Application of growth substances through tree injection in banana for increasing yield and fruiting characters

The present investigation was carried out on banana cv. Grand Naine, trated with nine chemical treatments viz., control (T₁), GA₃@ 10 ppm (T₂), GA₃@ 20 ppm (T₃), GA₃@ 30 ppm (T₄), BA @ 2.5 ppm (T₅), BA @ 5.0 ppm (T₆), NOVEL⁺ @ 0.5% (T₇), NOVEL⁺ @ 1.0% (T₈), NOVEL⁺ @ 1.5% (T₉), applied through injection at the time of bell emergence. The results revealed that the injection of GA₃ @ 30 ppm (T₄) tended to show the maximum bunch weight (36.38 kg), fruit yield (126.31t/ha), bunch length (101.78 cm), bunch girth (119.17 cm), finger length (22.96 cm), finger girth (13.99 cm) and finger weight (205.78 g), took minimum days from flowering to harvest (89.28). However, the maximum number of fingers per bunch (179.89) and number of hands per bunch (14.06) were observed under the injection of NOVEL⁺ @ 1.5% (T₉) followed by GA₃ @ 30 ppm (T₄).
