After Cultivating a field, a player can freely choose to sow the seeds of six different types of grain or vegetables that they so please. Five of these plants have been seen and used before in the Farming Simulator Series, including that of Wheat, Corn, Canola, sugar beet and Potatoes. Some of these items will be used on the Livestock you keep on your farm, while others can be brought into town and sold for a profit. The newest grain added to Farming Simulator 18 is the sunflower, which can also be sold for some extra money.
Always remember to sow only as much as you can reap in a timely manner. If a ripe grain or vegetable is not harvested in time, it will begin to rot and will be deemed a lost.
