Abstract: The nitrogen management of spring wheat milling cultivars was evaluated in Hartland, NB. Four spring wheat milling cultivars, Grandin, AC Walton, SS Maestro, and Glenlea were subjected to ten nitrogen treatments. The nitrogen treatments ranged from 0 - 150 kg N/ha and were applied at three different growth stages (seeding, GS 30, and GS 39) in increments of 25 or 50 kg N/ha. Mean yields of the four cultivars increased from 3.04 t/ha - 3.80 t/ha, the mean percent protein increased from 11.09 % - 13.04 % and the mean plant height from 98 cm to 102 cm. Both test weight and thousand kernel weight decreased as nitrogen rate increased.
