EFFECT OF NYLON NET, KAOLIN AND 4-CPA ON GROWTH AND YIELD OF BELL PEPPER (Capsicum annuum)

Abstract

An experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to determine the response of nylon net, kaolin and plant growth regulator 4-CPA on growth and yield of capsicum. The experiment consisted of two factors: Factor A: Use of nylon net and kaolin as P 0 : Open Condition (control); P 1 : Kaolin Spray; P ii 2 : Nylon net condition; P : Use of nylon net + kaolin and Factor B: Application of 4-CPA as H : Control (water spray), H : 4-Chloro Phenoxy Acetic Acid (4-CPA) @ 4000 ppm. Two factorial experiments were laid out in a Randomized Complete Block Design with four replications. In case of nylon net and kaolin, the maximum yield (48.06 t/ha) was attained from P 1 , while the minimum yield (18.58 t/ha) from P 0 3 . For plant growth regulator 4-CPA, the highest yield (34.80 t/ha) was recorded from H 1 , whereas the lowest (29.20 t/ha) from H . Due to the interaction effect of nylon net, kaolin and 4-CPA, the highest yield (50.55 t/ha) was found from P 3 H 1 , while the lowest yield (16.89 t/ha) from P combination with nylon net, kaolin and 4-CPA was found best for growth and yield of bell pepper.
