DOI : 10.21566/tarbitderg.281305 - This research carried out to determine some forage yields and qualities of common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica Crantz.) and hairy vetch (Vicia villosa L.) at three sowing times (5 october, 20 october and 5 november) and three harvest times (10 may, 20 may and 30 may) under Isparta conditions in 2011-2012 vegetation period. In this study; the highest hay yields were obtained at first sowing time and last harvest time at hairy vetch and Hungarian vetch (589.00 and 568.00 kg/da, respectively). While the highest crude protein yield was obtained at first sowing time in vetch species, it were determined that the highest crude protein yield at third harvest time in common vetch and Hungarian vetch (60.08 and 91.37 kg/da, respectively). There weren`t effect of harvest time on hairy vetch crude protein yield. While the least ADF and NDF mean content was determined at first harvest time (27.80% and 32.83, respectively), there weren`t effect of sowing time on ADF and NDF contents. In conclusion, Hungarian vetch and hairy vetch can be preferred to common vetch. Vetch species also can be early sown after summer main crop harvest and harvested at 20 may or 30 may for prevented to summer main crop sown.
