The Agronomic Performance of Spring Wheat Varieties in 2007 Central Montana Trials

Abstract

At the start of the 2007 growing season the spring wheat yield potential looked very good. Mid-late April seeding conditions were generally good. Early May precipitation was much above average. However, in late May through July precipitation levels fell below average and summer temperatures were above average. The summer growing conditions caused substantial stress to late maturing spring crops including spring wheat. Grain test weight is the primary spring wheat yield component affected by late season stress.
