Influence of integrated nutrient management (INM) practices on performance of boro rice (Oryza sativa L.) in new alluvial zone of West Bengal

Abstract

Integrated nutrient management became indispensable for the long-term benefits of maintaining soil health, sustaining production and reducing environmental pollution. Hence, a field experiment was conducted at Bidhan Chandra Krishi Viswavidyalaya, West Bengal during boro seasons of 2019 and 2020 to evaluate the growth and yield performance, nutrient uptake and economics of rice (cv. Satabdi) towards various INM practices. The experiment comprised of seven treatment combinations in Randomized Block Design with three replications. On the basis of pooled data, better performance regarding growth, yield, uptake (N, P and Zn) and economics were reflected from the integrated application of 2 t ha -1 vermicompost + 75% RDF + 25 kg ha -1 ZnSO 4 (soil application) than other treatments. Therefore, it can be concluded that 2 t ha -1 vermicompost followed by 75% RDF and 25 kg ha -1 ZnSO 4 application can be remunerative and promising combination for boro rice in new alluvial zone.
