3098. Swanson, Guy. 1990. Annual production of spring wheat in Montana and the Columbia Basin. Bumper Times special edition, Jan. 31, 1990; p. 6; S. 4305 University Rd., Spokane, WA 99206.
Minimum till continuous spring wheat produced the highest net returns in a Montana study. The cost of Roundup reduced net returns in no-till, although no-till had the highest gross returns. John Rae, a WA farmer, has compared continuous no-till spring wheat with his normal winter wheat-fallow system. The continuous system has produced $350/ac more gross returns over five years in his 9" rainfall area.
