Synopsis Yields of wheat were lower in 4 of 7 experiments for fall application of N than for topdressings in the spring. In 3 long‐time rotation experiments, 20 to 23% of the deviations of yields from the linear regression of yields on years could be attributed to winter rainfall. These results indicate that the major portion of N for wheat should be topdressed in the spring under Kentucky climatic conditions.
