Birdsfoot trefoil grown for seed (cv. Bokor) was examined in agroecological conditions of Western Serbia during period 2007-2009. The goal was to determine herbage yield which could be achieved growing seed crop, using different interrow spacing (12.5, 25 and 50 cm) and various seeding rates (2, 4 and 8 kg/ha). The highest hay yield was obtained in the third production year at the narrowest spacing and using the highest seeding rate (5.26 t/ha). Total hay production during 3 years using birdsfoot trefoil seed crop for herbage yield ranged from 9.11 to 14.83 t/ha depending on row spacing and from 10.74 to 13.2 t/ha depending on seeding rate. The highest stand density (8 kg/ha seeding rate and 12.5 cm interrow spacing) produced the highest herbage yield of birdsfoot trefoil in the combined usage (for forage and seed production).
