KOMPOSISI PUPUK ORGANIK DENGAN TANAH TERHADAP PERTUMBUHAN SAWI (Brassica rapa)

The growth of mustard greens (Brassica rapa) requires nutrients for the plant's needs, one of which is using compost from the Centrosema pubescens plant and organic fertilizer from livestock manure. The Centrosema pubescens plant can be used for plant compost. The Centrosema pubescens plant was chosen because it is easy to find and easy to grow in various soil conditions. This research was carried out at the experimental garden of the Muhammadiyah University of Malang, Malang Regency, East Java. The research was carried out in May – July 2024. This research used a simple Randomized Block Design. There were 12 treatments, in each treatment there were 4 plant samples and each treatment was repeated 3 times, the total plant samples used were 144 plants. Sow Pakcoy mustard seeds in soil media for 2 weeks and transplant them into polybag media containing several compositions used, namely a mixture of organic fertilizers. The treatment of compost and manure had a significant effect on the parameters of plant height, number of leaves, stem diameter, plant leaf area, weight of the top of the plant, weight of the bottom of the plant, and total weight of the plant.
