Abstract :

Strawberry (Fragaria × ananassa) belongs to the Rosaceae family. One of the most critical challenges of strawberry production is the plants that cause problems in harvesting and reduced yield. This study was carried out to identify weed flora in strawberry growing regions in Kurdistan province. In this study, determining the genus and species of common weeds in the strawberry fields of two regions was investigated. For this purpose, 13 farms in 6 villages in the Kamyaran region and 11 farms at 11 villages in the Marivan region with the more cultivated area than their surrounding villages were selected. The results of weed flora study in Sanandaj-Kamyaran axis farms showed that the most prevalent weeds in Sanandaj-Kamyaran axis strawberry fields are related to broadleaf weeds including (Convolvulus arvensis L.), (Cirsium arvense), (Acroptilon repens), (Setaria viridis L.), (Allium canadense L.) and (Vicia persica Boiss) with dominance index of 201.5, 200, 193.72, 193.48, 192.24 and 190.64 respectively. The first three weeds were perennial weeds, and the last one was an annual weed. However, among the narrow-leaves annual weeds, (Setaria viridis) had the highest prevalence index (193.48) due to traditional irrigation using rivers and streams, which carry weed seeds in their path. However, in the Marivan region, all species had a high prevalence index, although Portulaca oleracea L. and Cynodon dactylon L. had a higher dominance index than the others.
