5705. Rasmussen, P.E., H.P. Collins, and R.W. Smiley. 1989. Long-term management effects on soil productivity and crop yield in semi-arid regions of eastern Oregon.. OR Agr. Expt. Sta. Bulletin 675.
Summary of over 50 years of plot research at Pendleton, OR, with some results from Weston and Moro. Focuses on results from a continuous set of plots at the Pendleton station. Manure maintained highest yields, highest soil organic matter, highest pH compared to other treatments. Nitrogen fertilizer had a more marked effect on water infiltration than various tillage treatments. Green manure systems are generally not economic in the drier areas, due to competition for moisture with wheat, which is the most profitable crop. Legumes can contribute between 40 and 80 lb/ac N to the following crop. Varietal improvement over the past 50 years has been the most significant factor in increasing wheat yields. Burning straw accelerated organic matter losses from the soil and eventually reduced yields. Marginal returns have generally been lower from alternative crops than from wheat.

7221. Veseth, R.. 1989. Small red lentils as a fallow substitute.. STEEP Conservation Farming Update, Spring 1989, p. 15.
Small red lentils may provide a viable cash crop substitute for summer fallow in the 14-18 inch rainfall zone. Yields at Davenport were 1,202 lb/acre an 1988 (a drought year). Red lentils consume little water and would not interfere with subsequent winter wheat seeding. They require no nitrogen fertilizer, can be grown with conservation tillage, and reduce disease incidence in wheat. T: Comparison of yields of small red, large red, and large yellow lentils at Davenport, WA.
