Maximum grain yield was obtained with 120 kg N/ha and a population density of 50,000 plants/ha. There was a significant nitrogen plant density interaction at both locations. Nitrogen-use efficiency, calculated as kg of grain per kg of fertilizer N, was highest at a population density of 50,000 and lowest at 24,000 plants/haCollection: AGRIS Collection
