Determination of Weed Species in Kiwifruit Orchards of Ordu Province-Turkey

This study was conducted to determine weed species, their frequencies (%), coverage areas (%) and their densities (plant/m²) in kiwifruit orchards of Ordu province in 2015. As a method Ordu was divided into four parts of the research area; Altınordu-Gülyalı, Ulubey-Kabadüz, Perşembe-Fatsa-Çamaş, İkizce-Ünye-Çaybaşı. The study was carried out in two different periods which are April-May and September-October in the year of 2015. Study was started from the center of Ordu and stopped for every 5 km to make four different examinations of randomly selected 1 m² area of 1 da the kiwifruit orchard. During examinations weed species, their frequencies (%), coverage area (%) and their densities (plant/m²) were determined. Eighyt six weed species belonging to 32 families were determined in the survey which was carried out in 26 kiwi orchards. At the end of this survey which is conducted in two different periods, general weed coverage is found out to be 82.27 % for the first period (April-May) and 80.12 % for the second period (September-October). Among these families the largest family was found to be Asteraceae having 18 species. In the first period (April-May) 71 species were identified belonging to 30 families and the most frequently encountered weed species was Convolvulus arvensis L. (field bindweed) by 69.23 %. In the second period (September-October) 67 species were identified belonging to 30 families and the most frequently encountered weed species was C. arvensis L. by 53.85 %.
