Abstract

Seed yield in cowpea exhibited significant and positive association with days to maturity, plant height, number of branches, clusters and pods per plant, pod length and seeds per pod. However, days to 50 per cent flowering and 100 grain weight exhibited negative association with yield. The path analysis revealed that number of primary branches per plant, days to 50 per cent flowering and pods per plant had high positive direct effect on seed yield.
