The study was carried out to determine the effect of clove size and planting depth on yield and yield components of garlic (Allium sativum L.) in Bale zone Madawalabu University experimental site during the 2016 autumn cropping season. The treatments consisted of three cloves weight viz., large (3.60-4.5 g), medium (2.6-3.5 g) & small (1.5-2.5 g) and four planting depth (i.e. 1.5, 2.5, 5 and 7cm) using Kuriftu variety. The experiment was conducted using a randomized complete block design (RCBD) in a factorial arrangement with three replications each. The results of study revealed that interaction effects of clove weight and planting depth significantly influence the plant height, mean bulb weight, total bulb yield and bulb diameter. The highest plant height, mean bulb weight, total bulb yield and bulb length were obtained when medium cloves weight and 2.5-5 cm planting depth, whereas the lowest plant height, mean bulb weight, total bulb weight and bulb diameter were obtained when small cloves weight and 1.5 cm and 7cm planting depth was used. The main effects of clove size had significant influence on days of emergency, leaf length, leaf number per plant, total bulb weight, un-marketable yield and marketable yield. For all parameters the highest and lowest result was observed for plants that were raised from medium weight cloves and small clove weight respectively and highest result was observed in 5cm and lowest in 7cm depth of planting, respectively. The results of this study indicated that, using medium clove weight (2.6- 3.5g) with 2.5-5cm planting depth produced higher vegetative growth parameters, maximum garlic bulb yield and bulb quality (bulb diameter and average bulb weight). Therefore, it is suggested that planting medium clove weights with planting depth of 2.5-5cm produces higher bulb yield and enhances the quality of garlic.
