DETERMINATION OF WEEDS IN RICE FIELDS OF SOUTH EASTERN ANATOLIA REGION OF TURKEY

This study was conducted in 2012 to determine the most prevalent and challenging weeds in the rice fields of Southeastern Anatolia, Turkey. Rice production in the region differs from the other regions as conservational tillage practices are being opted in the region in contrast to conventional tillage practices in the other regions of the country. As a result of the survey total 70 different weedy species belonging to 22 families were observed. The incidence and frequency of all the weedy species observed was calculated and families were ranked according to incidence and frequency. Poaceae, Asteraceae and Cyperaceae were the most prevalent families having 12, 12 and 8 species while the rest 19 families were represented with 1-4 species. This survey gives the current prevalence of weedy species in the rice fields, and the information being presented in this article will help in devising management options for the troublesome weeds in the region.
