Soybean Resources

Soybeans are planted on more acres than any other row crop in Tennessee, with over one million acres grown annually (production map).  Each year, soybeans rank in the top three for cash receipts for row crops.  In 2018, Tennessee harvested nearly 47 bushels per acre across almost 1.7 million acres.

Most soybeans are grown in west and central Tennessee counties without benefit of irrigation and over 80% are grown in a no-till or conservation tillage system.  Approximately 30% of soybean acres are double cropped after wheat.  Group IV varieties are predominant, while less than a third of acres are maturity Group III and V varieties. Yields are heavily dependent on rainfall.  In recent years, herbicide technologies have played an important role in the management of glyphosate and PPO resistant palmer pigweed.
