Abstract:

A field experiment aimed at investigating the response of vegetable cowpea to intra-row spacing and defoliation at 4, 6 and 8 Weeks after Sowing (WAS) was conducted in 2009 at the Plateau State College of Agriculture, Garkawa, Nigeria (Southern guinea Savannah). Treatments consisted of four intra-row spacing (20, 30, 40, 50 cm, respectively) and four defoliation levels (0, 25, 50 and 75%, respectively). These were factorially combined and laid out in a Randomized Complete Block Design with three replications. Vegetable Cowpea growth related characters (plant height, shoot fresh weight) per plant increased significantly with decreasing levels of intra-row spacing. The intra-row spacing of 20 cm yielded 5.7 g edible leaf yields per plot. Defoliation level at 25% gave 6.8 edible leaf yields. The interaction between intra-row spacing at 20 cm and defoliation level at 25% produced the highest green pod yield of 404.7 kg/ha. Based on these findings, it would be suggested that harvesting 25% leaves of vegetable cowpea at a spacing of 20 cm at 4 and 6 WAS be practiced for optimum leaf and seed production.
