Off-Station Spring Wheat Performance Under Fallow in Central Montana (2010)

Abstract

This report evaluates the performance of spring wheat cultivars in fallow near Geraldine. To fit the cooperators change in systems, the trial was established as no-till recrop after winter wheat in a crop-crop-fallow system. The 2010 growing season conditions were generally optimal for spring wheat production. Cooler July weather contributed to good spring wheat yields. While the Geraldine site has typically been fallow in the past it is now in a winter wheat – spring wheat – fallow system. The Geraldine environment provides a good evaluation of both yield potential and sawfly tolerance. Vida, a semi-hollow stem line, has been a consistently high yielder at Geraldine for the past few years along with solid stem lines in Choteau, Corbin, and O'Neal and a low sawfly attraction variety Conan. Vida is intermediate in test weight and protein content. The higher protein content varieties generally are lower yielding and that has been the case at Geraldine with AP604CL and Kelby.
