RESPONSE OF BELL PEPPER (Capsicum annuum) VARIETIES TO PLANT GROWTH REGULATORS

Abstract

The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to determine the response of bell pepper varieties to plant growth regulators. The experiment consisted of two factors: Factor A: Bell pepper (two varieties) V : BARI Misti Morich-1 and V G 2 0 1 : Exotic variety (Lamuyo); Factor B: Plant growth regulators (four levels) as : No plant growth regulator (water), G 1 : Gibberellic Acid (GA ) @ 100 ppm, G 2 : 4-Chloro Phenoxy Acetic Acid (4-CPA) @ 2000 ppm and G : Litosen @ 1000 ppm. The experiment was laid out in a Randomized Complete Block Design with three replications. In case of bell pepper varieties, the maximum yield (22.47 t/ha) was attained from V 2 , while the minimum yield (20.09 t/ha) from V . For plant growth regulators, the highest yield (25.17 t/ha) was recorded from G , whereas the lowest (15.33 t/ha) from G . Due to the interaction effect of variety and plant growth regulators, the highest yield (26.52 t/ha) was found from V 0 , while the lowest yield (14.51 t/ha) from V 1 G 0 . So, V 2 G (combination with Lamuyo and 4-CPA) was found best for growth and yield of bell pepper.
