Abstract: A field experiment was conducted to determine the influence of population density and planting configuration on allometric relationships in 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. Allometric relationships between stem weight and leaf weight were developed from their respective dry weights. Stem materials per unit leaf weight increased over growth stages. Reproduction enhanced dry matter allocation into stem per unit leaf weight. The magnitude of increase varied greatly with planting density. The ratio of stem weight per leaf weight and leaf weight were linearly correlated. Planting configuration had little effect on the allometric relationship.
