Abstract

A field experiment was carried out on loamy sand soil at Anand Agricultural University, Anand, Gujarat during semi-rabi season of 2021 under middle Gujarat condition to evaluate the effect of phosphorus management through PROM (Phosphate Rich Organic Manure) and PSB (Phosphorus solubilizing Bacteria) in semi-rabi green gram. The experiment was laid out in Factorial Randomized Block Design with three replications. The treatment combinations comprised three phosphorus levels viz., P1: 30 kg P2O5/ha, P2: 40 kg P2O5/ha and P3: 50 kg P2O5/ha and five biofertilizer (PSB) treatments viz., B0: Control, B1: Seed treatment (5ml/kg seed), B2: Drenching with PSB at 20 and 40 DAS(1 lit/ha), B3: Seed treatment fb (Followed by) Drenching at 20 DAS, and B4: Seed treatment fb Drenching at 20 and 40 DAS. The green gram was grown with standard package of practices. The results of the experiment revealed that significantly higher number of pods/plant (4.20), pod length (8.95 cm), seed yield (1176 kg/ha), stover yield (2262 kg/ha), test weight (51.96) and phosphorus content in seed (0.49 %) and stover (0.159 %) was found with application of 50 kg P2O5/ha (P3) which was found at par with application 40 kg P2O5/ha (P2). Nitrogen and phosphorus uptake in seed and stover also follows same trend. Under biofertilizer treatment, Seed treatment fb Drenching at 20 and 40 DAS(B4) recorded higher yield attributes and yield of green gram viz., number of pods/plant (4.38), pod length (8.90 cm), seed yield (1207 kg/ha) and stover yield (2305 kg/ha). Quality parameters viz; phosphorus content in seed and stover as well as nitrogen and phosphorus uptake in seed and stover were also increased with application of treatment B4 (Seed treatment fb Drenching at 20 and 40 DAS)followed by treatment B3 (Seed treatment fb Drenching at 20 DAS).

Conclusion

On the basis of the results obtained from the present investigation, it is indicated that for accruing higher yield and quality in green gram variety GAM 5 should be cultivated in semi rabi season with the application of 40 kg P2O5/ha through PROM (387 kg/ha) and seed treatment with PSB followed by drenching of PSB at 20 DAS.
