A study was conducted at farmers’ field of Ri-Bhoi District of Meghalaya to test the effect of organic sources of soil nutrient management with Lime for soil acidity management and for yield improvement of Rajma (Phaseolus vulgaris L.). The experiment was conducted by following 3 treatments: TO1: Lime @ 400 kg/ ha in furrows + FYM @ 5 t/ha + Neem cake @400 kg/ha+ vermicompost @ 5 t/ha + Azospirillum 10kg/ha, TO2: FYM @ 5 t/ha + Neem cake @400 kg/ha+ vermicompost @ 5 t/ha + Azospirillum 10kg/ha, TO3: Farmers’ Practice (FYM) (imbalance fertilizer with N: P2O5: K2O:: 30:20:12 kg/ha) with 5 replications following randomized block design during 2021-22. From the results it is revealed that TO1: Lime @ 400 kg/ ha in furrows + FYM @ 5 t/ha + Neem cake @400 kg/ha+ vermicompost @ 5 t/ha + Azospirillum 10 kg/ha had showed significant increase in yield i.e. 6.2 q/ ha and B:C ratio of 2.82 followed by FYM @ 5 t/ha + Neem cake @400 kg/ha+ vermicompost @ 5 t/ha + Azospirillum 10 kg/ha (4.3 q/ha yield, B:C ratio 2.15) and Farmers practice (2.21 q/ha yield, B: C ratio 1.7). Moreover, improved soil nutrient status was achieved in T1 followed by T2 and T3.
