EFFECT OF VERMICOMPOST AND MINERAL FERTILIZER ON ECONOMIC PERFORMANCE OF GARLIC (Allium sativum L.), IN HARAMAYA, EASTERN ETHIOPIA
Abstract
Garlic (Allium sativum L.) is an important vegetable crop in Ethiopia. The yield of the crop is often constrained by
low and unbalanced nutrient supply in the soil. This study assessed the response of garlic variety (Chelenko I) to
vermicompost and mineral Nitrogen (N) fertilizer application on growth and bulb yield of the crop during the
2016/2017 rainy season in Haramaya University main campus, Ethiopia. The treatment consist of a factorial
combination of four levels of vermicompost (0, 2.5, 5 and 7.5 tha-1) and five levels of mineral N fertilizer (0, 52.5,
80, 105 and 130 kg N ha-1), were laid out in a randomized complete block design under a factorial arrangement
and replicated three times. Results revealed early maturity (130.48 days) at no fertilizer application, while late
maturity (135.50 days) was with application of 7.5tha-1 of vermicompost. Significant (P < 0.05) maximum clove
weight (2.71g/clove), and marketable bulb yield (12.32tha-1), were recorded at the rate of 7.5tha-1 of
vermicompost, followed by lower dose of mineral N fertilizer. Also, leaf number (13.33) was recorded at
combined application of maximum rate of vermicompost (7.5tha-1) and mineral N fertilizer (130kgha-1). Due to
combined application of vermicompost (7.5tha-1) and mineral N fertilizer (130kgha-1), unmarketable bulb yield
was reduced by 41.03% over the control. The highest net benefit was estimated due to the maximum marketable
bulb yield of garlic obtained along with application of 7.5tha-1 of vermicompost and 130kgha-1 of mineral N
fertilizer. Therefore, these rates could be considered in the production of garlic in the study area.
