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.

5954. Rosell, R.A., R. Martinez, K. Sommer and R. Miranda. 1982. Relationship of crop rotation and nitrogen availability for wheat in semiarid Argentina.. Plant Nutrition 2:551.
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.
