But on the other hand, weeds can be used as organic fertilizer because several types of weeds meet the requirements for plants that can be used as fertilizer. Organic fertilizer can come from harvest residues, plants that are specifically used as fertilizer or from wild plants. This research aims to analyze the effect of applying green fertilizer and to determine which green fertilizer combination of Tridax procumbens, Asystasia gangetica and Ruellia tuberosa weeds is effective on the growth of pakcoy plants. This research was carried out from August to December 2024. Data collection was carried out at the UIN Sunan Kalijaga Greenhouse and nutrient analysis at the UMY Agrotechnology Lab. There are 4 fertilizer combinations, namely TR (Tridax procumbens + Ruellia tuberosa), RA (Ruellia tuberosa + Asystasia gangetica), TA (Tridax procumbens + Asystasia gangetica), and TRA (Tridax procumbens + Ruellia tuberosa + Asystasia gangetica). Green manure is made using the wet chopping method with a ratio of 2:1 (2 kg of soil and 1 kg of weed leaves. Growth observations include plant height, leaf width, number of leaves, leaf length, root length. Chlorophyll analysis and nutrient analysis are carried out. Environmental parameters including temperature, light intensity, soil moisture and pH. The results showed that the combination of T. procumbens and R. tuberosa (TR) green fertilizer was the most effective in increasing leaf width, leaf length, number of leaves, root length of pakcoy plants with sequential values. 9.02 cm, 12.35 cm, 13.23 cm, and 12.25 cm. Based on the results, it can be concluded that the application of green fertilizer affects the growth of plant height, leaf width, leaf length, number of leaves, root length, and chlorophyll levels of pakcoy plants.
