All Research and Extension departments of RRISL provide advice on all aspects of rubber agronomy and technology to stakeholders.In addition it also assists academic programs of universities and other higher education institutions by supervising students and human resource development programs of various other organizations by training teachers and stakeholders.When analytical services are provided, a nominal fee is charged to cover up basic costs.
