A study was conducted at Ri-Bhoi District of Meghalaya to evaluate the impact of vermicompost based integrated nutrient management on soil nutrient dynamics and its effect on productivity enhancement of Broccoli (Brassica oleracea var. Italica). The experiment was conducted at 2 selected villages of Ri-Bhoi District with 3 treatments viz., T1: Vermicompost @ 1.0 t/ha + 50% RDF (RDF: N: P2O5: K2O ::120: 80: 60 kg/ha), T2: Vermicompost@ 2.0 t /ha + Lime @ 500kg/ha + 2% urea spray at branching & pod initiation stage, T3: Farmers practice (imbalance fertilizer with N: P2O5: K2O:: 50:20:10 kg/ha) with 5 replications following randomized block design during the year 2017-18. From the results it is revealed that Vermicompost @ 1.0 t/ha + 50% RDF showed significant increase in yield and B.C ratio followed by Vermicompost@ 2.0 t /ha + Lime @ 500kg/ha + 2% urea spray at branching & pod initiation stage and Farmers practice. Moreover, improved soil nutrient status was achieved in T1 followed by T2 and T3 in the soil after the harvest of the crop as compared to the initial stage of soil before the implementation of Treatments.
