Aim: The objective of the research was to study the effect of Integrated Nutrient Management on the yield attributing parameters of kharif onion. Study Design: The field experiment was carried out in Randomised Block Design (RBD). Place and Duration of Study: The experiment was conducted at the Research Farm of the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur U.P during the kharif seasons of 2021-22 and 2022-23. Methodology: An experiment was carried out during Kharif season in the years, of 2021-22 and 2022-23 both the year same time at Vegetable Research Farm, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kalyanpur, Kanpur. The experiment was laid out in randomized block design with three replications. The treatments consisted of T1- Control: T2- 100% RDF (NPK @ 120:60:80 kg/ha; T3- 75% RDF+ FYM 6 t/ha: T4- 75%RDF+ Vermicompost@2 t/ ha; T5- 75%RDF+FYM @ 3t/ha+vermicompost@1 t/ha ;T6- 75% RDF + FYM @ 3 t/ha + Vermicompost @ 1t/ha+ Biofertilizer (Azotobacter + PSB @ 5 kg/ha each):T7‑ 50% RDF + FYM @ 12t/ha; T8-50% RDF + Vermicompost @ 4t/ha: T9- 50%RDF+ FYM @ 6t/ha + Vermicompos @ 2t/ha: T10- 50%RDF + FYM @ 6t/ha + Vermicompost @ 2t/ha + Biofertilizer (Azotobacter + PSB @ 5 kg/ha each). Results: Results revealed that the treatment T10 (50% RDF +FYM @ 6 t/ha + Vermicompost @ 2t/ha+ Biofertilizer (Azotobacter + PSB @ 5kg/ha each) performed better with respect to yield attributing parameters characters such as Average bulb weight, A, B, C grade bulb percentage, days takes to harvesting, bolting percentage of bulb and double bulb Percentage. Conclusion: The study underscores the crucial need to shift towards Integrated Nutrient Management (INM), incorporating both organic and inorganic fertilizers. This transition is essential to protect soil fertility, maintain ecosystem health, and ensure sustainable food production for future generations.
