摘要：To support increased rice production, the government is trying to increase the use of superior varieties in farming. In line with this, a study has been carried out aimed at analyzing developments, problems in the distribution, and farming of improved rice varieties. The research was conducted in Central Java Province in 2020. The research sample consisted of 30 rice farmers and various institutions related to this study. Data analysis was carried out quantitatively and descriptively qualitatively. The results of the study showed that the distribution of superior rice varieties (2015-2019) was dominated by Ciherang (31.5%) and IR64 (18.1%) varieties, while the new superior variety Inpari had only 3.9% of the spread. Problems faced in the distribution of superior rice varieties include: limited availability of good quality seeds, low yield productivity, and insufficient resistance to pests and diseases. The results of rice farming analysis at MT-II 2020, farming profits for the Ciherang and Inpari 32 varieties, respectively, are IDR. 9.5 million and in IDR 11.0 million per hectare per season. In order to increase the spread of improved rice varieties, it is necessary to support the provision of seeds with high productivity potential, farming pilots and support from government programs.
