Abstract

This study was carried out on the Yuvarlak Çekirdeksiz grape variety grown in the Siirt University application vineyard. Three different times and four different doses [control (0 ppm), 1st application (1000 ppm before flowering), 2nd application (1000 ppm before flowering + 1000 ppm after flowering), 3rd application (1000 ppm before flowering + after flowering) 1000 ppm + veraison 1000 ppm)] applied liquid seaweed on phenological stages and its effects on Total Effective temperature (TET) were compared. When the phenological periods were compared with the control; It was determined that the first application took the full flowering phase three days earlier and the veraison phase six days earlier. The Total Effective Temperature value between full bloom and veraison was determined to be between 659.78-819.98 gd, and it was determined that the first application shortened the vegetation period compared to the control, while the other two applications extended the vegetation period.
