The effect of buckwheat seed storage duration on major indices of the quality was analyzed. Seed collected in 1996 and stored for 30 days (analyzed in 1996), seed stored for one year (analyzed in 1997), seed stored for two years (analyzed in 1998), seed stored for three years (analyzed in 1999) seed stored for four years (analyzed in 2000), seed stored for five years (analyzed in 2001) and seed stored for six years (analyzed in 2002) were investigated. The results of investigation have shown that seed stored up to two years had preserved its good production traits.

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.
