In agroecological conditions of South Serbia, the influence that row spacing has on sainfoin seeds yield and quality was examined. The Makedonka cultivar was sown at the row spacing of 20,40 and 60 cm. The three year average seed yield of 483.5 kg ha-1 was made. The first year yielded the lowest (256.1 kg ha-1), whereas the highest was in the third and last year of research (649.0 kg ha-1). With respect to the row spacing, the highest yields were achieved at 40 cm (514.3 kg ha-1), and the lowest at 20 cm (428.7 kg ha-1). The row spacing had a significant effect on the quality of the seed. The highest germination energy (86.7%), seed germination (90.4%), 1000 kernel weight (25.2 g), along with the lowest hard share of hard kernels (3.5 %) were obtained at 60 cm of row spacing.
