Abstract

Crops included in this guide are winter wheat, winter barley, and triticale. You may receive this guide in the mail or through the University of Nebraska Extension network. The data and other information this guide is can be found at our web site: http://cropwatch.unl.edu/varietytest/ and http://www.unl.edu/ncia. Additional information is available at the wheat variety virtual tour web site http://cropwatch.unl.edu/wheat/virtual or the winter wheat variety selection tool page http:// citnews.unl.edu/winter_wheat_tool/index.shtml. The last season was hard on Nebraska winter wheat. Emergence was poor in the west due to dry conditions. On the other hand, some plots in the east had to be replanted due to plot washout from heavy rain after sowing (6 inches in one day!). Elsewhere, it was moist soil conditions at planting for the majority of the locations. Freezing temperatures and snow in early May significantly damaged crop stands in the Panhandle. Strip leaf rust with intensities up to 100 foliage cover and Fusarium head blight disease with varying intensities were observed across the state. Disease score of varieties for the season is shown (where available) at http://cropwatch.unl.edu/varietytest. Severity of strip rust was high in the east and strip rust severity dropped moving north and west. Rainfed plots in Sheridan County were lost to hail damage. Test plots at both irrigated counties, Chase and Box Butte, were lots to the elements. Other additional challenges to the winter wheat crop in 2015 included wet and cool growing conditions at stem elongation, dry conditions at grain filling, and some insect pest problems in the west. Yield and quality parameters were very poor for most of the test plots when compared to the earlier years. Please exercise caution in using this year’s data when advising producers which cultivar to grow.
