Influence of Cultural Practices on Incidence of Common Rootrot in Wheat in Saskatchewan

Mouldboard ploughing of stubble land in preparation for a second consecutive wheat crop was compared with surface tillage for effect on common rootrot and yield in a study at the Experimental Farm, Swift Current, Sask., during the years 1951–58. Ploughing was found to be effective in reducing the incidence of rootrot in the seedling stage. As the season advanced increasing numbers of plants became infected and by maturity of the crop differences between ploughing and surface tillage frequently had disappeared. In general, yields were not significantly increased by ploughing.
