Conclusions
The results of our study demonstrate that DSR can produceyields comparable with that of PTR, provided that weeds areproperly controlled. The use of a combination of postemergenceherbicides for grass, sedge, and broadleaved weeds provided higheryield than the application of a single postemergence herbicide.Without any control measure, weed pressure was higher in DSRand WSR than in PTR. Grasses were higher while sedges andbroadleaved weeds were lower in DSR as compared to PTR andNPTR. In both seasons, herbicide efficacy was better in DSR andWSR than in the other establishment methods.
