| Abstract: |
| Indiscriminate distribution of vegetable waste can increase the risk of nonpoint agricultural pollution. In this study, a comparison was made among four composts formed from vegetable waste and two commercial fertilizers used to promote the growth of Brassica chinensis. All six agents were matched at a nitrogen contents of 37.5 kg·hm-2. The height, leaf area, and nutrient contents of N, P, K, Ca, and Mg of Brassica chinensis were measured. We found that a vermicompost formed from vegetable waste and 10% wheat straw was the most effective treatment for Brassica chinensis growth. Cabbage height and leaf area with this treatment were 3.10~4.00 and 3.20~3.53 times as large, respectively, as those grown with commercial organic fertilizer. Cabbage height and leaf area were also 25%~35% and 16%~42% larger, respectively, than those for cabbages grown in the presence of the other vegetable waste composts. The N and P contents of the cabbage increased when a vermicompost was used in comparison to the other composts but the difference was not statistically significant. However, the K, Ca, and Mg contents of the cabbage increased significantly. These results highlight the advantages of using vermicompost for the production of green vegetables. They also provide a scientific reason for encouraging the responsible use of vegetable waste in agriculture. |
