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.

5725. Rasmussen, V.P. and R.L. Newhall. 1989. High residue conservation tillage increases soil moisture and profits. IN: Utah Agricultural Statistics, 1989. p. 121-124. Utah Agricultural Statistics Service, Salt Lake City, UT.
Three years of data are reported for several locations comparing a number of consevation tillage and cropping systems. The no-till and chemical fallow were better both for conserving soil and moisture, and generated the highest net returns. The chem fallow conserved about 1-2 inches of soil moisture. Erosion under the no-till chem fallow ranged from 1-5 T/ac compared to 17-30 T/ac with conventional tillage. The study included tests of continuous cropping, but more years are needed to make an economic comparison.

11037. Anon.. 1990. Annual production of spring wheat in Montana and the Columbia Basin.. Bumper Times Special Report, Spokane, WA. 1/31/90, p. 6..
In Montana, annual minimum till spring wheat produced the highest net returns compared to other summer fallow and winter wheat/spring wheat rotations. No-till continuous wheat produced the highest gross returns, but chemical costs reduced net returns. A farmer near Walla Walla, WA, had compared annual spring wheat to winter wheat-fallow. The annual system grossed $350/ac more than the crop-fallow system over five years. In the annual system, fields are swept after harvest and rodweeded in the fall to avoid the "green bridge." Fields are sprayed with Roundup and seeded to spring wheat as early as possible using a no-till drill. This often is in February. Average rainfall is 9".

11308. Coutts, G.R. and R.K. Smith. 1991. Zero Tillage Production Manual.. Manitoba-North Dakota Zero Tillage Farmers Association, Brandon, Manitoba.
The manual contains a mix of research results and grower experience with no-till management in the Northern Plains. A calendar of operations is included. In a four-year Manitoba study, average net returns per acre for no-till and minimum till were 130% and 77% higher, respectively, compared to conventional tillage.
