Effect of Organic Nutrient Sources on Soil Nutrient Level in Pea (Pisum sativum L.)

An experiment was undertaken during rabi season of the year 2020-21 to study the effect of bio-fertilizers and organic nutrient sources on residual soil nutrient status in pea. The study comprised of seventeen treatments with different combinations of bio-fertilizers viz., Rhizobium and Phosphate Solubilizing Bacteria (PSB) and organic manures viz., FYM and vermicompost. The investigation revealed that minimum soil pH (6.96), maximum soil organic carbon (0.76 %), available nitrogen (259.36 kg/ha) and available phosphorus (26.98 kg/ha) were obtained with treatmentT13 (Rhizobium+ PSB + FYM). The maximum soil electrical conductivity (0.208 dSm-1) and available potassium (174.65 kg/ha) were obtained with treatment T17 [Recommended Dose of Fertilizer (25N: 60P:60K kg/ha)]. Application of Rhizobium, Phosphate Solubilizing Bacteria along with FYM resulted in maximum benefit: cost ratio of 2.18.
