Effect of different nano micronutrient on yield of mango (Mangifera indica L.) CV. Amrapali

A field experiment was carried out in 2024, at the Horticultural Research Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, for evaluating the effect of different nano micronutrient on yield of mango (Mangifera indica L.) cv. Amrapali. The experiment was conducted using a completely randomized design with nine treatments (T1: Nano Zn 1.0 ml/L, T2: Nano B 1.0 ml/L, T3: Nano Fe 1.0 ml/L, T4: Nano Zn 1.0 ml/L + B 1.0 ml/L, T5: Nano Zn 1.0 ml/L + Fe 1.0 ml/L, T6: Nano B 1.0 ml/L + Fe 1.0 ml/L, T7: Nano Zn 1.0 ml/L + B 1.0 ml/L + Fe 1.0 ml/L, T8: Micronutrient 1% ZnSO4 + 0.5% Borax, T9: water spray) All treatments were applied through foliar application and repeated twice, at 50 percent flowering and at one month after 1st spray during the year 2024. Among the treatments, the foliar application of nano Zn 1.0 ml/L + nano B 1.0 ml/L + nano Fe 1.0 ml/L significantly enhanced yield parameters, including no. of fruit set per panicle (at pea stage) (35.35), no. of fruit set per panicle (at harvest stage) (1.52), no. of fruit per tree (at harvest stage) (363.33), fruit length (10.54 cm), fruit weight (180.26 g), fruit girth (17.31 cm), pulp weight (115.68 g), peel weight (35.19 g), fruit yield (63.03 kg/tree and 17.46 t/ha) and lowest stone: pulp ration (0.25).
