The field experiment conducted during the Kharif season of 2023 aimed to assess the "Evaluation of Integrated Nutrient Management on Growth, Yield, and Economics of Transplanted Rice (Oryza sativa L.) Under Irrigated Condition" at Rama university Mandhana Kanpur, Uttar Pradesh focused on the transplanted rice variety Sarjoo-52. This study evaluated eleven treatment combinations, each replicated three times. Treatments are Control (T1), 100% RDF (T2), 75% RDF + 25% FYM (T3), 75% RDF + Azolla (T4), 75% RDF + 25% Poultry manure (T5), 50% RDF + 50% FYM (T6), 50% RDF + Azolla (T7), 50% RDF + 25% Poultry manure (T8), 50% RDF + Azolla + 25% FYM (T9), 50% RDF + Azolla + 25% Poulty manure (T10) and 50% RDF + 25% FYM + 25% Poultry manure (T11). The findings demonstrated the significant influence of integrated Nutrient Management (INM) on growth, yield, nutrient content and economic aspects of transplanted rice cultivation. Among the treatments, particularly the combinations involving 75% of the recommend dose of fertilizer (RDF) along with organic amendments like 25% poultry manure emerged as the most effective, yielding superior growth, yield quality and nutrient uptake followed by 100% RDF, 75% RDF + 25% FYM and 75% RDF with Azolla. These treatments performed to 100% RDF and combination with azolla or farmyard manure, indicating the effectiveness of integrated approaches over convectional fertilization methods. Furthermore, the economic analysis revealed that the combination of 75% RDF with 25% poultry manure not only resulted in the highest net returns but also exhibited the highest benefit cost ratio indicating its economic viability and superiority over other treatments in terms of profitability.
