Effect of Spacing and Biofertilizer on Growth and Yield of Greengram (Vigna radiata)

The present investigation entitled “Effect of spacing and biofertilizer on growth and yield of greengram (Vigna radiata)”, was conducted during the Kharif season of 2022 at the Crop Research Farm of the Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment with nine treatments and three replications was laid down in factorial randomized block design. The results showed that pre harvest observations like plant height (42.04cm), dry weight (6.79 g), number of branches (6.18) of plant were higher in T3 i.e. Application of Rhizobium and PSB along with the spacing of 30x10 cm, Number of nodules per plant (6.62) was higher in treatment 2 i.e. Application of PSB along with the spacing of 30x10 cm and the value of the treatment. Post-harvest data indicated that the number of pods/plant (23.74), number of seeds/pod (7.72), test weight (41.30 g), seed yield (1.69 t/ha), biological yield (5.61 t/ha), stover yield (3.83 t/ha) and harvest index (33.37%) were higher in treatment 3 i.e. Application of Rhizobium and PSB along with the spacing of 30x10 cm. The maximum cost of production and gross return was recorded higher under treatment 3 i.e. Application of Rhizobium and PSB along with the spacing of 30x10 cm is INR. 36500/ha and INR. 88500/ha, respectively. The net return (INR. 12500/ha) and B:C Ratio (2:4) was recorded higher under treatment 3 i.e. Application of Rhizobium and PSB along with the spacing of 30x10 cm.
