Garlic has a worldwide economic importance; this vegetable can be consumed fresh or processed by food industries. However, few studies evaluate its postharvest quality. It is necessary to establish cultural practices and methods that focus not only on increase of yield, but on obtaining a product with better postharvest quality. The objective of this work was to evaluate the bulb quality of conventional garlic and virus-free garlic as a function of seed clove size and space between plants. Two experiments were conducted simultaneously in Portalegre, Rio Grande do Norte, Brazil. A randomized block experimental design with four replications was used in both experiments. The treatments were arranged in split-plots, with the seed clove size (large and small) in the plots, and the plant spacings (7.5, 10.0, 12.5, and 15.0 cm between plants) in the subplots. The use of large seed cloves resulted in higher bulb diameter and titratable acidity (TA). Soluble solids (SS), total soluble sugars, SS to TA ratio, and total solids decreased as the space between plants was increased, regardless of the seed health and seed clove size. Virus-free garlic seed cloves planted with spacing of 12.5 and 15.0 cm resulted in higher bulb diameter, TA, pungency, and industrial index, i.e., they produced better quality bulbs with good prospects for industrialization.
