EFFECTS OF VARIETY AND NITROGEN ON VEGETATIVE GROWTH, MORPHOLOGY AND HEAD YIELD OF BROCCOLI (Brassica oleracea var italica L.)

Abstract

An experiment was conducted at the Farm of Sher-e-Bangla Agricultural University, Dhaka during October 2017 to March 2018 to examine the effects of variety and nitrogen on vegetative growth, morphology and curd yield of broccoli (Brassica oleracea var italica L.). The experiment consisted of two varieties, namely ‘Premium crop’ and ‘Green sprouting’ and four different levels of nitrogen viz. 0 kg ha -1 , 100 kg ha -1 , 200 kg ha -1 and 300 kg ha . The experiment was laid out in a two factorial Randomized Complete Block Design with three replications. There were 8 treatment combinations in all. Variety of Green sprouting gave maximum plant height, number of leaves plant , stem length of curd, stem length, diameter of primary curd, weight of primary curd, number of secondary curd plant -1 , weight of secondary curd plant . The maximum curd yield (19.28 t ha -1 ) was recorded from ‘Green sprouting’. Application of 200 kg N ha -1 recorded maximum plant height, leaves plant , stem length of curd, head length, diameter of primary curd, weight of primary curd, number of secondary curd plant -1 , weight of secondary curd plant and the highest curd yield (16.68 t ha -1 ). Application of 200 kg N ha coupled with ‘Green sprouting’ gave the maximum curd yield of 21.08 t ha
