The Oscar Clemen Stine Papers are handwritten and typed notes on wheat history, colonial wheat culture, wheat exports and imports, insects and diseases, business and wheat crops, acreage, consumption, demand, and foreign markets. Additionally, there are publications by Stine and a manuscript of his autobiography, "Reminiscences of O.C. Stine."

SynopsisSixty pounds of nitrogen applied at seeding time gave higher yield increases on irrigated wheat than other rate or time of application. Nitrogen did not affect germination, number of spikes per head and number of kernels per spike. It increased highly significantly the number of tillers and mature heads per plant, and weight of 1,000 grains. It also increased nitrogen, moisture and potash content but decreased phosphorus and dry matter percentage. Number of kernels per head and fat and ash content were not affected.

SypnosisA new approach to studying protein quality is suggested by the capability of the wheat plant to take up, translocate, and synthesize gluten protein from the urea nitrogen sprayed on the leaves. Data show the effect of time of spraying, number of sprayings, and concentration of urea on wheat yield, test weight, and protein content and quality.

SypnosisThe application of ground limestone in every instance resulted in significant increases in the yields of corn and wheat. The yields of corn and wheat following soybeans were much lower than those following the other legumes. Lespedeza compared very favorably with the clovers. The yields in all cases tended to increase throughout the duration of the experiment. Except for a decrease on the plots on which soybeans were grown for hay, soil nitrogen was maintained at, or near, the original level.

SynopsisSimulated rain removed relatively small amounts of minerals from ripe wheat and flax plants which had been grown under field conditions. On the other hand considerably greater amounts of minerals were leached, under the same conditions, from ripe wheat plants grown in the greenhouse. Pot watered, greenhouse plants showed more leachable mineral elements at the ripe stage, than foliage wetted plants, suggesting that leaching is a continuous process.
