Abstract
A field experiment was conducted during the Kharif season of 2019 at Instructional Farm, BCKV, Jaguli, Nadia (West Bengal) to study the Growth, yield, and soil nutrient status of Kharif rice (Oryza sativa L.) as influenced by integrated nutrient management under lower Gangetic plains in a Randomized Block Design (RBD) having three replications. Outcomes revealed that rice plots fertilized with NPK@125% of RDF(100:50:50 kg/ha) + FYM@ 5 t/ha +vermicompost @2.0 t/ha recorded the highest plant height, elongation rate dry matter accumulation, crop growth rate and no. of tillers per hill. The maximum grain (5.25 t/ha) and straw yield (5.84 t/ha) as well as soil nutrient status after harvest of Kharif rice was recorded with NPK@125% of RDF (100:50:50 kg/ha)+FYM@ 5 t/ha+ Vermicompost @2.0 t/ha followed by NPK@ 80:40:40 kg/ha + ZnSO4@25 kg/ha which is 53.72% higher over control.
