Seed growth rate, seed filling period and yield responses of soybean (Glycine max) to plant densities at specific reproductive growth stages

There is limited information on the seed growth parameters to different plant densities and their effect on plant yield. The purpose of this study was to investigate the effect of plant population density on changes of rate and duration of seed growth at specific reproductive growth stages, and to e...
