This article deals with six experiments that were conducted to evaluate nitrogen utilization in legumes and maize and to compare their nutritive value and economics with corresponding monocrop systems. Maize-soybean as well as maize and four locally grown legumes (cowpea, mung bean, groundnut, and French bean) were intercropped to identify compatible intercrop systems. It was found that, in general, the total yield of intercropped systems increased. The amount of the increase depended considerably on the nitrogen level used. It was also found that, applied nitrogen tended to increase the crude protein content of both maize and sorghum. It was also observed that regardless of nitrogen level, the intercrop system provided higher economic returns then the corresponding monocrop system.
