Average yields are about 3 tonnes per hectare for hard red spring wheat, 6.9 tonnes per hectare for winter wheat, 4.02 tonnes per hectare for barley, and 2.3 tonnes per acre for canola. However, yields will vary somewhat from these figures in different areas of the province due to soil types and annual rainfall amounts. Most of the grain and oilseeds grown in Manitoba are transported overland by rail, with in excess of 65% of the entire crop being exported.
