“68”7. SUMMARY This study, which was carried out in Sivas, in 1983 and in 1993, has he®n conducted ta determine the weed seed mixing with wheat depending on the harvesting types and to determine some morfological features of them seeds. The weed seeds mixed with the wheat samples of 500 - 1.000 gr of obtained from se lector centres, was seperated and the fallowing results were obtained. 1. In 1983, 49 weed species mixed with wheat were iden tified. These species consisted of 3 monocot i ledon and 46 di- coti ledon species» 47 species found in scythe-machine stack harvest and 38 of them were in combine harvested samples. 2 species found in combine harvested were not noticed in the other type of harvest. 2» In 1993, 32 weed species mixed with wheat. belonged 3 monocot i ledon species of weed and 29 dicotiledon species of weed were determined. 27 species of weed seed were found in scythe-machine stack harvest and 28 species of weed seed were determined in combine harvested saples. 5 species found in combine harvested samples weren not noticed in scythe-machine stack harvest while 4 species found in scythe-machine stack harvested samples were not noticed in combine harvested yield» 3. 51 species of weed have been found from the samples of wheat obtained in 3 983 and in 1993.
