Summary

Physiomorphological differences between crops in binary mixtures can influence grain yield. A two year field study considered intra-row mixtures of two sorghum varieties, one short (KSV4) and one tall (Yarwasha), with cowpea at Maiduguri in Nigeria. The performance of the component crops depended largely on the relative proportion of cowpea and sorghum in the mixtures. Comparison of actual and expected land equivalent ratios suggested that mutual compensation and cooperation prevailed within mixtures in most instances. The system productivity index of mixtures where the proportion of sorghum: cowpea was 1:3 showed that their yield stability was greater than that of other sorghum-cowpea mixtures.
