Performance Trial of Vermicompost on the Growth and Yield of Garlic (Ilocos White Shank)

Abstract

The garlic (Allium sativum) variety "Ilocos white shank" was subjected to two levels of vermicompost application to determine its plant height, bulb diameter, and its yield. Complete Randomized Design (CRD) was used to test the performance of the garlic under two levels of vermicompost application, namely; T1 -Control (No vermicompost applied); T2 -Vermicompost @ 2 tons/ha; T3 -Vermicompost @ 4 tons/ha.Results of the study revealed that the height of garlic plants fertilized with vermicompost at the rate of 20 grams/hill (4 tons/ha) produced the tallest plants with a mean of 62.8 cm, followed by 47.3 cm (2 tons/ha of vermicompost) and the least was observed in the unfertilized plots with a mean of 44.13 cm. The diameter of the garlic bulb produced in the study was greatest at 3.85 cm when fertilized with vermicompost at the rate of 4 tons/ha, followed by 3.37 cm in plants applied at the rate of 2 tons/ha. The yield of garlic, Ilocos white shank is highly favored by the application of vermicompost at the rate of 4 tons per hectare, which gave a mean yield of 3.840 tons/ha, followed by the application rate of 2 tons/ha, which gave a yield of 2.867 tons/ha while the unfertilized plot recorded a yield of 2.707 tons/ha.
