Abstract
Our objective was to determine if tillage (disk fall and spring, disk fall only, or no tillage) affected rice diseases, plant population density, and yields in a rice monoculture system. Stem rot was the only disease that developed in plots during 1994, and the severity index was the same for all tillage treatments. Diseases did not develop in plots during 1995 and 1996. Tillage treatments did not affect rice plant population or yields. This is the first report on the effects of tillage on stand and yield in a rice monoculture system. A fall‐only tillage system (stale seedbed) may be useful to some rice producers in the central USA because yields are similar to those in a conventional tillage system. Ruts in the field due to harvest equipment could be eliminated by fall tillage, and tillage in the spring would not be necessary prior to planting and application of a burn‐down herbicide.
