Soybean yield and yield component response to plant density in narrow row systems

摘要: Soybean (Glycine max) yield is responsive to changes in plant population and row spacing under dryland conditions. seeding rate recommendations many states were developed prior the release of herbicide tolerant varieties when soybean seed costs lower. As a result, are high, performance at low densities narrow rows needs be reevaluated. This study was conducted evaluate response density row, drilled systems (7.5 15 in) effects on components. The six environments with optimum populations ranging from 80 000 140 plants acre. two components responsible for optimization pods increased, decreased steadily; however, not reduced either year by loss because acre increased as increased. rates each below 150 160 normally recommended region. both years did adversely affect might useful reducing input production.
