The climate in the region, particularly during the winter and spring, was characterized by significant rainfall, which contributed to the swift vegetative growth of grape varieties from bud burst to bloom. The primary objective of this study was to ascertain the most effective soil tillage technique. This involved evaluating the impact of various soil tillage methods (conventional, minimized, conservation) and shoot lengths (1.0 m and 1.5 m) on the vegetative growth and water stress levels in Cabernet Sauvignon, with an emphasis on controlling vegetative growth. The findings indicated that conservation tillage resulted in the most favorable outcomes, with the lowest pruning weight (1.58 kg.vine-1), leaf area (142.38 cm²), and yield (3.2 kg.vine-1). When considering different shoot lengths, the shortest shoot length (1.0 m) led to a minimal pruning weight of 1.69 kg per vine. The study concludes that, under the conditions in Tekirdag, conservation soil tillage, alongside conventional methods, is advisable for Cabernet Sauvignon cultivation due to its beneficial impact on leaf water potentials.
