Effects of Rainfall and Temperature Interactions During the Growing Season on Corn Yield1
- E. C. A. Runge2
Maximum daily temperatures and rainfall were found to have a large effect on corn yield from 25 days before to 15 days after anthesis. This corresponds to the average calendar interval of June 30 through August 8 at Urbana. The maximum effect of temperature and rainfall on corn yield occurs approximately one week before anthesis and remains at a high level one week to either side of the maximum. The models solved in this investigation indicate that high temperatures (maximum daily temperatures between 32.2 and 37.8 C or 90 and 100 F) can be beneficial to corn yield if moisture available to the corn plant is adequate.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
