In this study, were determined the effects of row spacing on some agricultural properties of the guar (Cyamopsis tetragonobla). The experiment trials for this study were conducted in the Canakkale Onsekiz Mart University at Dardanos Research and Experimental Trials Unit of the Faculty of Agriculture in 2015. The experiment using Randomized Complete Block Design with 3 replications was applied two Guar. Five row spacing (20, 40, 60, 80 and 100 cm) according to the results. Row spacing had no effect to plant height and dry matter contents as it significantly affected alter properties. The highest green (2323.70 kg da(-1)) and dry (714.1 kg da(-1)) hay yield were obtained from 20 cm row spacing. Maximum number of branches (8.73 number) and flowers (72.40 number) were obtained from the row spacing of 100 cm while the number of leaves (247.23 number) and of stem diameter (11.59 mm) were achieved using 80 cm of row spacing. The number of branches, number of leaves and stem diameter increased with wider row spacing due to the availability at were space per plant to grow, but green and dry hay yields were decreased. In conclusion, 20-40 cm at row spacing may be suggested in guar for hay production.
