 Abstract

An experiment was conducted to study the effect of different plant populations on growth and yield of soybean cv pb-1 (Shohag) comprising five population densities; viz.20, 30, 40, 50 and 60 plants m-2. Results revealed that plant height increased with increasing plant density. Contrary to that the number of leaves, root length, number of nodules, total dry matter production plant-1 and absolute growth rate (mg plant-1 day-1) decreased with increasing plant density. The highest number of branches, nodules, leaves plant-1 and yield contributing characters such as number of pods plant-1, seeds pod-1 and seed yield plant-1 were found at the population of 20 plantsm-2. The highest seed yield (2.81 t ha-1) was recorded at 50 plants m-2 and the lowest was recorded in the lowest population density of 20 plants m-2.

Key words: Soybean, Plant density
