2033. Fowler, D.B. and J. Brydon. 1989. No-till winter wheat production on the Canadian Prairies: timing of nitrogen fertilization.. Agron. J. 81:817-825.
Tested the effect of timing of a broadcast application of ammonium sulfate on grain and protein yield and protein concentration. Lower grain yield, grain protein yield and grain protein concentration were attributed to loss of fall applied N in four trials. Increased grain protein concentration was often associated with delayed N availability. Reduced grain and grain protein yield, and increased grain protein concentration were observed for fall and early spring N applications in trials that experienced favorable spring weather followed by a prolonged drought.
