545. Auld, D.L.. 1979. Melrose Austrian winter pea.. ID Agr. Expt. Sta. CIS #497.
New variety; 8-12% more yield; more tolerant to Ascochyta foot rot; better winter survival. T: yield, survival, disease resistance.
555. Auld, D.L., G.A. Murray, and R.V. Withers. 1983. Austrian winter peas: a green manure crop for Idaho.. ID Agr. Expt. Sta. CIS #652.
Good % of pea N is from soil; best to plow under right after flowering; Melrose contributed 278 lb/ac of vine N; winter peas produced slightly more biomass than spring peas, but fall peas can be plowed 2 weeks earlier; spring peas accumulated 70 lb N/ac more than winter peas; variable cost of WW-SB-SF = $63/ac, uses 120 lb N/ac; for WW-SB-pea GM = $59/ac, with only 40 lb N/ac; must consider intangible benifits; recommended green manure crop every 3-5 years. T: organic matter yield, nitrogen content, costs.

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.
4703. Murray, G.A. and D.L. Auld. 1980. Spring planted Austrian winter peas.. ID Agr. Expt. Sta. CIS #526.
Variety trial by planting date at 3 locations; seeding rates; lower yield, take longer to mature than spring peas; but net returns may be similar, depending on price. T: variety, yield, seeding rate.
4713. Murray, G.A. and J.B. Swenson. 1984. Intercropping Austrian winter peas and winter cereals for seed.. ID Agr. Expt. Sta. CIS #749.
Peas seeded at 25, 50 and 75% of mixture with winter wheat or barley; both crops harvested on same day; 25% cereal, 75% pea was best mix; less lodging, less disease, 27% yield increase; cereal yields very low; apperently no N advantage to cereal from the pea; less lodging with winter wheat compared to winter barley; better maturity match with barley; LER over 130 with WW(25%) + WP(75%). T: yield, seed size.
5131. Peterson, C.F. and C.E. Lampman. 1955. Austrian peas: a protein supplement for poultry rations.. ID Agr. Expt. Sta. Bull. #231, Combined series.
Contain 25% protein; needs to be supplemented with methionine when feeding; should not exceed 20% of the mash. T: composition, feeding trials.
8522. Kephart, K.D. and G.A. Murray. 1989. Nitrogen, phosphorus, and moisture effects on acclimation of winter peas.. Can. J. Plant Sci. 69:1119-1128.
Increased residual soil nitrogen and compaction-related waterlogging problems may relate to observed reductions in Austrian winter pea winter survival by influencing cold tolerance development. Increased nitrogen reduced survival, while phosphorus had no influence. Higher moisture was correlated with higher lethal temperatures.
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.
