Abstract

Research of Response of Kinds Fertilizer and Varieties of Rice Growth and Yield In System of Rice Intensification aims to find response range of fertilizers and the varieties of the growth and yield of rice in System of Rice Intensification. Research has been carried out in the villages of Margokaton, Seyegan, Sleman Regency in November 2009 until March 2010. The height of a place of 300 meters above sea level with a type of soil regosol. Research is 3 X 3 factorial experiment that compiled using Randomized Completele Block Design with three replicates. The first factor of fertilizer that organic fertilizers, inorganic fertilizers, organic fertilizers and combination with inorganic fertilizers. The second factor is the local varieties of rice varieties (Rojolele) and hybrid varieties (Ceherang and IR-64). The result showed that the treatment combination of organic fertilizer with inorganic fertilizers provide growth and better yield compared to the treatment of organic fertilizer and inorganic fertilizers. Varieties rojolele give quantity and quality results better than varieties IR 64 and Ciherang Keywords: SRI (System of Rice Intensification), Variety, Fertilizer
