Corn Growth as Affected by Soil Temperature and Mulch1

W. O. Willis, W. E. Larson and D. Kirkham2

Sypnosis: Increases in soil temperature accelerated rate of emergence, rate of growth, and promoted earliness in corn. Corn growth rates approximately followed the Van't Hoff law, the Q10° c. of that law being from 2.0 to 2.8 for the average temperature range tested, 60° to 80° F. Corn yields appeared to increase with increases in soil temperature up to a point and then decreased with further increases in soil temperature. The most favorable soil temperature at the 4-inch depth for corn growth in central Iowa appears to be about 75° F.
