Abstract


The aimed of this study was to determine the growth and the productivity of sorghum planted in Merapi eruption soil which was affected by addition with various levels of organic fertilizer. The treatments given was an organic fertilizer 5 and 10 ton/ha. Analysis was conducted on the production, chemical composition, and In vitro digestibility. Data was analyzed using anova analysis on Completely Randomized Design (CRD) and the difference between means was continued with Least Signi cant Difference (LSD) test. The result showed that plant height, dry matter production, In vitro digestibility dry matter affected (P<0.05) by addiction of organic fertilizer in Merapi eruption soil. Plant height increase for 87.55 cm to 118.12 - 126.00 cm, dry matter production for 2.82 ton/ha to 5.20 - 5.68 ton/ha, and In vitro digestibility dry matter for 65.39% to 66.37 - 69.20%. Based on the result of study, addition an organic fertilizers 5 and 10 ton/ha on Merapi eruption soil increased the growth and the productivity of sorghum.
