Wheat responses to levels, sources and times of application of nitrogen.

Abstract

Trial 90M055 Associated work: 90NO112, 105,104.111, 90MO53, 54,56 Location: Dandaragan This project characterizes the dynamics of nitrogen supply to a wheat crop at each of the sites on which various methods of making fertilizer recommendation were tested. It supposedly provides the optimum nitrogen fertilizer regime as well as detailed information on nitrogen supply and demand so that results can be made transferable to other situations. Trial 90MO56 Related trials: 90NO104, 105, 111, 112; 90MO53, 54,55 Tactical nitrogen application for wheat Location: Danaragan This project compares tactical and strategic methods for determining nitrogen requirements of wheat. The tactical methods depend on updating estimates of yield potential and nitrogen status of the crop as the season progresses
