GROWTH AND YIELD OF TOMATO AS INFLUENCED BY GA AND BORON

Abstract

An experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University during the period of October 2016 to March 2017 to evaluate the growth and yield of tomato as influenced by GA and boron. The experiment was laid out in the Randomized Complete Block Design with three replications. Treatment as four levels of GA 3 , viz. G 0 3 : Control, G : 100 ppm, G 3 : 120 ppm; and two levels of boron, viz. B 0 1 : 80 ppm, G : Control, B : 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 , fruit length, fruit girth, individual fruit weight, fruit weight plant -1 attributed the highest yield for the treatment G 2 (68.41 t ha -1 ) and B 1 -1 treatments (67.64 t ha ). For combined application, G 2 B gave the best result for all vegetative and reproductive growth and development. From this experiment it can be concluded that 100 ppm GA 1 3 with 5 kg Boron ha -1 treatment combination is suitable dose for higher yield of tomato.
