3955. Mahler, R.L. and D.L. Auld. 1989. Evaluation of the green manure potential of Austrian winter peas in northern Idaho.. Agron. J. 81:258-264.
Austrian winter peas were evaluated as a green manure (GM) or seed pea (SP) crop, along with soil N levels, and subsequent yields of winter wheat (WW) and spring barley (SB). Four rotations were tested: GM-WW-SB; SP-WW-SB; SB-WW-SP; SF-WW-SB. Average N fertilizer equivalent values of 94, 75, and 68 kg/ha were provided by GM, SP, and SF (fallow) respectively, to the following wheat crop. Yield differences due to crop rotation or N fertilization rate were not observed in the third year of the cropping sequence. Austrian winter peas used as either a GM or SP provided more inorganic N than SF or SB. Although cereal crop yields were comparable, the SP-WW-SB was more profitable than GM-WW-SB or SF-WW-SB, due to the extra harvested crop.

8763. Smith, Larry. n.d.. An evaluation of green manure plowdown systems in Nex Perce County, Idaho.. unpublished results from Cooperative Extension, 1239 Idaho St., Lewiston, ID 83501.
Three growers evaluated the nitrogen benefits and economics of their use of green manure legumes prior to winter wheat production. Two farmers used Austrain winter pea, and one used a sweetclover/red clover mix. Soil tests at various stages of production indicated an increase in available N (0-3') after green manure plowdown of 60-200 lb/ac. The cost of the green manure ranged from $15-27/ac. Clover appeared to produce the most N (191 lb/ac) while winter peas returned 62-116 lb/ac. Landlords did not charge rent for the green manure year, which helped the economic viability. Residual N values indicated that fertilizer N could have been greatly reduced or eliminated for the winter wheat after plowdown. Net returns for the two-year period ranged from $95-215/ac.
