Abstract

The field experiment was conducted at Crop Research Farm, Naini Agriculture Institute, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Zaid 2022 on sandy loamy soil. The experiment was laid out in Randomized Block Design. The experiment consists of treatments i.e., VAM (20g/kg seed) + Phosphorus 30kg ha-1, PSB (20g/kg seed) + Phosphorus 30kg ha-1, VAM + PSB (40g/kg seed) + Phosphorus 30kg/ha, VAM (20g/kg seed) + Phosphorus 40kg ha-1, PSB (20g/kg seed) + Phosphorus 40kg ha-1, VAM + PSB (40g/kg seed) + Phosphorus 40kg/ha, VAM (20g/kg seed) + Phosphorus 50kg ha-1, PSB (20g/kg seed) + Phosphorus 50kg ha-1, VAM + PSB (40g/kg seed) + Phosphorus 50kg/ha, including control i.e., application of 20-40-20 kg NPK ha-1 (Farmer practice), which are replicated thrice. The variety PDM-139 SAMRAT green gram was sown in February 2023. The results of the experiment revealed that the application of VAM + PSB @ (40g/kg seed) along with 50 kg ha-1 of phosphorus significantly increased the growth parameters viz., plant height (32.94 cm), plant dry weight (42.73 g plant-1), crop growth rate (72.1 g m-2 day-1), relative growth rate (2.16 g m-1 day-1), branches per plant (6.53), nodules per plant (16.4) and yield parameters viz, pods per plant (19.20), seeds per pod (11.87), test weight (40.0g), seed yield (1,620 kg ha-1), haulm yield (1,022.22 kg ha-1), harvest index (49.30%) over control. This treatment also showed its positive effect on economics viz., gross returns (Rs. 1,45,770 ha-1), net return (Rs. 1,04,120.40 ha-1) and benefit cost ratio (2.50).

Keywords: Green gram, VAM, PSB, phosphorus, growth parameters, yield parameters, economics
