The results of two-year investigations of buckwheat raised in agroecological conditions of South Banat (Pančevo) and West Serbia (Gorobilje) are presented in the paper. Based on the obtained investigation data, we confirm the hypothesis that buckwheat is a plant suited to more humid regions, since we have determined higher yield of the plant on locations with higher precipitation amount. During 1999, the yield of buckwheat was higher at the location in Pančevo and the next year at the location in Gorobilje.
