Consistently high soybean yields are essential for sustaining profitable soybean production systems in Arkansas. Previous research has shown that delays in irrigation initiation, scheduling, and termination can limit yields and that the effects can vary from season to season and among maturity groups and soil types. Given the substantial investments needed to irrigate soybean fields, identification of practical irrigation scheduling methods that increase the odds for higher yields, profit potential and better seed quality would be in the best interests of Arkansas soybean producers.
