Abstract
The objectives of this project were to measure corn yield response to nitrogen (N) fertilizer when applied during the V10 corn growth stage, and compare yield and N use efficiency between pre-plant N (PP-N), pre-plant + sensor N (PP+S-N), split N strategy (SNS), and rescue N strategy (RNS). The study was conducted using two crop rotations (corn-soybean and continuous corn) at multiple research farms. In-season applied N was urea treated with Agrotain® .
