We investigated the effect of N-fertilization, sowing rates and soil-climatic conditions on yield and yield components of linseed varieties Atalante and Szegedi-30. Field experiments were carried out from 1994 to 1998 at two different localities in the sugarbeet production region. The seed yield was significantly affected by the site, year, N fertilization, sowing rate and variety. The yields of seed dry matter varied from 0.43 t/ha to 2.76 t/ha. N fertilization increased the seed yield, but not the number of capsules, thousand kernel weight and the number of seeds per plant. N fertilization increased the seed yield especially in treatments with high sowing rates, in colder and wetter years. The number of seeds and capsules per plant as well as average stem yield were significantly influenced by the year and sowing rates. Oil concentration varied between the years, but the concentration of individual fatty acids was less variable. More than 50 % of oil concentration was formed by linolenic acid. Our results showed that linseed can be successfully grown in the sugarbeet growing region, especially when the summer is not too warm and dry.
