Influence of Integrated Nutrient Management (INM) on Bulb Yield and Profitability of Onion (Allium cepa L.) Crop in Western Uttar Pradesh, India

A field experiment was carried out at Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) 250110 during the Rabi seasons of year 2021-22 and 2022 to fulfil various objectives of yield and profitability of bulbs of onion for western Uttar Pradesh climatic conditions. A total of eleven treatments were used in Randomized Complete Block Design (RCBD) with three replications. Out of the eleven treatments, T7 - 75% RDF + FYM@ 2 t/ha + VC@ 1 t/ha + Biofertilizers (Azospirillum + PSB @ 5 kg/ha each) had a beneficial effect on maximum bulb yield (337.49 q/ha), net return (Rs. 208438.14 ha-1) and cost-benefit ratio (4.29) followed by 75% RDF + Biofertilizers (Azospirillum + PSB @ 5 kg/ha each). Whereas, the lowest bulb yield (122.16 q/ha) was observed in T1 – Control treatment followed by T8- 50% RDF + FYM @ 12 t/ha. While the minimum net return (Rs. 48307.20 ha-1) and cost-benefit ratio (1.97) were recorded in T1 – Control treatment followed by treatment T4- 75% RDF + FYM @ 6 t/ha.
