Abstract

A field experiment on loamy sand soil was conducted in the kharif of 2020, at the Agronomy farm at S.K.N. College of Agriculture, Jobner (Rajasthan). The field experiment included four levels of PROM (Control, PROM equivalent to 20 kg, 40 kg, and 60 kg P2O5/ha), as well as four phosphatic inoculants (PSB, VAM, and PSB + VAM) thereby making 16 treatment combinations. The experiment was set up in Factorial Randomized Block Design with three replications. The application of PROM equivalent to 40 kg P2O5/ha, according to the results, considerably increased the amount of accessible P in the soil after harvest when compared to lesser levels. The most profitable level was determined to be applying PROM equivalent to 40 kg P2O5/ha, which yielded net returns of `37184/ha. The application of PSB + VAM led to a considerable increase in accessible N, P, and K in the soil after harvest. With a B:C ratio of 2.38, the dual inoculation of PSB+VAM likewise produced the highest net returns, at `43226/ha. The most effective treatment combination for increasing net return (`52400/ha) was dual phosphatic inoculation of PSB + VAM with application of PROM equivalent to 40 kg P2O5/ha, according to the results

Keywords

Net return, PROM, PSB and VAM

Conclusion

Based on the results of one year experimentation, it may be inferred that application of PROM equivalent to 40 kg P2O5/ha combined with dual phosphatic inoculation of PSB + VAM (P40IPV) was found the most superior treatment combination for obtaining higher net returns (`52400/ha) in cowpea
