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.

A sequence of small grains, annual natural pasture with grazing and a short (3 months) summer-fall fallowing showed low productivity when compared with a sequence of continuous grain with a long (6 months) fallowing. Wheat yields, number of ears per surface area and total nitrogen uptake were two times higher with long fallowing. Fertilizers are rarely used. Long-term average yields are in the order of 1.2 tons per hectare.
