Özet:

: The present study was conducted to determine the effects of soil tillage system to be used in safflower farming in Sivas, Turkey in terms of plant emergence and yields characteristics. Soil tillage systems were arranged as; conventional soil tillage (STS-1) with moldboard plough, conservation soil tillage system-1 with gobble disk (STS-2) and conservation soil tillage-2 with chisel plough (STS-3). Linas and Remzibey-05 safflower cultivars were used in experiments. In Linas and Remzibey-05 cultivars, the greatest and the lowest mean emergence dates were respectively observed in STS-3 and STS-2; the greatest and the lowest percentage of emerged seedlings were respectively observed in STS-2 and STS-1. In Linas and Remzibey-05 cultivars, the greatest mean germination dates was observed in STS-3 with chisel and the greatest emerged rate index and percentage of emerged seedlings were observed in STS-2 with gobble disk. Plant yield parameters were greater in conventional soil tillage system. Except for first branched height and number of secondary branches per plant,, conventional tillage was followed by the system with chisel and the system with gobble disk had the lowest values. Seed yields varied between 72.82-88.55 kg da-1 in Linas and between 70.21-84.50 kg da-1 in Remzibey-05 cultivar.
