Abstract: The present investigation entitled “Effect of micronutrients on fruit quality, shelf life and Economics of Tomato (Solanum lycopersicum L.) cv. PKM-1” was under taken at vegetable research field, Department of Horticulture, Allahabad School of Agriculture, Sam Higginbottom Institute of Agriculture, Technology & Sciences (SHIATS), Allahabad during rabi season (2015-2016). The experiment was laid out in Randomized block design with 13 treatments and each replicated thrice. The treatments consists of different combinations of micronutrients i.e., zinc, boron, copper and iron. Among these thirteen treatments, treatment T₁₂ (ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @500ppm) was recorded the maximum maximum fruit yield per ha (33.62t) followed by treatment T₁₁ (ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @250ppm). Among the quality parameters TSS (5.0⁰B^rix) was found maximum in treatment T₁₁(ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @250ppm) followed by treatment T₁₂(ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @500ppm) whereas juiciness (31.24%), titrable acidity (1.06%), Ascorbic acid content (26.67mg/100 g fruit juice) and shelf life (11.39) days at normal room temperature was recorded maximum in treatment T₁₁(ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @250ppm) followed by T₁₂(ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @500ppm). Maximum gross returns (Rs.3, 37,700 ha^-1), net returns (Rs. 2,14,925 ha^-1) and B: C ratio (2.75:1) was found to be best with treatment with T₁₂ (ZnSO₄ +B₃HO₃ +CuSO₄ +FeSO₄ @500ppm)
