Effect of phosphate-rich organic manure (PROM) on nutrient uptake and soil properties after harvest of Rajmah (Phaseolus vulgaris L.)

The research study, named “Effect of phosphate-rich organic manure (PROM) on productivity, nutrient uptake and economics in Rajmah bean (Phaseolus vulgaris L.)”, took place at the Agronomy farm of the College of Agriculture in Pune, Maharashtra, throughout the 2023-24 growing season. The experiment was arranged in a Randomized Block Design (RBD) consisting of seven treatments and three replications. The treatment T₃ (100% phosphorus through single super phosphate) recorded the significantly higher N, P and K content in seeds (3.55%, 0.77% and 0.90%) and stover (1.31%, 0.26% and 1.24%). The significantly higher N, P and K uptake by rajmah bean seeds (58.19 kg ha^-1, 12.56 kg ha^-1 and 14.70 kg ha^-1) and stover (31.90 kg ha^-1, 6.30 kg ha^-1 and 30.12 kg ha^-1) recorded by treatment T₃ (100% phosphorus through single super phosphate), which ultimately noted higher total uptake by rajmah bean. The highest available N, P, K (266.68, 30.60 and 373.23 kg ha^-1, respectively) were observed with the application of treatment T₄ (100% phosphorus through PROM).
