Abstract
Yield potential of twelve medium maturity vegetable pigeon pea (Cajanus cajan) cultivars was evaluated at two locations, Kiboko and Kambi ya Mawe in eastern Kenya during 2012 and 2013 cropping years. Pigeon pea pod numbers, seeds per pod, seed mass; grain yield and shelling percentage were quantified in three replicated plots, arranged in a randomized complete block design. Significant differences (P<0.05) in grain yield (Kg/ha) was recorded among cultivars and cropping seasons. Yield of vegetable pigeon pea cultivars varied between locations as grain weight, pod length and seed mass were greater at Kiboko than Kambi ya Mawe location. Similarly, signifi-cant (P<0.05) and positive correlation coefficients between grain yield and pods plus grain as well as shelling per-centage were recorded, indicating that this is an important variable for cultivar selection in vegetable pigeon pea. The cultivars ICEAP 00068, ICEAP 00540, ICEAP 00554, ICEAP 00902, and MZ 2/9 showed high yield potential under rain-fed conditions, while ICEAP 00902, ICEAP 00068, ICEAP 00557, ICEAP 00554 and MTHAWAJUNI had good yield response when supplemental water was applied. Under both rain-fed and supplementary water ap-plications, the yield response of the cultivars KAT 60/8, ICEAP 00068, ICEAP 00554, and ICEAP 00902 ranged from 1,315 to 4,702 Kg per hectare. Selective deployment of cultivars can greatly improve its productivity and utilization in the dry agricultural regions.
