abstract
The present investigation was conducted at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during Kharif seasons with the objective to know the effect of integrated nutrient management and plant geometry on phenotypic and yield attributes of rice varieties. The study comprised six treatments of integrated nutrient management (F₀: Control, F₁: Recommended Dose of Fertilizer (120:60:60) F₂: 50% Recommended Dose of Fertilizer + 50% Vermicompost, F₃: 75% Recommended Dose of Fertilizer + 25% N through Vermicompost, F₄: 50% Recommended Dose of Fertilizer + 50% N through FYM F₅: 75% Recommended Dose of Fertilizer + 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 study revealed that the maximum nitrogen uptake by crop recorded in F₂ (50% Recommended Dose of Fertilizer + 50% N through vermicompost). The application of 50% Recommended Dose of Fertilizer + 50% N through vermicompost (F₂) was at par with F₄ (50% Recommended Dose of Fertilizer + 50% N through FYM).
