Abstract
The experiment was conducted at Sher-e-Bangla Agricultural University, DhakaBangladesh during kharif-I season (March to July, 2017) to study the effect offertilizer and spacing on the morphological characteristics, yield contributingcharacters, yield and seed quality of mungbean. The experiment consisted of Factor

plot and spacing in the sub-plots. The results indicated significant variations in plantheight, number of leaves plant
