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.
7786. Engel, R., L.E. Welty, R. Lockerman, J. Bergman, G. Kushnak, L. Prestbye, and J. Sims. 1987. Annual legumes and cereal grain rotations in Montana.. Montana AgResearch 4(3):1-4.
Montana researchers examined the performance of several grain legumes (dry pea, chickpea, lentil) and their effect on a subsequent barley crop. Dry pea production was the highest. A subsequent barley crop rsponded to added N fertilizer at three out of six sites. Barley yields following legumes were generally equal to or greater than yields following fallow. The annual legumes contributed to soil N and reduced the fertilizer N needed to reach maximum yield by 40-55 lb N/ac when compared to recrop barley. This translated into savings of $10-14/ac for fertilizer N.

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".
