Aims: This study was planned to determine the effects of organic and organomineral liquid fertilizers on yield, quality and plant nutrition on Black Magic grape variety grafted on 1103 P grape rootstock. Methods and Results: In the study, foliar and soil, organic (BioGas, 400 cc 100 L-1 and 4 L da-1, respectively) and organomineral (AminoSEL-K, 300 cc 100 L-1 and 4 L da-1, respectively) fertilizer applications were made separately and together. As a result of the research, the effect of fertilizer applications on yield and cluster weight, and plant nutrition was not significant, and the effect on must characteristics was found to be significant. The highest Total Soluble Solids value was obtained from organomineral (17.63 %) and organic+organomineral (17.48 %) applications. In the study, it was determined that the method of application was important. The highest yield and cluster weight (8145 g and 407.3 g, respectively) were obtained from foliar applications. Conclusions: As a result, it was concluded that it would be appropriate to continue the study in the following years in order to make definite suggestions about fertilizers and application method. Significance and Impact of the Study: It was concluded that the effects of the liquid organic and organomineral fertilizers used in the study on the grape yield and quality can be seen starting from the first year and the effect will continue to increase in the following years.
