Are nitrogen and sulfur recommendations for barley similar to those for wheat?
They are similar in that the goal should be to promote fall and early spring tillers, which represent most of the crop’s yield potential. Accordingly, if tiller population is low by the time the barley goes dormant, the crop should benefit from an application of ammonium sulfate as soon as it starts greening up. Nevertheless, nitrogen needs for barley are lower than for wheat:
Barley: 120 to 140 pounds per acre for a 100 bushel-per-acre crop
Wheat: 140 to 160 pounds per acre for a 90 bushel-per-acre crop
