This research was conducted in Bsiereen village of Hama province. The objective of this research was to identify the optimal plant density for the two varieties of garlic, namely Kiswany and Kurdy. A split plot design was used in this experiment. Kiswany and Kurdy were considered as the main factor while the treatments of the experiment were considered as a split factor [( 5 treatments for plant density: plating on lines: with four treatments (10 × 20, 15 × 20, 10 × 25, and 15 × 25), planting on both lines sides with a distance of (10× 45 cm)]. The total replicates for each treatment was three with an average of 10 plants for each replicate. The Gen Stat 32 was used for the analysis of data and the LSD was calculated at p≤ 0.05. The result of analysis shows the followings: - Kiswany plants superseded Kurdy plants almost for all growth indicators and this was reflected positively in its productivity. - Treatment number 5 (planting on both sides of the line: 10 × 45 cm) has proven to show the best results for almost all the studied characteristics and indicators. -The interaction of a variety with treatment 5 affected positively most of the characteristics of the total green parts of the plants for both varieties of the treatment. This was reflected as an increases in their productivity. - An increases in a plant density for treatment one for Kiswany (planting on lines: 10 × 20 cm) has increased the productivity but this was not the case for Kurdy variety.
