An experiment was conducted in Tuy Hoa city, Phu Yen province on the two garlic varieties (Ninh Thuan white garlic and Ly Son white garlic) with four different growing densities (666,667 plant per hectare-1, 833,333 plant per hectare -1, 1,000,000 plant per hectare -1 and 1,111,111 plant per hectare -1) to examine the plant growths and the yields of these garlic varieties in the experimental conditions. At the growing distance of 15 * 8 cm (833,333 plant per hectare -1), the plant’s height was (42.6 cm) and the last leaf number was (9.88 leaf per plant-1), which were not significantly different in comparison with the garlics grown at the density 666,6667 plant per hectare-1. The optimum bulb yield of Ly Son and Ninh Thuan white garlics which were cultivated in 833,333 plant per hectare-1 treatment was 7.67 tons per hectare-1 and 8.20 tons per hectare-1, respectively. The average bulb yield cultivated in this density 833,333 plant per hectare-1 was 7.93 tons per hectare-1, which was the highest bulb yield in comparison with the other treatments. Keywords: sandy soil, white garlic, plant density.Thí nghiệm hai giống tỏi trắng Ninh Thuận và Lý Sơn, với bốn mật độ trồng là: 666.667cây/ha, 833.333 cây, 1.000.000 cây và 1.111.111 cây/ha tại tp.
