Abstract

Extensive field studies were made throughout the Prairie Provinces over a 4-year period on the effect of four agronomic practices on the protein content of hard red spring wheat. Wheat grown on fallow was usually higher in protein percentage than that grown on stubble. There was no striking difference in the protein content of wheat grown on "trash-cover" fallow and black fallow. Spraying with 2,4-D for weed control did not affect the protein percentage. The application of nitrogen either as fertilizer to the soil or as a urea spray to the plants at the flowering stage usually raised the protein content of the grain.
