5406. Premier Edible Oils Corp.. 1990. Spring Canola Production Guide. Premier Edible Oils Corp., P.O. Box 83599, Portland, OR 97203.
Premier Oils is one of the major oilseed companies in the region, and they are interested in expanded canola production. Canola refers to rapeseed varieties that have both high quality edible oil and oil cake for animal feed. Erucic acid must be less than 2%, and glucosinolate content must be <30 umoles/g seed. The animal feed can contain 38% protein. Oil content of the seed ranges from 41-44%. A bushel weighs 50 lb. Avoid seeding canola more than one year in four on a given field. Watch for herbicide carryover from Glean, Finesse, Assert, or any triazines. Plant canola from mid to late March, about the same time as spring grain. Use about 7-8 lb/ac seed. Row spacing can range from 6-14". Treflan (preplant incorporated) is the only registered herbicide. Volunteer canola is easily controlled. Disease problems have been minor, but sclerotinia and black leg can be serious under humid conditions. Buy only certified, treated seed. Insect pests are flea beetle, seed pod weevil, and cabbage aphids. Avoid late plantings and rotate with non-host crops to help prevent insect problems. Under dryland conditions, spring canola requires 60-75 lb N/ac. P requirements are similar to winter wheat, and soil testing <10 ppm P may require 30-50 lb/ac. Use 25-50 lb K/ac on K deficient soils. Use 20-25 lb S/ac on soils with <4ppm S. If boron levels are <0.5 ppm, apply 2 lb/ac. Canola tolerates pH from 5.5-8.2, and does not like salinity above EC 4.2. The crop requires about 90-110 days to mature. All harvest and handling equipment should be checked for small cracks as significant seed loss can occur. Premier Oils is currently contracting for spring canola. Production budget - yield 1500 lb/ac x value $0.105/lb = gross $157/ac. Variable costs = 64.50/ac. Net returns to management = $93/ac. Breakeven yield = 614 lb/ac.

6429. Smith, H.A., C. Rust, D. Baldridge, and K. Laughlin. 1989. Rapeseed (including canola): a Montana specialty crop.. MSU Extensio Service Montguide MT 8908.
Describes production of rapeseed for oil in Montana. Rape is less drought resistant than cereal grains and uses more water. Because of disease and pest problems, rape should not be grown on the same land more often than every 4 years. It also should not be grown in close rotation with potatoes, sunflower, field beans, field peas,mustard, or other crucifers. A production budget indicates net returns of $6/ac.

8234. Peterson, C.L., D.L. Auld, and R.A. Korus. 1988. Use of vegetable oil as a fuel in time of emergency.. ID Agr. Expt. Sta. Misc. Series No. 111.
Vegetable oil can be used as a substitute for diesel in emergencies. Engine damage and poor performance are possible consequences, though. Descriptions of the potential problems are included. Transesterification makes the vegetable oils more similar in viscosity to diesel, an important step. The brochure details on-farm ester production with rapeseed oil.

10049. Kephart, K.D., G.A. Murray and D.L. Auld. . Alternate crops for dryland production systems in Northern Idaho.. ID Agr. Expt. Sta. Contribution 88762, Moscow, ID..
Increased interest in low-cost input management practices and changes to conservation-oriented government programs are providing incentive for farmers to diversify rotation schemes. However, a lack of commercially viable alternate crops has restricted the number of options available to northern Idaho farmers. This paper lists the results of 10 years of alternate crop experiments into four groups. 1) Species offering no production potential are grain sorghum, quinoa, and soybeans. 2) Crops with limited production potential are meadowfoam, mustard and spring rapeseed, lupines, faba beans, flax, and crambe. 3) Commercialized crops with limited production potential are buckwheat, safflower, sunflowers, and chickpeas. 4) Commercialized crops with unlimited production potential are winter peas and winter rapeseed. Tables 2 and 3 summarize planting requirements and erosion control potential for many of these crops.
