Recent high temperatures occurred at a particularly critical period for the Kansas corn crop. Temperatures last week were unfavorable for a significant portion of Kansas. Heat stress during critical stages could lead to yield reductions.

Heat stress will have more of an impact on corn during the reproductive stage of growth when combined with drought stress. Stress conditions were very severe in parts of central, south central, and southeast Kansas.
