Winter wheat is a common ingredient in bread and all-purpose flour.


Illinois is known for its winter wheat production, which gets planted in the fall and harvested in June and July. After planting, the plant grows a little before going dormant for a while. It starts growing again in late winter.   

In the United States, Illinois ranks third for wheat production with $378,252,000 in production value. Washington, Randolph, and Perry counties produce more winter wheat than any other county in the state. 

Winter wheat is a common ingredient in many food items, making it an essential crop for many. Farmers can also double-crop after harvesting winter wheat, meaning they use the same land to produce multiple crops in one crop year. They can do this by planting soybeans into the wheat stubble. 

4. Hay and Haylage

One of the most valuable crops in Illinois is hay and haulage.


Hay and haylage in Illinois have a $258,129,000 production value, making it one of their most valuable crops. These two kinds of preserved forage differ in how they are preserved, their nutritional value, and their moisture content.   

Haylage gets cut sooner than hay and is left to wilt instead of drying out. Preservation occurs via fermentation, and then the haylage gets baled before being wrapped in layers of plastic to help maintain the moisture content. This process keeps the crop safe from mold and spores. 

On the other hand, farmers don’t harvest hay until sometime between June and August. They preserve it through dehydration during days of sunny weather, which is why it must be harvested later than haylage. The process leads to hay having fewer nutrients and calories than haylage. 

5. Pumpkins

Sweet corn is in season in Illinois from June through October, and its production value is $17,443,000. Farmers start planting multiple early varieties around the estimated frost-free date to provide a continuous supply all summer. Once three or four leaves appear on the seedlings for the first planting, a second planting often occurs and can happen until the beginning of July.  

7. Beans
