Abstract

Effect of three levels of phosphours [0.20 and 40 kg/ho] and two levels of molybdenum 10 and one kg/ha) on yield, production of root nodule and uptake of p were studied for two seasons in cowpea under rainfed condition. The experimental area had low available p status. Phosphorus application at 20 kg/ha had consistantly registered higher grain yield over control in both seasons whereas Mo application did not influence the grain yield Root nodule per plant and N content of the nodule did not differ significantly among p and MO levels. Cowpea crop was found to remove 12p kg/ha of which 45 per cent is utilised for grain production.. Phosphorus application had increased the available o status of the soil.
