Abstract
An investigation was made to determine the effect of foliar application of micronutrients on the growth and yield of onion cv. NHRDF Red-4. The research was conducted at Dr. B.R. Choudhary Agricultural Research Station, Mandor, Jodhpur during Rabi seasons of 2022-23 and 2023-24. The experiment was laid out in a randomized block design with eight treatment combinations and three replications. The experiment consisted eight micronutrient treatments. The results indicated that the treatment T8 (ZnSO₄ 0.5% + FeSO₄ 0.5% + Boron 0.25%) significantly improved growth and yield parameters over other treatments. T8 exhibited the highest plant height, number of leaves, neck thickness, bulb dimensions, bulb weight, TSS and bulb yield. This treatment recorded the highest net profit (₹2,06,621/ha) with the most favorable benefit-cost ratio (3.76). In the present study, Treatment T8 exhibited 28.14% increase in yield and 36.83% increase in net return over the control.
