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.
