Cowpea at five plant population densities of 90000, 50000, 60000, 40000 and 30000 plants/ha was intercropped with maize at the standard population of 44 000 plants/ha. The control treatments were solecropping maize and solecropping cowpea at 44000 and 90000 plants/ha respectively. Grain yield of maize in solecropping was 40% greater than that from intercropping. Grain yield of cowpea from solecropping was 135% greater than that from intercropping. The best intercropping treatment was at the 50000 plants/ha plant population of cowpea. This treatment had the highest total land equivalent ratio which was 25% greater than that from solecropping, and a total monetary value which was second best from that of solecropping maize. This study will be continued for another four years before final conclusions are made.Collection: CIMMYT Publications Collection
