The term FARM OUTPUT can be broken down into two crossword solutions: CROP (4 letters) and GRAIN (5 letters). A CROP is a type of plant that is grown and harvested for food, feed, or other commercial use. Grains are small, hard, dry seeds that come from grass-related plants such as wheat, oats, barley, and rye. Both crops and grains are important outputs of farms, as they are used to produce food and feed for humans and animals.
