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.

Saskatchewan researchers tested several legumes as possible fallow replacements. Inoculation greatly improved growth and water use efficiency of the legumes, with an average of 2000 lb/ac dry matter and water use efficiency of 1490 lb H2O/lb DM. Legumes fixed an average of 44 lb N/ac. Chickling vetch performed the best, but since wheat yields were similar after all species, Indianhead lentil proved to be the most economic choice.
