Abstract

The study was conducted to assess the effects of different vermicompost doses on the growth and yield of Brassica pekinenis L. The experiment was designed in a completely randomized block design with 4 replications under greenhouse conditions in Tra Vinh. The results showed that when the dose of vermicompost increased, the growth and yield parameters of the Brassica pekinenis plant increased. In particular, using vermicompost at 20 tons/ha, at the harvest (37 days after planting), the growth and yield parameters reached the highest with a plant height of 28.6 cm, a foliage diameter of 33.3 cm, an average plant weight of 177.26 g and a net yield of 29.13 tons/ha. In comparison with the treatment without vermicompost (NT1), when adding vermicompost with 2 tons/ha (NT2), 6 tons/ha (NT3), 10 tons/ha (NT4), 20 tons/ha (NT5) the yield of Brassica pekinenis increased by 49.27%, 85.67%, 101.01%, and 226.20% respectively. Consequently, this study showed a positive correlation between the vermicompost dosage and the growth and yield of Brassica pekinenis L.
