Figure 1. Final soybean stand count was not necessarily an indicator of yield in this 2017 study of the effects of late-season (R3) nitrogen application in soybean. The Lincoln County plot (left) had a final stand count of 72,000 plants per acre and yielded 72.7-73 bu/ac. The Perkins County plot (right) had a final stand count of 161,000 plants per acre and yielded 74.4-77 bu/ac.
