Until recently, winter wheat nitrogen recommendations were based on research conducted 30 years ago. Production practices have changed significantly, with increased yield potential through the use of better genetics (varieties), and availability of fungicides, and growth regulators. As producers pursue higher wheat yields using improved management techniques, current N recommendations may not be sufficient. This study evaluates the Maximum Economic Rate of Nitrogen (MER-N) under current management regimes. N recommendations have been increased (2012) based on this research. This research continues to validate and fine tune N recommendations with latest genetics and management techniques.
