The Rural Voice, 1983-07, Page 18Canola country Canola is catching on in some of the cooler counties. Now with a crushing plant a little closer, canola may be a good cash crop. Topas is a canola variety from Sweden. Six metric tonnes were brought into the country under special license. PG. 16 THE RURAL VOICE, JULY 1983 by Sheila Gunby If a farmer plants five pounds of canola seed on an acre of land, he'll have up to one metric tonne of seed in three months. The seed production from 200,000 acres will take care of one year's crush at the new canola processing plant recently opened in Hamilton. That's the target for 1990. Canada Packers Inc. has been crushing soybean oil seed at this location for forty years. The new canola plant has just been built. The plant will buy all their seed requirements in Canada. At the present time, most of the seed comes from the Prairies but eventually, all the seed requirements will be grown in Ontario. Several Bruce county farmers were present at the official opening because they are interested in canola production or because they have already planted it for the first time this year. Mac Bolton, ag. rep. for Bruce county says he'd make a wild guess at 2,000 acres of canola in Bruce this year. Bruce county has the heavier soil and cool region conducive to growing canola. "It's grown over in Grey too," he says, "where it's higher and colder, areas like Dundalk." Canola has also yielded well in trials at New Liskeard. Tower and Topas are two varieties he hears a lot about. Bolton says canola is nearly as expensive to grow as corn. "It needs the same nitrogen requirements, Treflan for weeds and Furadan for insects. You'll probably have to go over it again in the summer to catch the Diamondback moth. It's a crop that is not without problems." Canola is Canada's major oilseed crop. It's rapeseed, low in erucic acid (less than 5 per cent) and glucosinolates (less than three milligrams per gram of oil -free meal). The new canola varieties have been bred for low erucic acid content as this acid has been linked with heart abnormalities, according to laboratory studies. Low glucosinolates, studies at U. of G. indicate, makes the meal less likely to cause goiter and organ abnor- malities in livestock and improves feed efficiency as well. Canola is a cool season crop. If planted early in the season, weeds are not a problem. With later plantings, chemical weed control measures are needed. One of the worst weed problems is wild mustard. It can make or break a crop. If more than five per cent wild mustard seed is present, the canola cannot be used for processing. Bolton says there's a new triazine resistant variety being developed to counteract this problem. Current research at Guelph is directed toward the development of varieties tolerant to triazine herbicides such as atrazine or Bladex. Canola is highly susceptible to 2, 4-D herbicides. Clean seed must be used and at least a four year rotation, including cereals and/or corn. Canola should be swathed when about 25 per cent of the seeds in pods from the middle portion of the plant have changed colour from green to red to brown. At this stage, pods are still quite green. Swath- ing too early will reduce grade, yield and the amount of oil in the seeds, while later swathing will result in excessive shatter- ing, according to "Spring Canola in Ontario" a fact -sheet published by OMAF. "It's a stiff crop," says Bolton, "but it does have an advantage of drying quite readily in the field." Arnold Storey, Topnotch, at Milverton says canola production is increasing rapidly. "There were about 4,000 acres in Ontario last year. This year, there will be about 20,000." In Bruce county, he says, it has multiplied as much or more than other counties. It's the lower heat units in Bruce and the northern areas that enables farmers there to grow better canola. Southern counties like Middlesex are certainly not as suitable for this crop. Out-of-pocket expenses, that is, seed, insecticide, fertilizer and weed control, says Storey, are around $60. "The saving is in the seed; it costs less than corn." According to Storey, canola is not easy to store; the fine seeds make air -flow- through a problem. It should not be combined over 11 per cent moisture as it is hard to control heating. Hermann Weller, from the Hanover area is growing winter canola for the first time, just north of Lucknow. Seventy-five acres (in full bloom mid-June) is a double
