Response of Different Organic Sources of Nutrients on Growth and Yield of Basmati Rice

Abstract

The field experiment was conducted at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) during kharif season 2022 and 2023. The experiment was conducted under RBD design with ten nutrient management treatments viz. T₁: Control, T₂: Recommended dose of fertilizers NPK (120:60:40), T₃: 50 % N through Dhaicha + 25% N through FYM + 25% N through Vermicompost, T₄: 50 % N through Dhaicha + 25% N through FYM + 25% N through Vermicompost + Consortia + Biostimulant, T₅: 25 % N through Dhaicha + 25% N through FYM + 50 % N through Vermicompost, T_6: 25 % N through Dhaicha + 25% N through FYM + 50 % N through Vermicompost + Consortia + Biostimulant, T₇: 1/3 N through Dhaicha + 1/3 N through FYM + 1/3 N through Vermicompost, T₈: 1/3 N through Dhaicha + 1/3 N through FYM + 1/3 N through Vermicompost + Consortia + Biostimulant, T₉: 50 % N through FYM + 50 % N through Vermicompost, and T₁₀: 50 % N through FYM + 50 % N through Vermicompost + Consortia + Biostimulant. On the basis of pooled data, the yield attributes characters like: plant height, dry matter accumulation, number of effective tillers was found under treatment T₂ (Chemical fertilizer 120:60:40). Similarly, yield attributing characters such as panicle length (27.61 cm), filled grain per panicle (72.57), 1000 grain weight (27.38 g) were recorded maximum under (Recommended dose of fertilizers, NPK :120:60:40) and found at par with 50 % N through Dhaicha + 25% N through FYM + 25% N through Vermicompost + Consortia + Biostimulant (T₄). Highest grain yield (39.44 q/ha) and straw yield (64.47 q/ha)) was recorded under RDF followed by treatment T₄, and T₃ during both the years of experimentation.
