Nebraska Soybean N Trials — Figure 1. Photos of one site of the Nebraska Extension Soybean Management Field Day research (2013) that compared the effects of several nitrogen treatments on soybeans. Pictured is the zero N control on the left and the 400 lbs/ac split N application on the right. Averaged over four sites the control yielded 73.4 bu/ac and the 400 lbs N averaged 78.9 bu/ac.
