Grape is considered as one of the world's most important crop. Climatic and soil parameters can significantly affect the yield and quality of grapes. The aim of this study was to analyse and assess this impact of soil and climatic conditions on table grape yield and quality. The experiments took place on a commercial table grape vineyard in Greece for three successive years (2015, 2016 and 2017). The climatic conditions were found to affect significantly the table grape yield and all the tested quality parameters apart from the berry density and titratable acidity. In addition, the climatic conditions affected the table grape yield and quality but in a different degree per phenological stage. The effect of soil conditions on table grape yield and quality parameters differed significantly per annum due to the climatic conditions variation in terms of temperature and precipitation. The conducted analysis highlighted that the information regarding the combined effect of weather and soil conditions on the spatiotemporal variability of the production of table grapes in terms of their quantity and quality is an essential component of the modern precision viticulture. Based on the contemporary principles of the precision viticulture, appropriate cultivation practices can be planned and implemented, reducing thus the impact of climate change on the vine production efficiency and quality.
