The effects of winter cover crops on root disease and growth of corn and soybeans are ineffectively perceived. A 3-year field explore investigated the impact of winter grain rye and winter camellia (Camellia sativa[L.] Crantz), utilized either in every one of the three years or in rotation with one another, on corn (Zea maysL.) and soybean (Glycine max.[L.] development, root illness, and yield. Corn following a cover crop of camellia had decreased root illness, a lower Pythium population in seed-ling roots, and more prominent development and yields contrasted and corn following a rye cover crop. Camellia and rye cover crops before soybean affected soybean development and advancement, root disease, and yield. Moreover, Pythium clade B populaces were more prominent in corn seedlings after a rye cover crop contrasted and those following a camellia cover crop, though clade F populaces were more prominent on soybean seedlings following a camellia cover crop contrasted and seedlings following a rye cover crop. A colder time of year camellia cover crop developed before corn had more positive consequences for corn seedling development, root illness, and final yield than a colder time of year rye cover crop before corn. Neither one of the covers crop had negative consequences for soybean, and the cover crop in the previous spring had no quantifiable impacts on one or the other corn or soybean
