Technical Abstract: The yield response of winter wheat to LEPA double-ended-sock, LEPA bubble and overhead spray sprinkler methods was measured at the USDA-Bushland Laboratory with four irrigation amount and two irrigation timing treatments. Irrigation amounts were full irrigation and 0, 33, 67% of full irrigation. Irrigation timing was evaluated by either delaying full irrigation in the early spring or cutting off full irrigation during early grain filling. Wheat yields did not vary significantly among the two LEPA methods and the overhead spray method so yields from the three sprinkler methods were averaged to evaluate the effect of irrigation amount and timing. Wheat yields averaged across the three sprinkler methods increased from 25 bu/ac for dryland to 67 bu/ac for 100% irrigation. Full irrigation with cutoff during early grain filling was efficient with a yield of 57 bu/ac, but with delayed spring irrigation, the yield with the same amount of irrigation water was only 47 bu/ac.
