The materials used were green fortune pakcoy seeds, liquid complementary fertilizer, compost, husk charcoal, and NPK fertilizer while the tools used were polybags and bamboo racks. The research variables observed were the number of leaves, leaf width, plant height, plant fresh weight, and plant dry weight. The results showed significant differences in plant height, leaf width, and several leaves seen after the plants were 21 DAP.
