Abstract


A field experiment was carried out for two years during kharif season of 1985-86 and 1986-87 under rainfed conditions on shallow black soil of Agricultural Research Station, Bijapur. The highest grain yield was recorded with genotype Madhu (574 kg/ha), due to more number of pods and grain weight per plant as compared to BGM-1 and HPK-2. Appli­cation of 25 kg nitrogen / ha produced significantly higher grain yield (543 kg/ha) as com­pared to no nitrogen and the yield increase was to the extent of 61 percent. Similarly significant increase in grain yield was obtained with application of 40 kg P2 0s/ha(483 kg/ha). The increase in grain yield due to application of nitrogen and phosphorus was due to significant improvement in the yield components (Number of pods, pod weight and grain weight per plant and 1000 grain weight).
