Abstract: Acroptilon  repens is an herbaceous perennial that propagates by seeds and vegetative means. Its natural range extends from Turkey throughout Central Asia to China. A. repens is a major weed for grape, orchards and meadow area in Central of Turkey. Our objective was to determine density and expanding of A. repens patches in Central of Turkey. The patche experiments were conducted for an 6 undisturbed meadow in 2002-2003. Six of 1x1=1 m² plots were randomly selected in each patch (2 central (C), 2 middle (M) and 2 edge (E). Shoot density and height of A. repens were recorded at two different times (May and August) and also, fresh-dry weight and patch growth were recorded in August for each of the years from each plots The results of the 6 patches experiments for shoot height of A. repens in 2002 and 2003 ranged from 24.94 -31.33 cm and 19.31-25.41 cm plot ^-1, respectively. In addition to this, the shoot density of A. repens in 2002 and 2003 ranged from 5.83-26.83 shoot plot^-1 and 7.50-24.83 shoot plot^-1, respectively. The shoot density of A. repens was higher in central plot than the edge plot in 2002-2003. The patches of A. repens in Goreme1,  Urgup 1, Urgup 3 and Urgup 4 in 2002-2003 were extended totaly 5, 16, 9 and 12 shoot plot^-1, respectively.
