PERFORMANCE OF DIFFERENT VARIETIES OF SWEET PEPPER ON THE GROWTH AND YIELD UNDER PROTECTED STRUCTURES

Abstract

A field experiment was conducted at the “Horticulture Farm” of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of October 2021 to April 2022 in Rabi season to perform a study on the performance of different varieties of sweet pepper on the growth and yield under protected structures. The experiment consisted of two factors and followed Randomized Complete Block Design (RCBD) with three replications. Factor A: Protected structures, i.e. T 1 = Open field, T 2 = Net house and T 3 = Poly tunnel and Factor B: Varieties, i.e. V 1 = BARI Mistimorich 1, V 2

= BARI Mistimorich 2 and V 3 = California Wonder. Experimental results revealed that different protected structures and varieties significantly influenced the growth and yield of sweet pepper. In case of protective structures, the highest yield per plant (0.81 kg), yield per plot (5.65 kg) and yield per hectare (50.83 t) were obtained from T 2 (Net house) treatment. Among different variety, V 2 (BARI Mistimorich 2) variety gave the highest yield per plant (0.72 kg), yield per plot (5.00 kg) and yield per hectare (45.00 t) of sweet pepper. In case of combination treatment, the highest yield per plant (0.94 kg), yield per plot (6.53 kg), yield per hectare (58.75 t) and benefit cost ratio (BCR) were obtained from the treatment combination T 2 V 2 (Net house + BARI Mistimorich 2) comparable to other treatment combination. Therefore, it was suggested that cultivation of BARI Mistimorich 2 along with net house (T 2 V 2 ) combination treatment would help to influence plant growth and increase its ability to enhanced better yield and quality production of sweet pepper.
