Record U.S. Canola Production in 2022

By Angela Dansby and Dale Thorenson

U.S. canola had record production this year, up a whopping 45 percent from 2021, according to the Oct. 12 crop report from the U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS). Nearly 2.2 million acres were harvested with an average yield of 1,826 pounds per acre, resulting in 3.95 billion pounds of canola.

Looking back 30 years at NASS records, U.S. canola production has grown in spite of ebbs and flows, increasing more than 95 percent from 191 million pounds to nearly 4 billion. Yield has been erratic with several big dips (2002, 2007, 2012, 2017 and 2021) influenced by Mother Nature, however, production well outpaced yields during those years. More importantly, canola genetic traits have continued to improve, largely driving the 500-pound/acre increase since 1991, when yield was only 1,300 pounds per acre. Read More »

End of a Canola Era at University of Idaho

By Jack Brown, Ph.D.

The University of Idaho (UI) oilseed research group has a long history of agronomic research. It started developing canola cultivars before the crop was approved as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Association in 1985. Read More »

Gene Editing Brings New Canola Traits

By Jim Radtke, Ph.D.

Plant breeding has driven the development of canola as an edible oilseed crop. In the 1960s, Canadian breeders took an industrial oilseed crop called rapeseed and selected for an edible oil profile, significantly reducing erucic acid to create “Canadian oil low acid” (canola) with excellent edible oil quality. But they were not done. Further advancements were made to change the crop into high yielding hybrids and the use of biotechnology (integrating foreign DNA) added resistance to herbicides, allowing for better weed control and crop management.

Weed Control in Canola: Can we Keep up with Weeds?

By Brian Jenks, Ph.D.

It’s now been 24 years since herbicide-tolerant canola was first approved in the United States. The ability to control weeds in canola with post-emergence broadleaf herbicides revolutionized canola production. Prior to 1998, soil-applied herbicides Treflan® and Sonalan® were able to provide decent control for many weeds; however, many canola fields struggled to compete with tough weeds like kochia. With no post-emergence herbicide options other than Stinger®, growers had to save canola for their cleanest fields and hope the crop would outcompete the weeds. Read More »

Straight-Combining vs. Swathing Canola

By Anitha Chirumamilla, Ph.D., and Hans Kandel, Ph.D.

Producers traditionally have swathed rather than straight-combined canola. In recent years, the availability of new pod shatter-resistant varieties has made straight cutting the new trend for canola harvesting. However, both swathing and straight combining have their places based on harvest conditions. Timely straight cutting can save time and money and result in improved canola yields and seed quality (lower harvest moisture, less green seed and higher test weight). Heavier canola stands are better suited for straight combining than thinner stands because of the decreased likelihood of shattering from wind. In the absence of pod shatter tolerance, straight combining has resulted in yield losses of 8 to 54 percent, as reported by the Canola Production Center in Canada. Read More »

Clubroot Incidence and Management in Canola

By Venkata Chapara, Ph.D.

Clubroot disease on canola is caused by Plasmodiophora brassicae, a soil-borne pathogen that moves from field to field on both agricultural and non-agricultural equipment. In simple words, it moves from whatever moves the soil. With an objective to determine the extent of disease spread in North Dakota, clubroot incidence and prevalence has been monitored in annual surveys for six years by examining canola roots for clubs/galls. These surveys have been funded by the Northern Canola Growers Association, Northern Canola Research Program (USDA/NIFA), SBARE and NDCP Product Harmonization Board. Read More »

Small Canola Production in Oregon’s Willamette Valley Yields Big

By Anna Scharf

The Willamette Valley in Oregon encompasses a 150-mile long stretch that runs the lengths of Interstate Highway 5 from Portland to Eugene and east to west from the Cascade Range to the Oregon Coast Range. With numerous waterways and highly fertile soil, this valley is the most agriculturally productive and diversified region of the state. It produces everything from fresh market produce and specialty vegetable seeds to grass and tree seedlings, wine grapes and hazelnuts. Oregon produces over 170 crops statewide and the vast majority of them can be found in the Willamette Valley. Read More »

Organic Canola Production: Challenges and Opportunities for U.S. Farmers

By Brian Caldbeck

Consumer trends in recent years have resulted in retails sales of organic foods in the United States reaching $50 billion in 2020, according to the Organic Trade Association. Despite cooking oils derived from multiple crops, including canola, representing a tiny fraction of these sales, consumer interest in organic canola oil has encouraged the food industry to source organically produced canola from farmers.

Canola Cultivars Progress in North Central Region

Luis del Rio-MendozaBy Luis Del Rio Mendoza, Ph.D.

Through a grant from the National Institute of Food and Agriculture, North Dakota State University (NDSU) worked on improving spring canola varieties and conducted agronomic research on the crop. Nitrogen applications and clubroot management were examined. Read More »
