Abstract
Eleven early maturing varieties of cowpea obtained from IITA Ibadan were planted in a randomized complete block design with three replications in the Biological garden of the
University of Ilorin permanent site .Growth and yield parameters such as number of leaves per plant, plant height at maturity, number of days to 50% flowering , days to pod maturity and
grain yield were evaluated. The result showed that IT 98K-131-2 produced highest number of leaves and this could be recommended as fodder for livestock while IT 97K-499-35 was found to have the highest yield in terms of seeds as compared to other varieties after the evaluation of growth and yield parameters. Variety IT 00K-961-5 had the tallest height at maturity while variety IT 98K-205-8 had the least height .Most of the varieties flowered between 40-42 days after planting. Early maturing varieties took between 60-70 days to mature.
