Penelitian ini bertujuan untuk mengetahui pengaruh ampas kopi dan pupuk kandang sapi, kambing, dan ayam terhadap sifat kimia tanah, pertumbuhan dan serapan N sawi (Brassica juncea L.) pada Tanah Entisol Samas, Bantul, Daerah Istimewa Yogyakarta. Penelitian ini dilakukan di rumah kaca Fakultas Pertanian Universitas Gadjah Mada pada April – Mei 2023. Pengamatan sawi dilakukan mulai dari penanaman sampai 33 HST. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor yaitu dosis ampas kopi (5 ton/ha dan 10 ton/ha) dan 3 macam pupuk kandang (sapi 15 ton/ha, kambing 15 ton/ha, dan ayam 15 ton/ha) dengan 12 perlakuan dan dilakukan sebanyak 3 ulangan. Hasil penelitian menunjukkan penambahan ampas kopi dan pupuk kandang menaikkan pH, C-Organik, KPK dan Nitrogen total tanah. perlakuan kombinasi pupuk kandang ayam dan ampas kopi 10 ton/ha memberikan pengaruh terbaik terhadap serapan N tanaman sawi.

This research aims to determine the effect of coffee grounds and cow, goat and chicken manure on soil chemical properties, growth and N uptake of mustard greens (Brassica juncea L.) in Samas Entisol Soil, Bantul, Special Region of Yogyakarta. This research was conducted in the greenhouse of the Faculty of Agriculture, Gadjah Mada University in April – May 2023. Observations of mustard greens were carried out from planting until 33 HST. This research used a factorial Completely Randomized Design (CRD) with 2 factors, namely the dose of coffee grounds (5 tonnes/ha and 10 tonnes/ha) and 3 types of manure (cow 15 tonnes/ha, goat 15 tonnes/ha, and chicken15 tonnes/ha) with 12 treatments and carried out in 3 replications. The research results showed that the addition of coffee grounds and manure increased pH, C-Organic, KPK and total soil nitrogen. The combination treatment of chicken manure and coffee grounds at 10 tons/ha had the best effect on N uptake of mustard plants.
