Growth and Bulb Yield of Garlic as Influenced by Clove Size

Abstract

Garlic is an important cash crop in many regions of Ethiopia. However, the yield of the crop is constrained by several factors. Among these, inappropriate clove size is one of the major agronomic practices that can decrease the yield of the crop. Hence, a field experiment was conducted during the 2020/21 main cropping season at Debre Berhan University, College of Agriculture and Natural Resource Sciences, demonstration and research site to evaluate the effect of clove size on growth and bulb yield of garlic (Allium sativum L.). The treatments consisted of five clove sizes: 1–1.49 g, 1.5–1.99 g, 2–2.50 g, 2.51–2.99 g, and 3–3.5 g. An improved variety “Tseday” was used as a planting material. The experiment was laid out as a randomized complete block design in a factorial arrangement and replicated for three times. The results revealed that clove size significantly influenced all growth and yield parameters of garlic. Planting of 3–3.5 g cloves reduced days to emergence by 11 and 6.33 days and days to maturity by 28.33 and 18.00 days, respectively, as compared to planting of 1–1.49 g and 2–2.5 g cloves. This treatment also increased total bulb yield by 25.88% and 15.58%, respectively, as compared to planting of 1–1.49 g and 2–2.5 g cloves. In addition, this treatment significantly increased most of the growth and bulb yield components. Hence, it can be concluded that planting of 3–3.5 g cloves could be recommended to enhance early emergence, good vegetative growth, and total bulb yield of garlic.

The Sensitivity of Four Garlic Genotypes on Low Temperatures and the Role on Dormancy Breaking

“…The VID value had a positive and significant correlation with clove diameter, which means the larger the clove diameter, the higher the VID value. Desta et al (2021) explained that large bulbs germinate faster due to the more excellent supply of carbohydrates in the cloves. The pattern was suited to Chinese softneck garlic.…”

Duration of of Low-Temperature Storage, Clove Topping and Gibberellic Acid on Emergence, Yield and Yield Components of Garlic

“…Garlic ( Allium sativum L.) belongs to Alliaceae family, and it is believed to be originated in Central Asia (India, Afghanistan, West China, and Russia) and spread to other parts of the world through trade and colonization and used worldwide as a spice, functional food, and medicinal plant [ 1 ]. Garlic bulbs have a dormancy period of more than three months.…”

Adaptive Garlic Farming on Climate Change and Variability in Lombok

“…On the other hand, excessive amounts of water will accelerate rotting process (Oliveira et al, 2020). Desta et al (2021) reported that rainfall amount also influenced the total harvested area or the yield of garlic. The requirements for optimal garlic cultivation are temperatures in range of 20-25°C and annual rainfall of 1,200-2,400 mm (Atif et al, 2020).…”
