The effectiveness of liquid organic fertilizer (LOF) can be improved by incorporating micronutrient zinc (Zn) in its production process in order to increase the yields of organic vegetables such as sweet corn. This experiment was conducted to determine the effect of Zn amendment on LOF nutrient quality, nutrient uptakes, and sweet corn yields. Results indicated that Zn-enriched treatment during the production of LOF did not significantly affect N, P, and K contents, but significantly affected pH. There were also no significant effects on P and Zn contents in the leaves of sweet corn as well as those uptakes by the plants. However, the P contents in the leaves at a day before harvesting were significantly higher than 5 weeks after planting, while the Zn content showed a contrasting result. Moreover, the use of Zn-enriched LOF did not significantly affect the weights of husked and unhusked ears of sweet corn, but significantly decreased its sweetness. Future research should focus on the use of lower concentrations of Zn.
