Effect of different distance from hive on honey bee visiting, yield, yield components and lucerne seed quality components was investigated on group of 20 bee colonies. Presence of others pollinators beside honey bees were recorded. The highest number of honey bees on 1 square meter of area of flowering lucerne was on distance 50 m to 100 m. Distribution of these pollinators were similar on whole lucerne plot. The highest percent of pollinated inflorescences was recorded on 50 m distance (72.24%). The best pod setting (55.55%) was also on this distance. The highest number of seeds per pod was achieved on 100 m distance. On this distance produced seeds were smallest. The highest yield, 42.7 g/square meter was on 100 m distance from hive, on 50 m distance was 41.2 g/square meter, on 150 m - 38.9 g/square meter and the lowest yield was on 200 m distance from hive (38.1 g/square meter). Difference between yield on 100 m and 200 m distance was 4.58 g/square meter (10.73%).
