 Fahrenheit — a temperature reached on only a very few days during the summer. New York State lies north of the real corn belt, and on some of the highest lands of the state it seems probable that it is wiser to put the main effort of the farm on the production of grass rather than corn. Corn can use a great deal of water, and during nor- mal seasons the crop generally suffers at some period. We should raise better corn if we could have not less than fourteen inches of rainfall during the three midsummer months. This is a matter beyond control except so far as the deficiency can be helped out by proper soil preparation and cultural methods. The value of the corn crop is far and away the greatest of any of our cereals, averaging m(»re than two and one-half billions bushels yearly, or more than four times all our wheat, three and one-half times our oats, and in value about twice all our ha
