ABSTRACT
Research on the effect of liquid organic fertilizer concentration of gliricidia leaf on growth and yield of red bean was conducted in experimental garden of Gunung bulu, Argorejo, Sedayu, Bantul with altitude of 114 mdpl with vertisol soil type and Agrotechnology Laboratory of Mercu Buana University of Yogyakarta, starting from April until July, 2017. This research was design in the form of experimental method. The treatment factor was a single factor, it was concentration of liquid organic fertilizer of gamal leaf consisting of 4 levels of experimental treatment unit arranged in Completely Randomized Group Design (RAKL) with 3 repetitions, so that the number of experimental unit was 12 units. The treatment was in the form of giving liquid organic fertilizer of gamal leaf with concentration 0%, 10%, 20%, and 30%. The research results showed that: (i) Liquid organic fertilizer of gamal leaf able to increase the growth and yield of red bean. (ii) Provision of liquid organic fertilizer of gamal leaf with concentrations of 30% was the best concentration for growth and yield of red bean.
Keywords: Red bean, growth, yield, liquid organic fertilizer, gamal

INTISARI
Penelitian tentang pengaruh konsentrasi pupuk organik cair daun gamal terhadap pertumbuhan dan hasil kacang merah dilaksanakan di kebun percobaan Gunung bulu, Argorejo, Sedayu, Bantul dengan ketinggian tempat 114 mdpl dengan jenis tanah vertisol dan di Laboratorium Agroteknologi Universitas Mercu Buana Yogyakarta mulai bulan April sampai bulan Juli 2017. Penelitian ini merupakan penelitian dengan metode percobaan (eksperimen). Faktor perlakuan adalah faktor tunggal, yaitu konsentrasi pupuk organik cair daun gamal yang terdiri atas 4 aras perlakuan unit percobaan ditata dalam Rancangan Acak Kelompok Lengkap (RAKL) dengan 3 ulangan, sehingga jumlah unit percobaan keselarasan ada 12 unit. Perlakuan berupa pemberian pupuk organik cair daun gamal dengan konsentrasi 0%, 10%, 20%, dan 30%. Hasil penelitian menunjukan bahwa: (i) Pupuk organik cair daun gamal mampu meningkatkan pertumbuhan dan hasil kacang merah. (ii) Pemberian pupuk organik cair dengan konsentrasi 30% merupakan konsentrasi terbaik untuk pertumbuhan dan hasil kacang merah.
