Abstract

Field investigation was carried out to study the influence of different sources of nutrients on seed production in vegetable cowpea (Vigna unguiculata ssp. sesquipedalis) during 2010-11 in Randomized Block Design, with twelve combinations of nutrient sources. Results showed significant variation in seed yield potential in the crop. Highest seed yield (435.97kg ha^-1) was recorded in the treatment where recommended NPK dose for the seed crop was applied along with vermicompost at 50 per cent nitrogen substitution. Yield attributes were found non-significant, but had a positive influence on seed yield. Germination percentage and 100-seed weight was significantly higher in treatments receiving a combination of vermicompost and poultry manure. Benefit:Cost analysis revealed that 50 per cent N substitution with vermicompost and 25% N with poultry manure were the most profitable in cowpea seed production.
