Abstract
Summary Maize and cowpea were grown at various replacement ratios (100/0, 67/33, 50/50, 33/67 and 0/100) in field experiments. The experiments were carried out during the early growing seasons of 1977 and 1978 at Ibadan in the rainforest zone of Nigeria. A maize cultivar (FARZ 17) and three cowpea cultivars (Ife brown, New Era and TVu 4557) were used. Maize sown alone gave a greater yield than all mixtures. The yield of New Era cowpea was no less when grown in mixture with maize than when grown alone; indeed when grown in a 50/50 mixture it was significantly greater.
