ABSTRACT
An experiment was conducted at Horticulture Farm, Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of October 2016 to March 2017 to evaluate the growth and yield of tomato as influenced by GA3 and boron. The experiment was laid out in the Randomized Complete Block Design with three replications. Treatment as four levels of GA3, viz. G0: Control, G1: 80 ppm, G2: 100 ppm, G3: 120 ppm and two levels of boron, viz. B0: Control, B1: 5 kg boron ha-1. Result indicated that the highest values of vegetative growth i.e. plant height and number of branches per plant and reproductive growth and development i.e. number of cluster plant-1, number of fruit plant-1, fruit length, fruit girth, individual fruit weight, fruit weight plant-1 attributed the highest yield for the treatment G2 (68.41 t ha-1) and B1 treatments (67.64 t ha-1). For combined application, G2B1 gave the best result for all vegetative and reproductive growth and development. From this experiment it can be concluded that 100 ppm GA3 with 5 kg Boron ha-1treatment combination is suitable dose for higher yield of tomato.
