Abstract:
The field experiment was conducted during Zaid season (2021) at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P). The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The treatments consisted Bio- fertilizers and Zinc levels viz., whose effect is observed on Green gram. The experiment was laid out in Randomized Block Design, with ten treatments which are replicated thrice. Results obtained that the maximum plant height (48.40cm), number of nodules (6.99), number of branches (6.44), plant dry weight (8.21 g/plant) pods per plant (40.10), seeds per pod (10.77), Test weight (35.60 g), grain yield (9.93 q/ha) and stover yield (41.34 q/ha) were significantly influenced with application of Azotobacter (10 g/kg) + PSB (10 g/kg) + Zn3 @ 30 kg/ha and Maximum crop growth rate (15.24 g/m2 /day). Maximum net returns of 69230.67 INR/ha and B:C ratio 2.08 was recorded in treatment with application of Azotobacter (10 g/kg) + PSB (10 g/kg) + Zn3 @ 30 kg/ha. Therefore, it can be concluded that the application of Azotobacter (10 g/kg) + PSB (10 g/kg) + Zn3 @ 30 kg/ha was most productive and cost effective.
