The potential of maize-cowpea intercropping in low rainfall areas of Zimbabwe - 1990 - Printed

4 tables; 10 ref. Summary (En) Library, Ministry of Lands, PB 7701, Causeway, Harare - Zimbabwe

The effect of intercropping maize and cowpea on the yield of component crops and land use efficiency expressed as Land Equivalent Ratio was assessed at a low (450-650 mm) rainfall site over two seasons. Sole maize out-yielded intercropped maize by 120 700 per cent in increased competition for moisture. Cowpea grain yield was however not affected by intercropping because the crop possibly took advantage of maize (which provided physical support) to have access to sunlight. Intercropping had no effect on land use efficiency in 1988/89, a below average rainfall year, but increased land productivity by 51 per cent in 1989/90 which was an above-average rainfall season
