Abstract: The investigation was conducted to know the effect of micronutrients, chemicals and plant growth regulators on growth and yield attributes of banana Cv. Grand Naine during 2017. The experiment was laid out in Randomized Block Design with three replications and eight treatments. The foliar application of combination with different concentrations of micronutrient mixture (Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%)) and different concentration plant growth regulators like GA3 (200 and 300 ppm), Benzyle Adenine (10 and 20 ppm) and Potassium Dihydrogen Phosphate (0.5 and 1%) were given at 5th and 7th month after planting and emergence of last hand. The results revealed that growth attributes such as height of plant (189.48 cm) and girth of stem (65.38 cm), length of finger (17.99 cm), number of hands per bunch (9.08) was found significantly maximum in treatment T4 i.e. spraying of Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%) + GA3 (300 ppm) 18.69, 24.48, 21.96 and 27.17 per cent, respectively more as compared to control. Maturity attended at crop duration 344.65 days, which was found minimum (5.48%) in treatment T6 i.e. Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%) + BA (20 ppm) than the control (364.67 days). The significantly the highest yield attributes i.e. weight of bunch (26.04 kg and 25.82 kg) and average yield (116.38 Mt and 112.63 Mt/ha) in the treatment T6 i.e. Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%) + BA (20 ppm) and T7 i.e. Zn (0.5%) + Fe (0.2%) + Cu (0.2%) + B (0.1%) + KH2PO4 (0.5%), respectively, as compared to control. which had significant increment i.e 45.78 and 41.08 per cent, respectively. It is inferenced that the foliar application of micronutrients with GA3 was found the best to improve the growth and with BA and KH2PO4 showed the best response in increasing the yield in banana.
