GROWTH AND YIELD OF BITTER GOURD (Momordica charantia L.) INFLUENCED BY GIBBERELIC ACID AND BORON

Abstract

The field experiment was carried during the period of April to June 2016 at Horticulture farm of Sher-e-Bangla Agricultural University Dhaka-1207, Bangladesh. The experiment was laid out in the Randomized Complete Block Design with three replications. Treatment consisted of four levels of plant growth regulator i.e. G 0 hormone, G 1 boron, B 1 = 50 mg/l, G 2 = 15 ppm, B 2 =100mg/l, G 3 =150mg/l; and three levels of boron i.e. B 0 = 30 ppm. Result revealed that the vegetative growth namely plant height was highest (255.38 cm) in G 2 of primary branches plant -1 B 2 and lowest (149.42 cm) in G 0 was highest (12.30) in G 2 number of secondary branches plant G 0 B 0 -1 B 2 were highest (9.22) in G 2 B 0 =No =No , number and lowest (4.09)in G 0 . The reproductive development i.e. the number of male flowers plant (36.47) in G 2 B 2 and lowest (14.23) in G 0 highest (20.17) in G 2 (17.33) in G 2 B 2 B 2 and lowest (9.20) in G 0 and lowest (7.16) in G 0 and lowest (21.66 t ha -1 ) in G 0 B 0 B 0 B 0 B 2 and lowest (2.19) in -1 , number of female flowers plant B 0 , number of fruits plant and yield was highest (39.06 t ha . The combined effect G 2 B 2 -1 B 0 was highest -1 , was was highest -1 ) in G 2 produced the best result for all vegetative growth, reproductive development and yield of bitter gourd. Therefore, the combination of G 2 B 2 could be used to cultivate bitter gourd.
