The primary objective of this study was to examine the performance of maize (Zea mays L. ) and beans (Phaseolus vulgaris) grown as pure stands and intercrops.
Maize was grown in combination with 75%, 50% and 25% of beans. The replacement series technique was employed to form the intercrops. When dry matter yield of intercrops were assessed in terms of land Equivalent Ratio, the best intercrop (75% maize ,25% beans) gave an advantage of 16% . The optimum plant density for intercrop was higher than that of pure stand, which suggests that interspecific competition was less than interaspecific competition.
