Effects of Nutrient Management on Growth Indices and Grain Yield of Different Crop Establishment Methods in Rice (Oryza sativa L.)

A field experiment was conducted during two consecutive Kharif seasons, 2021 and 2022 at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture Technology, Kumarganj Ayodhya (Uttar Pradesh, India) to assess the effect crop establishment methods nutrient management on growth indices yield rice (Oryza sativa L.). The in split plot design which comprised four methods. There are: M1 transplanting (Conventional); M2 direct seeded rice; M3 drum M4 broadcasting sprouted seed under puddled condition were kept main while five practices sub plot. They N0 Control; N1 Recommended dose fertilizer (150:60:40 kg/ha NPK); N2: RDF + Zn@5kg/ha; N3: S@40 kg/ha; N4: Zn S (@5 40 kg/ha). replicated three times. Significantly higher rate, absolute relative rate net assimilation grain recorded both years investigation. Among nutrients management; value all 150:60:60 NPK (5 kg/ha) Sulphur (40
