Soybean yield in different plant populations, spacings, and irrigation periods

Abstract

The study reported herein was designed to determine the effect of plant population and spacing between rows on yield components and yield per plant of soybean under irrigation in different development stages. Irrigation during vegetative and flowering periods increased the hundred-seed weights. The number of pods per plant was higher in the population of 250,000 plants/ha, but there was no difference between the population of 350,000 and 450,000 plants/ha. The final number of plants per area, seed yield per plant, number of pods per plant and number of seeds per pod were decreased with increased row spacings.
