Optimizing Bitter Mustard Plants (Brassica Juncea L.) Growth and Production by Administering Inorganic Fertilizer and Liquid Organic Fertilizer
Abstract
Bitter mustard greens (Brassica juncea) are a leaf vegetable widely consumed in Indonesia. This research aims to evaluate the effect of a combination of NPK fertilizer and liquid organic fertilizer from banana weevils on the growth of bitter mustard greens. The method used was a factorial randomized block design with two factors (NPK and organic fertilizer) and three replications. Analysis of variance was carried out to analyze significant differences between treatments, with further tests using Duncan's Multiple Range Test (DMRT) at a significance level of 5%. The results showed that treating 10g NPK + 100ml POC Banana Stem and 10g NPK + 200ml POC Banana Stem consistently gave the best results on various growth parameters of bitter mustard plants. The 10g NPK + 100ml POC Banana Stem treatment produced the highest plant height at each observation stage, while the 10g NPK + 200ml POC Banana Stem treatment showed the highest number of leaves and plant fresh weight. The combination of NPK fertilizer and banana hump liquid organic fertilizer has proven to be effective in improving the growth quality of bitter mustard greens, including plant height, greater number of leaves and optimal fresh weightDownloads
