Abstract :

This, study was carried out during 2009-2011 in Manisa. The aim of this study was to found out species, their density and frequency of weeds in the conventional and organic vineyards. Weeds problem was surveyed in 76 conventional and 48 organic grape vineyard production fields. In the conventionally grown vineyards, 10 weed species were identified in summer period and nine weed species during the winter. According to the results of survey, they indicated that Stellaria media (L.) Vill. (47.4%) was the highest frequency in conventional vineyards during the winter in inter-row. The frequency of occurrence of other weed species ranged from 8.2% to 42.3%. In intra-row of conventional vineyards during the winter period, Hordeum murinum L. (42.8%) was found in the highest frequency. In other hand, Cynadon dactylon (L.) Pers. (51.3% to 64.8%) was found the highest frequency in inter row and intra row. In organic vineyards, 24 weeds species were identified in winter period. Stellaria media (L.) Vill. (56.0%) was the highest frequency. Matricaria chamomilla L. (54.3%) had the highest frequency in intra-row. In 13 species determined in organic vineyard in the summer, Cynadon dactylon (L.) Pers. (64.8% to 70.1%) was the highest frequency in intra-row and inter row.
