Abstract:
More than two-thirds of the world's soils are afflicted with phosphorus shortage (P). Agricultural output suffers because this phosphorus is unavailable to all but a tiny percentage of plants. To lessen the severity of the environmental impact, phosphorus-deficient soils have traditionally been fertilized. Improving agricultural management practices for sustainable crop output, including lowering phosphorus runoff, is the emphasis of this study. Investigating chemical fractionation mechanisms to distinguish between occluded P, acid-extractable calcium-bonded P, and non-occluded P is necessary for increasing Pi in mung bean (Vigna radiata) types and establishing net grazing systems. Phosphate (P) is known to be transferred between pools due to weathering, with the highest P retention rates found in clay-rich soils. Soil with a finer texture is better able to absorb and fix phosphorus, which means more nutrients and water can be made available to the plant when mung bean varieties are inoculated into it. More photosynthesis means more accumulated dry stuff. The P-treated variety of mung bean had the greatest yield index (13.28). Pods per plant (46.02), pods per crop (8.20), test weight (40.63 gm), pod weight (8.0 g), and seed weight (1.0 g) were all significantly increased with DAP (1.83 g). An increase in nodule count, leaf area index, plant height, grain yield, total chlorophyll content, and straw output of up to 40% was observed at higher P2O5 concentrations (2988 kilogrammes per hectare). Each plant developed the maximum number of nodules after receiving injections of PSB and Aspergillus awamori. The highest levels of chlorophyll were found in its leaves, and its plants were the largest and most productive overall. Liming improved mungbean yields in acid piedmont soil by raising the pH and altering other chemical characteristics. They claim that increasing India's output of pulses is necessary for the country to attain food security in the future. If farmers and extension workers want to see higher quality pulse yields and greater long-term profitability, they need to incorporate P nutrition into their balanced nutrient management programmes.
