The experiment was conducted to determine the effects of the ratio of leaf removal from bottom of plants (0, 4, 8 and 12 leaves / plant) shortly before flowering on yield components and some quality characters of sunflower ecotypes (Amasya, Uşak, Ki{dotless}rşehir, Erzurum, Iǧdi{dotless}r-2, Çorum-2, Edirne-1, Çorum-1, Line-1 ve Iǧdi{dotless}r-1). Based on the results, seed setting, seed yield, kernel ratio, crude oil and crude protein content of seeds crude oil yield and crude protein yield changed with different degrees of leaf removal. Head diameter, seed setting, seed yield, 1000 seed weight, kernel ratio, crude oil, crude protein content, crude oil yield and crude protein yield varied with degree of leaf defoliation of some ecotypes while those characters were not affected by defoliation in some ecotypes.
