Effect of Integrated Nutrient Management on Growth of Onion (Allium Cepa L.)

The present investigation took place during the rabi season of 2021-22 and 2022-23 at the Experimental Farm, Department of Agriculture, School of Sciences and Agriculture located in Kasmabad, Monad University, Hapur, Uttar Pradesh. In the present investigation the design used for analysis of variables were Randomized Block Design (RBD) comprising 3 replications sixteen treatment combinations. The details of treatments comprised of T₁ Control (water spray), T₂ (100% RDF [NPK-120: 60: 60 kg/ha]), T₃ (75% RDF + 6.0 t/ha FYM), T₄ (75% RDF + 1.0 t/ha PM), T₅ (75% RDF + 2.0 t/ha VC), T₆ (75% RDF + 3.0 t/ha FYM + 0.5 t/ha PM), T₇ (75% RDF + 1.0 t/ha VC + 0.5 t/ha PM), T₈ (75% RDF + 6.0 t/ha FYM + Azotobacter (4 kg/ha)), T₉ (75% RDF + 1.0 t/ha PM + Azotobacter (4 kg/ha)), T₁₀ (75% RDF + 2.0 t/ha VC + Azotobacter (4 kg/ha)), T₁₁ (50% RDF + 12.0 t/ha FYM), T₁₂ (50% RDF + 2.0 t/ha PM), T₁₃ (50% RDF + 4.0 t/ha VC), T₁₄ (50% RDF + 6.0 t/ha FYM + Azotobacter (4 kg/ha)), T₁₅ (50% RDF + 2.0 t/ha PM + Azotobacter (4 kg/ha)) and T₁₆ (50% RDF + 2.0 t/ha VC + Azotobacter (4 kg/ha). From the above experimental finding it is concluded that the treatment T₈ (75% RDF + 6.0 t/ha FYM + Azotobacter (4 kg/ha) was found to be best in the terms of growth, and earliness in maturity of Onion evaluated for different doses of organic and inorganic fertilizers integrated together.
