EFFECT OF LEAF CLIPPING AND NITROGEN FERTILIZER ON GROWTH AND YIELD OF MUNGBEAN

Abstract

The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period of March to June 2018 to study the effect of leaf clipping and nitrogen fertilizer on growth and yield of mungbean. The treatment consisted of two leaf clipping viz. C 0 = No leaf clipping (Control), C 1 = Leaf clipping (Removal of leaves having no inflorescence) and five nitrogen fertilizer doses viz. N 0 = 0 kg urea ha -1 , N 1 = 25 kg urea ha -1 , N 2 = 50 kg urea ha -1 , N 3 = 75 kg urea ha -1 , N 4 = 100 kg urea ha -1 . The experiment was laid out in split-plot design having three replications. Leaf clipping, levels of nitrogen fertilizer and their interaction had significant influence on growth, yield and yield components of mungbean. The tallest plant(28.97, 44.97 and 45.55cm at 30, 45 and 60 DAS, respectively),the highest pod length (9.06 cm), pods plant -1 (10.67), seeds pod

(12.07), maximum weight of 1000-seed (47.64g), highest seed yield (1.34 t ha 1 ), harvest index (37.14%) were obtained from 50 kg urea ha -1 along with leaf clipping (removal of leaves having no inflorescence) while the lowest from control treatment. 50 kg urea ha -1 and removal of leaves (leaves having no inflorescence) could be an optimum arrangement of mungbean for its optimum yield. -1 -
