Abstract

This study was carried out to determine the effect of plant spacing on growth and yield of local garlic (Allium sativum sativum) variety named Sangga Sembalun from Sembalun Higland of West Lombok District, Indonesia, from June 2018 to March 2019. The on-farm experiment was conducted in randomized complete block design (RCBD) for three plant spacing treatment which was 12 cm x 12 cm (T1), 12 cm x 10 cm (T2), and 10 cm x 10 cm (T3) with nine replication in 10 m2 plot size for each. The results showed that there was no significant difference on effect of spacing on plant height, number of leaves, fresh weight, dry weight, moisture content, bulb weight, bulb size (length and diameter), cloves number, and cloves weight. However, plot yield was higher at T3 (4.84 kg/m2) than T2 (3.71 kg/m2) and T1 (3.77 kg/m2) due to significant increase in population which was, in average, 153, 107, and 90 plant per m2 for T3, T2, and T1 respectively. Moreover, weight lost from fresh to dry yield was lower in T3 (55.32%) than T1 (58.13%). Weight lost in T3 was consistently the lowest at 4.35% after six months storage to produce seed bulb.
