ESTATE CROPS NEWS – This article presents Indonesia’s rubber productivity in general, technologies to increase rubber productivity, technology adoption constraints,and strategies to accelerate technology adoption, especially for smallholding farmers. Compared to other main producer countries, Indonesia’s rubber productivity is still relatively low. This is due to the majority of Indonesia’s rubber is smallholder plantation which productivity is only around 1,100 – 1,200 kg/ha/year. Increasing smallholder plantation productivity is still a major challenge for the government, researchers, academics, extension workers, plantation practitioners and all other stakeholders. The rubber research and development activities in Indonesia have produced technologies that can increase rubber productivity including superior clones, intercropping system and rubber-livestock integration to increase farmers’ incomes, and clonal typology tapping systems to optimize yield potential. The adoption of these technologies at the farm level still encounter major obstacles such as limited knowledge, capital and land area. Sustainable extension, farmer groups empowerment,and government support of capital and production resources are required to accelerate technology adoption. In the sustainable agricultural extension concept; beside the technology adoption, the roles of extension are problem-solving, training, and human resources development. The increase of smallholder plantation productivity will have a significant impact on Indonesian rubber productivity as well as farmers’ welfare.
