Much like Corn, Canola is one of the more important Grains that a farmer can grow.due to the implications it holds with Pigs. Again, Pigs need both Canola and Corn (as well as some straw) to make their bedding. Without having proper bedding, Pigs can not and will not bred with other pigs. The money to be made from both Canola and the Livestock of bred Pigs is huge for any farmer, making this type of grain as key as any other a player can plant.
