Optimizing Eco-enzyme Dosage on Kale (Brassica oleracea) Growth and Production
Abstract
Kale, a member of the cabbage family, is currently witnessing an increase in popularity; however, this heightened interest is not reflected in production levels, primarily due to the excessive application of inorganic fertilizers. To mitigate this challenge, implementing organic fertilizers, such as eco-enzymes, may enhance kale yield. A research study was carried out at the experimental field of the Faculty of Agriculture at Muhammadiyah University of Jakarta from June to October 2022. The study employed a Randomized Block Design (RAK) with six varying doses of eco enzymes, ranging from a control group to 50 mL per plant. Each treatment was replicated four times, with three plants allocated to each experimental unit. The parameters assessed included the number of leaves, leaf length, leaf width, gross weight, consumption weight, and root length. Data analysis, utilizing variance (F test) and the DMRT test at a 5% significance level, indicated that varying doses of eco enzymes had a significant impact on plant height, leaf length, gross weight, and consumption weight while showing no significant effect on the number of leaves, leaf width, and root length of the kale plants.
