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.
