Impact of Spraying with some Micronutrients on onion (Allium Cepa L.) Yield and Economics of Onion
Micronutrients are essentially as important as macronutrients to improve growth, yield and quality in plants. Present experiment was conducted as on-farm testing at farmers’ field during Rabi season of 2021-22, 2022-23 and 2023-24 to assess the impact of essential micronutrients like zinc, magnesium, copper, manganese, iron, molybdenum and boron spray on growth, bulb yield and economics of onion crop. Two treatments i.e. T1- Farmers’ practice (without spray) and T2- foliar spray of ready-mix containing (Zn, Mg, Fe, Mn, Cu, Mo and Bo 0.25%) @ 2.5 ml/ litre at 30 and 45 days after transplanting of onion seedlings replicated at ten farmers field of Fatehabad district. The use of micronutrients as foliar spray was found effective in treatment T2 with the significantly highest bulb weight (54.48, 55.60 & 57.20g), bulb yield (198, 265 & 300 q/ha) during 2021-22, 2022-23 and 2023-24, respectively. Maximum net return (₹ 104400, 323000 & 98000/ ha) and benefit cost ratio (2.93, 4.19 & 2.89) were recorded in the treatment T2 whereas, in treatment T1 (farmers’ practices) net return were (₹ 91000, 292000 & 86500/ ha) and BC ratio (2.71, 3.92 & 2.69), respectively during 2021-22, 2022-23 and 2023-24. Therefore, the use of micronutrient application to be increases the production and recommended for onion cultivation.
