A field experiment was conducted to determine the influence of population density and planting configuration on dry matter allocation and yield performance of mungbean. The experiment was conducted with six levels of population densities (10, 20, 30, 40, 50 and 60 plants m-2 ) each at three levels of configuration (1:1, 1:2.5 and 1:5 rectangularity). Accumulation and distribution of dry matter to different components of plants were determined. At maturity, grain yield and yield contributing characters were recorded. Population density decreased plant size, but the effect was offset when converted to per unit area basis. Seed yield per plant decreased progressively with the increase in planting density. Significant variation in the number of pods per plant and seeds per pod due to differences in population density caused the variation in seed yield. Planting at higher rectangularity (1:5) out yielded other planting configurations. Planting density and configuration caused similar effect on harvest index.
