Abstract
Mustard greens (Brassica Juncea L.) are one of the leafy vegetables that are not difficult to cultivate. Brassica Juncea L. is classified as a leafy vegetable plant that has high economic value and is very popular with the community. Mustard greens grow well in soil with high nitrogen content. In addition to the N element, the P element, and the K element also play an important role in plant growth. NPK 16:16:16 fertilizer is a compound fertilizer needed by plants. The method used is the experimental method, namely placing plants in a laboratory exposed to sunlight, and observing their development. Mustard green seeds are inserted into the planting medium in the form of fertile soil, which is placed in a shady place. Plants are watered using water every 7 days. The observation parameters observed are the percentage of germination and plant height. Plants planted in planting media with NPK addition treatment grow faster and better, compared to plants planted in planting media without NPK addition.
