Third report on the chemical composition and physical properties of American cereals, wheat, oats, barley and rye (U. S. Dept. of agriculture. Division of chemistry. Bulletin)

Colorado were still characterized by the source of the seed. Average composition of crop from seed from various sources. These wheats were the richest in albuminoids of any that had been examined up to that time in this country. Since then the hard spring wheats of the Northwest have been found to be more nitrogenous, but not comparable in their size or yield. The second year, twelve varieties, grown from seed supplied by the Department of A griculture, were analyzed. After one year, that is to say, the first years growth in Colorado, they were found to have all increased in size, and instead of an average weight of 3.402 grams per hundred grains, they weighed 4.299 grams. As regards the percentage of albuminoids, where the seed wheat was low in nitrogen there was a gain, but as half of the varieties contained originally more albuminoids than the average Colorado grain, there was a drop in six of the twelve specimens toward the average. For example, a seed having 16.11 per cent, of albuminoids, the crop fell to 14 91 per cent., while one having only 9.65 rose to 12.15 per cent. From these facts, and the analyses of the previous year, the conclusion was drawn that the conditions in Colorado were suited to the production of a grain containing about 13 per cent, of albuminoids. This was undoubtedly the case at the time. In the two following years, however, these conditions have been somewhat modified. In the third year, 57 varieties were examined, 28 of which had been analyzed before in 1881. A loss of albuminoids occurred in all but 4cases, and a loss of weight in all. The average for the year was Weight of 100 grains. Grams 3.941.
