Winter Wheat Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, Fort Benton, Moore, and Winifred (2000)

Abstract

This report evaluates the performance of winter wheat varieties in environments and cropping methods. Dry conditions resulted in lower than average yields at all sites with the exception of Moccasin where re-crop wheat followed barley. Growing season precipitation of 3.9 inches at the Fort Benton site contributed to low yields ranging from 8.8 to 12.6 bu/a. Yields were highest at the Moccasin site ranging from 35.8 to 46.2 bu/a. No yields were recorded at the Denton site due to a plugged opener during seeding that resulted in non-uniform plots. Grain protein was lowest at the Denton site and highest at the Fort Benton site. Although moisture for the 2000 crop season was generally higher than that received the previous year, timing of rainfall contributed to a lower than average yield at most sites. Yields at the Moccasin site met the seven-year average for cultivars grown at that site. Yields at all other sites were well below their ten-year averages as noted in multi-year yield summaries for each site. seeded into spring wheat stubble. The Moccasin trial was seeded into barley stubble. All cultivars had acceptable test weights averaging 61.2 lbs/bu across all sites and all cultivars. Test
