MOSCOW, Idaho (AP) — Agricultural experts say the current heat wave can have a negative impact on farmer's crops.

The Moscow-Pullman Daily News reports  temperatures reached over 100 degrees this past weekend. According to the National Weather Service, the highs are expected to be 96 degrees in Moscow and Pullman on Thursday.

A regional specialist with Washington State University's agricultural program, Ryan Higgenbotham, says less moisture in the air can cause kernels to shrivel up. He says barley could be sold at a discount and growers may have to choose varieties of wheat that mature earlier.

Extended periods of heat can reduce the yields of significant crops, including wheat, barley and canola.

Growers have had to fight continuous battles this year as a result of a warmer winter and a dryer-than-normal spring.
