Abstract: The present experiment was carried out at Horticultural Research Farm, Department of Horticulture, B.A. College of Agriculture, Anand Agricultural University, Anand during spring- summer season for two years on a mango cultivar Mallika to assess the effect of growth regulators (NAA and GA3) and micronutrients (ZnSO4 and borax) on and yield parameters and quality of mango. The experiment comprised of 15 treatments with different PGR’s and micronutrients i.e., NAA (T1 = 20 mg/l, T2 = 40 mg/l), GA3 (T4 = 25 mg/l, T5 = 50 mg/l) and zinc sulphate (T5 = 0.5%) and borax (T6 = 0.2 %) and combined treatments i.e. NAA 20 mg/l + ZnSO4 0.5 % (T7), NAA 20 mg/l + Borax 0.2 % (T8), NAA 40 mg/l + ZnSO4 0. 5 % (T9), NAA 40 mg/l + Borax 0.2% (T10), GA3 25 mg/l + ZnSO4 0.5 % (T11), GA3 25 mg/l + Borax 0.2 % (T12), GA3 50 mg/l + ZnSO4 0.5% (T13), GA3 50 mg/l + Borax 0.2% (T14)along with water spray/control (T15)were applied as foliar spray at full bloom, pea and marble stage of fruit growth. Combined effect of NAA 20 mg/l + Borax 0.2% significantly increased the number of fruits per plant (213.33), fruit yield (79.97 kg/tree) and various biochemical properties such as titratable acidity (%), TSS (%), reducing sugar (%), non reducing sugar (%), total sugar and ascorbic acid (mg/100g).
