(Jun 1984). v. 2(1/2) p. 99-109Summary: Experiments were conducted for three years (1975-1977) at Mokwa and Omu-Aran, in the southern Guinea savanna zone of Nigeria, to evaluate the response of maize (Zea mays L.) to five rates of N (0, 50, 100, 150 and 200 kg/ha) and three plant population densities (24, 48 and 72 thousand plants/ha). 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/ha
