Resumo: 	Establishment of the ideal number of plant is a crucial point for obtaining maximum profits while cropping different species together. The main objective of the study was to investigate the effect of different plant populations of maize and beans, at two nitrogen levels, on the performance of the component crops. Two maize (20,000 and 40,000 plants ha¹) and three bean (30,000; 60,000 and 90,000 plants ha¹) populations were tested in a randomized complete block design with tree replicates. Grain yields of maize and beans were affected by intercropping and the effect was more detrimental to the legume mainly at the highest maize plant population. The application of nitrogen fertilizer to maize rows mitigated intercropping effect on maize at higher population (40,000 plants ha¹) and, at lower maize plant population (20,000 plants ha¹), benefited the associated beans by increasing grain yields. Land Equivalent Ratio values for grain yields of maize and beans showed that intercropping compared to sole cropping is advantageous and best indices were obtained at a bean plant population of 60,000 plants ha¹.
