Abstract

The present study aimed to evaluate the effect of phosphate solubulizing bacteria and phosphorus levels on growth and yield of greengram (var. “WGG-42”) conducted during the kharif 2020 at Prakasam Krishi Vigyan Kendra (KVK), Jayaprakashnagar, Jammikunta, Karimnagar District-505122 Telangana. The experiment was laid out in Randomized Block Design with 9 treatments which included 3 levels of PSB (0%, 0.5% and 1%) and 3 levels of phosphorus (20kg, 40kg and 60kg) which replicated thrice. The treatment receiving PSB 1% and 20kg phosphorus produced significantly higher plant height (40.17cm), number of nodules/plant (21.73), number of branches/plant (5.93), plant dry weight (8.90g), crop growth Rate (4.51g/m2/day), relative growth rate (0.017g/g/day), number of pods/plant (37.70), test weight (37.70g), seed yield (1440.00kg/ha), stover yield (2400.66kg/ha), harvest index (40.02), gross return (97,920.00 INR/ha) net return (69,964.60 INR/ha), and B:C ratio (2.50). This experiment shows

Keywords

Mungbean, PSB and phosphorus.

Conclusion

Based on the findings it may be concluded that for optimum Seed yield and economics, the performance of Mungbean at PSB – 1% + Phosphorus – 20kg/ha is the best. The conclusion drawn based on the one season data only which require further conformation for recommendation.
