Crop Summary
Good early-season conditions resulted in good stands and fast early growth. Severe drought stress during May limited vegetative development and plant height. However, June and July rainfall was more plentiful than other test sites. Thus, corn yielded well considering this year's severe drought. Corn earworms were present at this site.
