EFEKTIVITAS PENYEMPROTAN ABU TANDAN KOSONG KELAPA SAWIT NANO TERHADAP PERTUMBUHAN DAN HASIL PADI GOGO VARIETAS MANDEL DI TANAH ALFISOL GUNUNG KIDUL(Effectiveness Of Empty Bunches Nano Ash Palm Oil Spraying on the Growth and Results of Mandel Variety of Gogo Rice in Alfisol Soil of Gunung Kidul)Milda Aulia Rinjani RaharjoIr. Mulyono/ Ir.HaryonoJurusan Agroteknologi Fakultas Pertanian UMYABSTRACTOil Palm Empty Bunch Ash contains P, K, Ca, Si, Mg,and O nutrients each of 3.09 persen; 27.01 persen; 6.65 persen; 14.24 persen; 3.5 persen, and 45.5 persen. The aim of this study was to determinethe effectiveness of spraying nano ash of oil palm empty bunches on the growth and yield of Mandel variety Gogo rice on Alfisol soil and to determine the effectivedose and concentration in increasing the growth and yield of Mandel variety Gogo rice on Alfisol soil. The researchwas conducted usingexperimental method in polybags, with single factor treatment arranged in a completely randomizeddesign. The treatments tried isdosages and concentrations of spraying nano particles of oil palm empty fruit bunch ash with various doses and concentrations, namely a dose of 0 kg/ha and a concentration of 0 persen, a dose of 16 kg/ha and a concentration of 0.10 persen, a dose of 24 kg/ha and a concentration of 0.17. persen, a dose of 32 kg/ha and a concentration of 0.29 persen. Each treatment consisted of 3 replications, each replication consisting of 6 plants, namely; 3 sacrificial plants and 3 sample plants. So that a total of 72 polybags in total. The results showed nano spraying of oil palm empty bunches of ash at a dose of 32kg/ha and a concenyration of 0,29 persen was the effective application methot for the growth and yield of upland rice gogo of Mandel variety on Alfisol soil.
