Madrid yellow, and Willamette white are recommended for general production and utilization in Wash. T: Date of flowering of varieties. Comparative first and second season heights.

3481. Kaiser, V.G. and A.W. Jacklin. 1939. Annual progress report for field test "effect of cropping systems".. USDA-SCS.
Better sweetclover stands when seeded alone or with grass; peas better than cereals; hi (>10 lb/ac) seeding rate leads to better stands; best seeding date April 10-May 7; more weeds in second year when grown with companion crop; sweetclover/grass mix gave greater wheat yield increase than SC alone, also had less erosion; excellent thorough study. T: Yield, erosion X agronomic management.

6228. Siddoway, F.H. and H.C. McKay. 1962. Tillage of sweetclover under dryland conditions.. ID Agr. Ext. Service Bull. #388 Combined Series.
Sweetclover used in 2 systems: spring grain - fallow (limited growing season, precip>14"); winter grain - fallow (precip <14", growing season adequate); 3-8 lb/ac biennial Madrid sweetclover; less weed growth after sweetclover kill than on summerfallow after wheat; sweep tillage worked well in dry years; moldboard plow was the most consistent kill; sweep left about 35% of sweetclover residue on surface; higher soil nitrates after moldboard plow; no signficant effect on soil moisture; yield correlated to soil moisture; yields 16-18 bu/ac; no control plots. T: nitrogen, soil moisture, wheat yield.
