Tested white lupin adaptability to irrigated and non-irrigated conditions in Colorado. Screened the crop for a number of herbicides, none of which was entirely satisfactory. All damaged or killed the lupins at rates needed to control weeds. Non-irrigated yields were about 30 bu/ac, up to 50 bu/ac with full irrigation. Lupins did not appear to utilize stored soil water at lower depths.
1998. Fletcher, O.S.. 1923. Growing sweetclover in Latah county.. V.Kaiser papers, box 1, folder 66.
Results of a survey of farmers using sweetclover; mostly interested in summer pasture; using biennial white; need firm seedbed, 10-15 lb seed/ac, early spring planting; mixed results with a nurse crop, less winterkill when planted alone; good results from inoculation; 1-2 1/2 T hay/ac the second year; following crops showed yield increase; no problem with weediness; most stock did well on sweetclover, except horses.

Brief summary of legume species grown in the region. Mentions a rotation in the Camas Prairie, ID area of 3 yr alfalfa-WW-SB-AWP. Mentions lupin and chickpea as possible crops in the transition area to substitute for fallow. Mentions sweetclover intercropping with spring barley, with barley yields 85% of normal.

Three tillages were compared for incorporating Austrian winter pea or red clover green manure: moldboard plow plus shallow disk; shallow disk twice; no-till. At each N fertilizer rate, winter wheat yields were slightly higher with reduced tillage than with conventional tillage. A 60 lb/ac N rate substantially increased wheat yields after green manure, while the 120 N rate gave little or no yield increase. With no N fertilizer, the yield of winter wheat after both green manure crops compared favorably with yield of no-till winter wheat after a seed crop of spring peas. Legume N uptake by a following wheat crop was not affected by residue treatment, but recovery of legume N from the soil was about 10% lower with surface application than with soil incorporation. Also, wheat yields after chemically-killed green manures were consistently lower, and could not be fully recovered with fertilizer N. The mechanism of this suppression is not known.
