Abstract
The effects of soil management systems and winter crop rotation on wheat yi eld and root diseases were assessed. No-tillage, minimum tillage, conventio nal tillage using a disc plow plus disc harrow, and tillage using a moldboa rd plow plus disc harrow were the soil managements compared. In crop rotati on, three systems were used:system I(wheat/soybean), system II(wheat/soybea n and common vetch/corn or sorghum), and system III (wheat/soybean, black o ats or white oats/soybean, and common vetch/corn or sorghum). A randomized block experimental design, with split-plots and three replicates, was used. The main plots were formed by the soil management systems, while the split -plots consisted of crop rotation systems. Yield of wheat grown under no-ti llage and minimum tillage was higher than the yield of wheat grown under co nventional soil tillage using either disc plow or moldboard plow. Crop rota tion was efficient in reducing root diseases and in increasing wheat yield.
