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.

8252. Auld, D.L., D.R. Brady, and K.A. Mahler. 1989. Rapeseed and canola breeding in North America: The U.S. potential.. 5th Crucifer Genetics Workshop Report No. 4. Genetic Resources Conservation program, U.C., Davis, CA.
Five factors currently limit expanded canola production in the U.S.: farm program, lack of proven varieties, lack of grower education, lack of integration into the oil industry, price fluctuations. Many efforts are underway to develop proven varieties for various parts of the U.S., and these are listed. Also, a table of potential pest considerations is included.

8261. Auld, D.L.. no date. Rapeseed/canola genetics - University of Idaho.. Dept. Plant, Soil,Ent. Sci, Univ. Idaho, Moscow, ID 83843.
Oilseed brassicas currently provide about 15% of the world's edible oil. Products from oilseed brassicas include canola oil, specialty edible oils, industrial polymers, biological fungicides, and clean fuels.

10978. Anon.. 1990. New Jersey firm wants Palouse canola seed.. Palouse Living, 1/16/90, Pullman, WA..
DNAP wants to expand production of spring canola for processing at Idaho Falls. Contracts will be available to growers. Fields need to be at least a mile from other rape or canola fields to avoid contamination.
