Abstract

The field experiment was carried out on sandy loam soil at Crop Research Farm, Naini Agricultural Institute, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) in the Kharif season of 2020. Randomized Blocks Design was used to set up the experiment and consisting of ten treatment combinations which were replicated thrice. There have been significant and ongoing efforts to boost pulse production by combining chemical fertilizers with biofertilizers. Despite the fact that India began commercially producing biofertilizers in the late 1970s, continued efforts are still required to create consistent yield responses in the efficient biofertilizer technology. The experiment's findings showed that with dual inoculation of PSB and VAM and 55 kg of phosphorus per hectare, plant height (81.09 cm), yield attributing parameters such as pods per plant (14.73), seeds per pod (8.85), test weight (80.19 g), seed yield (2.62 t/ha), stover yield (6.45 t/ha). The experiment's economics, or the highest gross return of INR 88390.42 per hectare and the highest net return of INR 59808.94 per hectare, were likewise achieved with the dual inoculation of PSB and VAM coupled with 55 kg of phosphate per hectare, whereas maximum benefit cost ratio (2.14) was recorded in co-inoculation of PSB and VAM with 45 kg P/ha.

Conclusion

Based on the results of one-year experimentation, it may be concluded that when comparing the various treatments, it was observed that the combined inoculation of PSB and VAM with 55 kg of phosphorus per hectare produced the highest yield attributes, harvest index, seed yield, and stover output. Maximum gross return and net return ratio was also recorded with the same, while thorough going benefit cost ratio was observed in combined inoculation of PSB and VAM with 45 kg P/ha. Acceptance of any agricultural recommendation will mainly depend on its benefit cost ratio, therefore among the two treatments i.e., PSB + VAM + 55 kg P/ha and PSB + VAM + 45 kg P/ha latter treatment was found to be more economically feasible for farmer’s practice.
