Response of promising - rainy summer season greengram (Vigna radiata (L) genotypes to phosphorus fertilization

Field experiments were conducted at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya College of Agriculture, Gwalior during two kharif and summer seasons of 2009 and 2010 to study the effect of phosphorus levels and genotype on growth, yield and economics of greengram. Two years pooled results showed that the application of 60 Kg P2O5 /ha registered significantly higher yield (11.52 and 8.41 q/h), yield attributing characters, harvest index (33.61 and 27.86) net retreturn and B:C ratio (3.0 and 2.27) as compared to 30 kg P2O5 /ha during both kharif and summer seasons respectively. Among the genotypes on the basis of pooled data, genotype TM 99-50 gave significantly higher seed yield (13 and 9 q/ha kharif and Summer) yield attributing characters harvest index (37.06 and 30.96%) net return (Rs. 33320 and 19820 /ha) and B:C ratio (3.73 and 2.69) as compare to other genotype during both kharif and summer seasons. The second best genotype was TM 98-50 to augment these parameters. The lowest parameters were recorded in case of HUM-1 in kharif and TRAM-1 in summer season.
