The investigation of yield and yield components of some sunflower (Helianthus annuus L.) cultivars in edirne ecological condition

This research was conducted in 2018 sunflower growing period in order to determine the yield and yield components of different sunflower varieties in Edirne ecological conditions. In this study; 24 different sunflower cultivars tested randomized block desigon with three replications. Plant height, stem diameter, head diameter, shelling ratio, thousand grain weight, hectoliter weight, crude oil ratio, crude oil yield, protein ratio and seed yield were exalvuted for cultures. According to the study results, it there is significant differences abtarha onone the varieties in terms of P <0.01 level. In the study, the rate of crude oil ranged between 39.73-50.66%, the highest grain yield was abtarha in Sanbro mr (552.52 kg / da) and SY Granit (500.2 kg / da) cultivars.
