Glyphosate Resistance in Soybeans

Many weeds have developed glyphosate resistance in the past few years.

Winter Wheat Planting Date Is Important

A five year study conducted in southwestern South Dakota evaluating seven winter wheat varieties over four planting dates from September 15 to November 1 showed that delayed planting decreases yields. The results determined that planting mid September to the first of October consistently had the highest grain yield over the duration of the experiment.
