Abstract
The efficacy of irradiated carrageenan as plant growth promoter in cowpea and bush sitao was determined using Mabunyi and PSB Bs3 varieties. The highest plant height in cowpea was obtained in RF + IC and ½ RF + IC treatments while for bush sitao, all RF- and IC- treated plants were taller than the control. For commercial crop production parameters, only weight and yield of fresh pods in cowpea showed significant differences among treatments. Cowpea pods were heavier in RF + IC and 1/2 RF + IC treated plants than in other treatments. Highest fresh yield in cowpea was obtained in ½ RF + IC treated plants. Seed diameter and 100-seed weight for cowpea and gross and net weight of harvested seeds and 100-seed weight for bush sitao were the seed production parameters that showed significant differences among treatments. Application of 1/2 RF + IC improved the gross and net weight of harvested seeds of bush sitao and 100-seed weight of both crops. Seed diameter of cowpea was highest in all treatments with IC. This study recommends the use of IC in cowpea and bush sitao crop and seed production in combination with the RF.
