Abstract:
A field experiment entitled “Effect of Phosphorus and Phosphate Solubilizing Microorganisms on Soil Fertility and Yield of Mungbean [Vigna radiata (L.)Wilczek]” was conducted during Kharif season 2018 at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan). The experiment consisted 16 treatments combination of four levels of phosphorus viz., Control, 20, 40 and 60 kg P₂O₅ ha^-1 and four levels of phosphate solubilizing microorganisms (PSM) viz., Control, Pseudomonas fluorescens, Aspergillus awamori and Pseudomonas fluorescens + Aspergillus awamori and replicated thrice in randomized block design. Mungbean var. IPM-03-2 was taken a test crop. Results indicated that the number of total and effective root nodules, fresh and dry weight of root nodules, leghaemoglobin content in root nodules, protein content, seed and straw yield in soil at harvest of crop were found significantly maximum upto the level of 40 kg P₂O₅ ha^-1 over control and 20 kg P₂O₅ ha^-1. Among the treatments of different PSM, Pseudomonas fluorescens + Aspergillus awamori resulted in significantly maximum increase in the number of total and effective root nodules, fresh and dry weight of root nodules, leghaemoglobin content in root nodule, protein content, seed and straw yield in soil at harvest of crop as compared to control, as well as individual inoculation of Pseudomonas fluorescens and Aspergillus awamori. However seed inoculation with Pseudomonas fluorescens and Aspergillus awamori individuallyat par.
