Abstract: Field experiment at Indonesian Vegetable Crops Research Institute, Lembang, West Java, Indonesia was conducted to examine the effect of plant spacing and the number of cloves per planting hole on purple blotch disease (Alternaria porri), growth, and yield of garlic.The garlic cultivar used was an Indonesian local cultivar, Lumbu hijau.The first experiment was arranged as split plot in a randomized complete block design with three replications.The main plots were plant spacing with six levels (10x5 cm, 10x10 cm, 10x15 cm, 10x20 cm, 15x20 cm, and 20x20 cm) and the sub plots were the numbers of garlic cloves per planting hole with four levels (1, 2, 3 or 4 cloves).The second experiment was conducted to examine the growth and yield of garlic planted with optimal combination of spacing and the number of seed clove (10x15 cm plant spacing with two cloves), compared to the common practice (10x15 cm plant spacing with one clove per hole).The results of the first experiment showed that plant spacing and the number of clove per planting hole examined did not significantly affect the development of purple disease in garlic.The garlic growth was influenced by the number of clove per hole rather than plant spacing.In both experiments, combination plant spacing of 10x15 cm with two cloves per planting hole increased the garlic yield per unit area 2.3-3.2folds compared to farmer's common practice.This study showed that appropriate combination between plant spacing and the numbers of cloves per planting holes can increase the garlic productivity.
