The experiment was conducted in a Randomized Block Design with 12 treatments viz T₁- Control, T₂ -ZnSO₄ (0.2%), T₃ - ZnSO4 (0.5%), T₄ – Borax (0.2%) T₅ – Borax (0.4%) T₆ – CuSO₄ (0.2%), T₇ - CuSO₄ (0.5%) T₈ - ZnSO₄ (0.5%) + Borax (0.4%) T₉- ZnSO₄ + CuSO₄ T₁₀ - Borax + CuSO₄ T₁₁ - ZnSO₄ + Borax + CuSO₄ (0.2% each), T₁₂ - ZnSO₄ (0.5%) + Borax (0.4%) + CuSO₄ (0.5%) and 3 replications, during 2022. Yield parameters i.e., number of fruits per tree, fruit yield per tree (kg), yield per hectare (tonnes) and economic parameters i.e., cost of cultivation, net return, gross return and cost-benefit ratio were recorded during the experimental period. There was a significant effect of foliar application of zinc, boron and copper on yield attributes and economic feasibility of lemon cv. Pant Lemon-1. This study revealed that optimum yield and maximum benefit-cost ratio were obtained by spraying a combination of zinc (0.5%), boron (0.4%) and copper (0.5%). It can be concluded that foliar spray of zinc sulphate (0.5%), borax (0.4%) and copper sulphate (0.5%) performed best when applied twice in the month of June and July under western Uttar Pradesh conditions.
