Crop Yields Decline under Higher Temperatures

Crop Yields Decline under Higher Temperatures

Crop yields are very sensitive to temperature and rainfall. They are especially sensitive to high temperatures during the pollination and grain filling period. For example, corn (left) and soybean (right) harvests in Illinois and Indiana, two major producers, were lower in years with average maximum summer (June, July, and August) temperatures higher than the average from 1980 to 2007. Most years with below-average yields are both warmer and drier than normal.9c3f871b-4405-4d6b-bf56-439b678f7025,3dccc6c2-6a42-49ef-990b-853a220a28f4 There is high correlation between warm and dry conditions during Midwest summers9f976ed6-c1dd-437d-aaf9-062bca25bbc9 due to similar meteorological conditions and drought-caused changes.2ad99c76-b8df-4faa-b52e-095bb4094cab (Figure source: Mishra and Cherkauer 20109c3f871b-4405-4d6b-bf56-439b678f7025).
