stitute eleven to fifteen per cent. of entire weight, not more; as to number of rows, the evidence is not definite, but all points to the conclusion that they are increased up to a certain limit to the advantage of the ear in yield o' shelled corn; just what that limit is can not be given with accuracy, but the evidence seems to indicate that not less than sixteen rows should be required for a standard variety, and that twenty are not detrimental to good results. The size and shape of kernel are very important, but can only be given in words to this effect, that they should be of good depth and such shape as to fill the ear compactly, leaving a smooth surface, free from furrow or sulcus. Hardness of kernel can only approximately be determined by inspection, but the points are that the kernel be well glazed, well filled up at the end, the dent being simply a round dimple or slight longitudinal depression. All wrinkling of the end is to be avoided, as this indicates that the corneous matter does not each near enough to the surface. The ideal kernel that we should prefer would be wedgeshaped, presenting an almost square end to the surface of the ear. TESTS OF VARIETIES. We here present the entire tabulated results of the field tests of varieties, and also the examination for additional study. All weights, except those for yield, were made from samples after being properly dried. The critical examination and study was made from ten average ears selected from the corn as it lay in the field. All plots were planted May 19th, vegetated the 25th, all were given the same care. The season was quite favorable, and though some varieties were very late, they were well matured, and no soft corn is reported. None matured.

See descriptive notes. These varieties were of low vitality as shown by our test before planting. Only a small per cent. grew in one case. Only a few small ears, and no yield is given. The seed of all varieties was tested before planting, and the amount which vegetated corresponded, so far as observed, very closely with the germination test, but, unfortunately, complete observation on the vegetation of all varieties was overlooked until some of the plants had been removed. Otherwise this would have furnished excellent comparison of the per cent, of vegetation with the germination test. Table II, presents some important facts in regard to size and weight of ears and cobs. The length of ear is the average of the variety as grown at the Station the past season. |
