A new hybrid mustard variety, AAC Hybrid Brown 18, developed by Agriculture Canada, is set to be planted on nearly 30,000 prairie acres, which is about 15 to 20 percent of total brown mustard plantings in Western Canada. This variety is expected to increase yield by 20 percent compared to open pollinated mustard varieties, making it more appealing to growers and processors. The seed is available through three distributors, but demand is high and supplies may be limited. Trials are also being conducted to see if more intensive fertility programs can increase yields further.
