Abstract: Mungbean variety NM-96 was planted to see the effect of different planting densities on yield and yield components, crop was planted at 15, 30 and 45 cm single row strips with 5, 10 and 15 cm plant spacings. Maximum numbers of branches per plant was obtained with plant spacings 15 and 10 cm, respectively, while minimum with 5 cm. Maximum number of pods per plant was observed with the crop sown at 45 cm row spacing against minimum at 15 cm. Maximum number of seeds per pod was observed with a row x plant spacing combination at 45 x 15 cm against minimum at 15 x 5 cm. Maximum seed yield was obtained with the combination of row x plant spacings at 30 x 10 cm as compared to the other combinations while minimum seed yield was observed when row x plant spacing kept at 45 x 15 cm. Maximum harvest index was obtained with row x plant spacings at 45 x 15 cm against harvest index when row x plant spacings were maintained at 15 x 5 cm.
