Winter wheat (Triticum aestivum L.) is grown under both conventional-till and conservation-till systems in the Northern Great Plains. A benefit of sowing winter wheat into standing stubble is the protection the crop receives from trapped snow and the resultant reduction in winter kill. A 5-yr study was conducted at four locations in North Dakota to measure cultivar-by-tiliage interactions for quality parameters of wheat and to determine whether testing under both conventional-till and no-till systems was advantageous. Fourteen hard red winter wheat cultivars were planted during 1984-1985 through 1988-1989 in a Max loam (fine-loamy, mixed, Typic Haploborolls) at both Williston and Minot, in a Svea loam (fine-loamy, mixed, Pachic Udic Haploborolls) at Langdon, and in a Bearden silty clay (fine-silty, frigid, Aeric Calciaquolls) or Gardena silty loam (coarse-silty, mixed, Pachic Udic Haploborolls) at Fargo. Significant cultivar-by-tillage interactions (P < 0.05 or P < 0.01) were obtained for volume weight, protein content, and flour yield when the analysis was restricted to environments in which wheat winter killed. A change in rank order of cultivars was detected only for volume weight. For the other quality parameters measured, evaluation of winter wheats grown in conventional-till and no-till plots resulted in similar relative performance of cultivars.
