Abstract: The experiment framed was intended to study the effects of soil and foliar application of zinc, iron and boron on quality of guava and also to find out the economic dose of zinc, iron and boron. The experiment was conducted in a well-established Sardar guava orchard of fifteen years age planted at 6 x 6 m spacing during Mrig bahar 2019 with trees having uniform growth and vigor. The results of the present investigation clearly indicated that, different growth, yield and quality parameters of guava were significantly influenced due to different treatments of micronutrients. The physical and chemical quality attributes were also maximum with the said treatment. The highest gross monetary returns (Rs. 5,66,195/ha), net monetary returns (Rs.3,36,611/ha), Benefit: Cost ratio (2.47) were recorded with soil and foliar application of 100g ZnSo₄ + 100g FeSo₄ + 25g Borax + 0.5% ZnSo₄ + 0.5% FeSo₄ + 0.2% Borax (T₉).
