Summary

Summary

Average corn yield in 2019 was increased by 14 bu/a with knife application of pre-plant nitrogen (N) fertilizer compared with broadcast application. Applying N more than doubled yield of corn grown without N. Applying side-dress N increased yields compared to yields obtained with only pre-plant applications
