This study was carried out Razakı (Vitis vinifera L.) grape cultivar and its vine, which was grown on their own roots in a vegetation period of 2015 in Tuzlukçu district in Konya province. In this research, it was examined the effects on Control (C), 25 bud/vitis (crop load), 30 bud/vitis, 35 bud/vitis, 25 bud/vitis+TKI–Humas (soil), 30 bud/vitis+TKI–Humas (soil), 35 bud/vitis+TKI–Humas (soil) applications on grape yield and quality of Razakı grape cultivar. The results were obtained as the highest cluster weight (90.53 g) with 30 bud/vitis+TKI–Humas (soil), (88.75 g) with 25 bud/vitis, (88.04 g) with C, (83.46 g) with 35 bud/vitis+TKI–Humas (soil) and (83.40 g) with 35 bud/vitis applications; the longest cluster (20.91 cm) with C application; the highest berry weight (3.48 g) with C application; the longest berry (19.98 mm) with C application; the highest oBriks (21.50%) with C and (21.40%) with 25 bud/vitis applications; the highest TA (1.09 g TAE/100ml) with 35 bud/vitis, (1.09 g TAE/100ml) with 25 bud/vitis+TKI–Humas (soil), (1.09 g TAE/100ml) with 30 bud/vitis+TKI–Humas (soil) and (1.08 g TAE/100ml) with 30 bud/vitis applications; the highest maturity index (25.41) with C application; the highest must yield (726.67 ml) with 25 bud/vitis, (700.00 ml) with 35 bud/vitis and (695.00 ml) with 30 bud/vitis applications; the highest intensity of a* color (-5.79) with 30 bud/vitis+TKI–Humas (soil) and (-5.76) with 25 bud/vitis+TKI–Humas (soil) applications. No significant effects were found on grape yield, cluster width, berry width, berry lengt/berry width, pH, L* and b* color intensity values.
