Abstract
A field experiment was conducted to study the effect of nutrient management on the yield & yield attributes in scented rice cultivars in the New Alluvial Zone of West Bengal. 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 highest grain yield and harvest index was achieved when the local scented rice cultivar Dehradoon (V3) was grown with 100% NPK as Chemical fertilizer (T4). However the nutrient management practice with 100% Recommended NPK as Vermicompost (T5) recorded the highest panicle length and the highest test weight was recorded under 50% Recommended NPK as Chemical Fertilizer + 50% Recommended NPK as Vermicompost (T2).
