The plant type is erect with a ton- dency for lower branches for spreading. The seeds are greyish brown on cooking. Under rainted conditions, on an average the grain yield of 916 kg/ha is obtained registering an yield increase of 20.2. 50.4 and 17.7 per cent over the ruling varieties Co 3. C. 152 and Co. 2 respectively. Under irrigated conditions. Co. 4. Cowpea has recorded a mean grain yield of 1572 kg/ha registering increased grain yield of 32.7, 37.5, and 49.9 per cent over Co. 3.
