Effect of integrated nutrient management and plant geometry on phenological observation of rice (Oryza sativa L.) under SRI technique

The present investigation was conducted at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Acharya Narendra Nagar (Kumarganj), Ayodhya (U.P.) during Kharif seasons with the objective to know the effect of integrated nutrient management and plant geometry on growth and yield attributes of rice varieties. The study comprised six treatments of integrated nutrient management (F₀: Control, F₁: RDF (120:60:60) F₂: 50% RDF + 50% Vermicompost, F₃: 75% RDF + 25% N through Vermicompost, F₄: 50% RDF + 50% N through FYM F₅: 75% RDF + 25% N through FYM) with two varieties namely NDR-359 and Sarju 52 and two plant geometry (a) S₁: 20 cm X 20 cm. (b) S₂: 30 cm X 30 cm. The experiments were conducted in Factorial Randomized Block Design (R.B.D.) with three replications. Maximum days taken to 50% heading and maturity was recorded with the application of F₂ (50% RDF + 50% N through vermicompost), varieties (NDR-359) and plant geometry (20 cm ×20 cm). It was at par with F₄ (50% RDF + 50% N through FYM).
