The differential ability of strains of a crop species to absorb and utilize nitrogen has important implications in the development of new field crop varieties. This fact becomes more important with the increased need for nitrogen fertilization that is necessary to maintain and improve the yields of crops. Varieties of crops which produce relatively high yields when grown on soils with limited amounts of available nitrogen will undoubtedly be more popular in the future. Harvey (6) found that some com inbreds were more efficient than others in utilizing soil nitrogen. This characteristic proved to be inherited in crosses between good and poor nitrogen utilizing lines. This report is a summary of greenhouse and field experiments conducted to determine the total nitrogen accumulation in a number of oat varieties at different stages of growth and at several levels of nitrogen fertilization. In some experiments the nitrogen was measured in both the vegetative tissue and the grain; in others only the grain was analyzed.
