The effect of spacing, plant population and irrigation on soybean seed yield

Abstract

The study reported herein was designed to determine the effect of irrigation in the different development stages, plant population, spacing between rows and their interaction on soybean seed yield. The irrigation did not effect significantly on seed yield under the field conditions of humidity of the plots studied. Seed yield was lower in the population of 350.000 than in the population of 250.000 and 450.000 plants per hectare. The seed yield per area was decreased with the increased spacing between rows.
