Abstract: Effect of micronutrients on growth, yield and quality parameters of sweet orange was studied at Experimental field of department of Horticulture, Collage of Agriculture, RVSKVV, Gwalior (M.P.). Foliar application of 4g CuSO₄ (Copper sulfate)+ 2g FeSO₄ (Ferrous sulfate), + 2g Borax+ 4g ZnSO₄ (Zinc sulfate) + 4g MgSO₄ (Magnesium sulphate) + 10g lime per liter water during the mid of March and 1^st week of July with 600 N + 500 P+300 K g/tree on sweet orange gave maximum Yield per tree (41.03 kg), Number of fruits/tree (248), Fruit weight (167 g), Fruit length (11.8 cm), Fruit diameter (21.8 cm) and good quality fruits Juice (56.08 %) (Titratable Acidity (0.78%), Ascorbic acid (58.04 mg/100ml) with Total Soluble Solids (11.6 ^oBrix). Therefore, application of this dose of micronutrient combination will improve yield and fruit quality in sweet orange of these micronutrients as a result of which the orchardist will be economically benefited.
