The effect of rotation and tillage on foot-rot of wheat in Kansas, 1920-1924
1924
Sewell, M.C. | Melchers, L.E.
Foot rot of wheat has been present during the period 1921-1924 in the tillage and rotation experiments of the Kansas agricultural experiment station. Wheat grown in rotation has not been damaged by foot rot. September plowing, with or without previous disking, did not favor the development of this disease. Foot rot of wheat may occur in fields cropped continuously to wheat where the best tillage method for wheat production is practiced. The continuity of long time experiments based on continuous wheat culture may be interrupted by foot rot.
