Abstract: Studies on soil health as influenced by integrated nutrient management practice in different cultivars of local scented rice was conducted at the C Block Farm of BCKV, Kalyani, West Bengal during the Kharif season of 2011 and 2012. The experiment was carried out in split plot design taking three cultivars of scented rice viz. Gobindabhog (V₁), Kalonunia (V²) and Dehradoon (V₃) in the main plots and six levels of nutrient management viz. 25% Recommended NPK as Chemical Fertilizer + 75% Recommended NPK as Vermicompost (T₁), 50% Recommended NPK as Chemical Fertilizer + 50% Recommended NPK as Vermicompost (T₂), 75% Recommended NPK as Chemical Fertilizer + 25% Recommended NPK as Vermicompost (T₃), 100% Recommended NPK as Chemical Fertilizer (T₄), 100% Recommended NPK as Vermicompost (T₅) and Control (T₆) in the sub plots in all possible combinations replicated thrice. The BD, EC and pH decreased with incorporation of organics while organic C %, total N%, available P increased. Only the available K content recorded higher values with 100 per cent recommended NPK as chemical fertilizer (T₄).
