Pertumbuhan dan Produksi Tanaman Edamame (Glycine max (L.) Merrill) terhadap Pemberian Kompos Kulit Kopi dan Mulsa Jerami Padi

Abstract

Edamame is a vegetable soybean that originated in Japan, and can be consumed as a vegetable or snack. Edamame has opportunities as an export commodity that can increase the country's foreign exchange, but Edamame production in Indonesia is still very low. In increasing Edamame production, one thing that greatly affects it is the availability of nutrients, namely by applying coffee husk compost and rice straw mulch. This research was carried out on Jalan Harmonika baru, Padang Bulan Selayang II, Medan Selayang District, Medan, with a place altitude of ±25 meters above sea level, starting from May-August 2024. This study uses a Factorial group random design (RAK) consisting of 2 factors with 3 replicates. The first factor is the dose of coffee husk compost with 4 levels, namely 0, 10, 20, and 30 tons/ha. The second factor is rice straw mulch with 4 treatment levels, namely 0, 5, 10, and 15 tons/ha. The application of coffee husk compost significantly increased plant height, number of leaves, wet weight of crown, wet weight of roots, dry weight of crown, dry weight of roots, productive branches, number of pods per sample, weight of seeds per plant, weight of 100 seeds and weight of seeds per plot. Rice straw mulching increased plant height, number of leaves, number of pods per sample, seed weight per plant, seed weight per plot and weight of 100 seeds, the interaction between coffee husk compost and rice straw mulch was not real on all parameters observed.
