Summary: Early garlic (Allium sativum L.) cultivars are an alternative for growing this vegetable in low-altitude semi-arid regions, due to its lower requirement for mild temperatures and photoperiod. However, it is necessary to identify the cultivars that best adapt to these environmental conditions to improve management and maximize their production characteristics. In this sense, the objective was to evaluate early garlic cultivars’ biometric, yield, and quality characteristics under low altitude conditions in the semi-arid region. Two field trials were carried out in a Brazilian semi-arid region to evaluate 14 early-cycle and virus-free garlic cultivars. The climatic variations between the experiments influenced the performance of some cultivars in terms of biometric, yield, and quality characteristics. ‘Inhumas Casca Roxa’ (65.25 and 57.62 cm; 6.49 and 6.48 t in 2022 and 2023, respectively) and ‘Ugarte’ (61.70 and 55.14 cm; 6.34 and 5.62 t in 2022 and 2023, respectively) showed higher height and total yield. Likewise, ‘Inhumas Casca Roxa’ and ‘Ugarte’ stood out for bulb mass (20.00 and 19.61 g respectively), and percentage of bulbs in classes 5 (30.6% and 32.8%, respectively) and 6 (8.3% and 9.2%). These materials also showed good post-harvest quality characteristics, such as high pungency for fresh consumption and/or processing by industry. It is recommended to cultivate ‘Inhumas Casca Roxa’ and ‘Ugarte’ for garlic production in low-altitude semi-arid conditions.
