Effect of different levels of spacing and organic fertilizers on growth and yield of summer moong (Vigna radiata L.)

Green gram cultivar GM-4 performed better by recording higher number of branches per plant (3.17), dry matter accumulation per plant at both 30 DAS (7.19 g) and at harvest (14.91 g) and dry weight of root nodules per plant at both 30 DAS (2.25 g) and at harvest (3.41 g), number of pod per plant (26.44), length of pod (6.14 cm) and test weight (38.90 g) when sowing with 45 cm row spacing over 30 cm row spacing but seed yield (930 kg ha-1) and Stover yield (2151 kg ha-1) where recorded with 30 cm row spacing over 45 cm row spacing. Application of 100% RDF recorded higher values for number of branches per plant (2.83), dry matter accumulation per plant at harvest (14.50 g) and dry weight of root nodules per plant at both 30 DAS (2.21 g) and at harvest (3.39 g), length of pod (6.19 cm) and test weight (39.35 g), seed yield (945 kg ha-1) and Stover yield (1900 kg ha-1) over 75 % RDF and control. Inoculation of Rhizobium and PSB also improve growth and yield parameters. generally , for obtaining higher yields green gram variety GM-4 to be grown during summer season with 30 cm row spacing and fertilizing the crop with 100% RDF (20-40-00 kg N-P2O5-K2O ha-1) with inoculation of Rhizobium and PSB.
