If larvae start to feed on dry or germinating wheat, they take as auch food, and a similar proportion of embryo and endosperm, at each feeding. However, they feed twice as frequently on germinating wheat than on dry wheat, and therefore consume twice as much of the former than of the latter. It is suggested that an olfactory attractant may diffuse out from germinating wheat. The larvae gained as much weight on embryo or endosperm as on whole kernels of germinating wheat. The gain in weight on each of these foods was significantly greater than on hard seeds. Forty-four percent of those provided with whole dry seeds, 22 percent with whole germinating seeds, 26 percent with endosperm and 18 percent with embryo of germinating wheat moulted during the 28-day period. No diapause occurred in larvae fed only on endosperm of germinating wheat for 80 days.

An overview of the wheat trade starting at a Kansas farm, moving through growth, harvest, processing, marketing and uses in food. The report includes a photographic step-by-step journey from field to flour to food with information on wheat production, processing, marketing, nutritional value and a history of wheat farming in Kansas.

The Canadian-American Committee has sponsored this study of North American wheat surplus problems ... It is essentially a factual report, describing the relative importance of wheat in the Canadian and U.S. economies, outlining the development of Canadian and U.S. policies affecting wheat production and marketing, and analyzing the surplus problems and their effects on Canadian-American relations.

SynopsisGreen manure crops of sweetclover, field peas, and winter rye grown during part of the fallow period had no beneficial effects on dryland wheat yields, test weight, or protein content, There was no evidence that continued use of green manures materially affected soil nitrogen or carbon content.

Effects of P source, rate of liming, and time of contact between fertilizer and soil on the availability and uptake by plants of phosphatic fertilizers applied to several Minnesota soils have been studied in greenhouse experiments. Monocalcium phosphate resulted in significantly higher yields and lower P contents of wheat than dicalcium phosphate, and was more available to both wheat and alfalfa. Alfalfa yields generally increased with an increase in the rate of liming. Liming had no apparent effect on the total P content of wheat or alfalfa, but the uptake by alfalfa of P from applied monocalcium phosphate was increased by the 4-ton per acre rate of lime application. With both phosphate sources, alfalfa yields were highest on the alkaline soils, and lowest on an acid soil. Time of phosphate application had no consistent effect on growth rate or dry matter production of oats, although yield responses to phosphate fertilization were obtained on four soils. Phosphorus content of oats was generally increased when fertilizer was applied ahead of the planting date. Availability of applied phosphate tended to decrease on two high pH soils when fertilizer was applied 20 days or more ahead of planting.
