The popular trend for consuming vegetables that are safe for health has increased leading to the introduction of organic fertilizers in vegetable production, especially vermicompost. The aim of this experiment was to assess the response of vermicompost application of Eudrilus eugeniae at four levels: 1000, 2000, 3000 and 4000 kg per rai compared with control (without vermicompost application) and 12-8-8 chemical fertilizer at rate of 75 kg per rai for baby pak choi production. Vermicomposts were applied three times, the first was mixed with planting material. The other two times were applied to baby pak choi at 10 and 20 days after transplanting, whereas chemical fertilizer was applied two times,- a basal application and another 10 days after transplanting. The experiment was arranged in a Completely Randomized Design, with four replicates, ten plants per replication. The experiment was conducted during January to March, 2018 at experimental field of the Agricultural Technology Department, Faculty of Technology, Mahasarakham University. The results showed that baby pak choi grown in mixtures of planting material with 3000 kg per rai vermicompost had the maximal characteristics of plant height, stem diameter, leaf number and fresh weight per plant, close to a level similar to those grown in mixtures of soil with 12-8-8 chemical fertilizer at 75 kg per rai (P < 0.01).
