Eight Hungarian vetch varieties were used in the study. In Bingöl province, where the research was carried out, flowering of Hungarian vetch started on April 18. Counts started on April 23 and ended on May 11. Hungarian vetch remained blooming for about three weeks in Bingöl province. An average of 14.9 bees per m2 visited the Hungarian vetch and the bees remained on the flower for an average of 9.0 seconds. It has been determined that Hungarian vetch has an average of 377 flowers per m2, the natural plant height is 38.7 cm, the fruit per plant is 21.3, the seed per fruit is 4.0, the seed yield is 22.5 kg/da, and the thousand-seed weight is 33.0 g. Also, it was observed that the Hungarian vetch reached the highest natural plant height by April 30, the number of bees visiting the plant was high on May 04-07, the bees stayed on flower for a long time when the plant bloomed the most. It was seen that Kansur and Efes varieties are distinguishable for the features such as the number of bees per m2, the duration of the bee staying on flower, and the number of flowers, while the features such as natural plant height, seed yield and thousand-seed weight, are distinguished in Akçalar, Efes and Tarm Beyazı varieties.
