Effect of phosphorus and bio-fertilizers on nutrient content and its uptake by mothbean (Vigna aconitifolia (Jacq.) Marechal

A field experiment was conducted to study the effect of four levels of phosphorus and four levels of bio-fertilizers. The results showed that application of phosphorus significantly increased nitrogen, phosphorus and potassium contents by seed and straw and total NPK uptake by mothbean up to 40 kg P2O5 ha−1 over lower doses. Dual inoculation of Rhizobium + phosphate solubilizing bacteria significantly improved the nitrogen, phosphorus and potassium contents of seed and straw, total NPK uptake by plant, seed and straw yields over no inoculation and single inoculation either with Rhizobium or PSB (have at par with each other) increased the nutrient contents and their uptake of mothbean over no inoculation.
