Illinois farmers say the rainy and hot weather extremes this summer have affected their crops.

Emerson Nafziger is a crop production specialist at the University of Illinois. He says crop yield will vary widely across Illinois. He cited varying weather, from 19 inches of rain in Galena to dry weather in central Illinois.

Farming experts say hot weather in parts of Illinois have hurt the corn crop, while inches and inches of rain in other areas could mean near-record yields.

Union County farmer Mark Eddleman says late-planted corn and soybeans need rain and cooler weather to be successful.

Peoria County Farm Bureau manager Patrick Kirchhofer says July's high temperatures took a toll on corn, likely reducing yields. Peoria County corn yields are forecast at 150 to 180 bushels an acre.
