Assessment of Different Quality Parameters of Local Scented Rice (Oryza sativa L.) Grain as Influenced by Various Nutrient Management Practices in the New Alluvial Zone of West Bengal

摘要

A field experiment was conducted to assess the different quality parameters of local scented rice as influenced by various nutrient management practices 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 (V,), 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 (Tj), 50% RecommendedNPK as Chemical Fertilizer + 50% Recommended NPK as Vermicompost (T2), 75% Recommended NPK as Chemical Fertilizer + 25% Recommended NPK as Vermicompost (T3), 100% Recom-mended NPK as Chemical Fertilizer (T4), 100% Recommended NPK as Vermicompost (T5) and Control (T ) in the sub plots in all possible combinations replicated thrice. The highest amylose content of the rice grains was found under the varietal treatment Dehradoon (V) with the nutrient management T, (100% recommended NPK as chemical fertilizer) while the other quality parameters viz. head rice recovery kernel length before and after cooking and the elongation ratio was highest under T5 nutrient management (100% recommended NPK as Vermicompost).
