Could rice be the next crop in southern Alberta?

Probably the last place one could imagine growing rice would be southern Alberta, but, as one University of Lethbridge researcher is finding out, it may not be outside the realm of possibility.
Dr. Michele Konschuh, a research associate in the Department of Biological Sciences, in collaboration with Galaxy Ag Ventures and Farming Smarter Association, is examining the potential for rice to be a value-added crop in this region. Rice is a gluten-free food staple that provides valuable by-products like rice starch, protein and oil. Galaxy Ag Ventures is a Calgary-based company involved in strategic investment and product development in agri-foods. Farming Smarter is a farmer-led, not-for-profit organization based in Lethbridge dedicated to driving innovation at the farm level.
“One of the big questions is how you are going to grow rice in Alberta,” says Konschuh. “I wasn’t all that confident when they first approached me, but they did bring some technology from Korea called seed film cultivation (SFC). It’s essentially a biodegradable plastic layer that they attach the seed to and lay over moist soil.”
Konschuh explains the SFC helps warm the soil and prevent moisture loss, as well as prevent weeds from taking root. Alberta’s climate tends to be cold and dry with a short growing season. However, as rice is grown in some mountainous regions, some varieties are adapted to lower temperatures and shorter seasons. Also problematic are Alberta’s long summer days because rice likes shorter days to flower. And irrigation will be needed; Konschuh says rice needs about the same amount of water as a potato crop.
After a short-term pilot project this spring, the experiment has now moved to the field. With Galaxy Ag providing the funding and Farmer Smarter the land, technological expertise and equipment, a ULethbridge undergraduate student funded through Mitacs was hired to work on the project. Three methods for planting were used: the SFC technique, transplanting plants grown in a greenhouse, and direct seeding. The researchers also opted to try two types of irrigation: overhead pivot and subsurface drip.
“All three methods of planting have been successful so far,” she says. “What we don’t know is if we can get them all the way to rice seed production and maturation by fall. This is really early steps and the nice thing is that both B.C. and Ontario have successfully grown rice. So, we know rice can grow in Canada; what we don’t know is if rice can grow in Alberta because our conditions are a little bit different.”
