The Rubber Development Department’s official website is an important platform for sharing information and resources about the rubber industry in Sri Lanka. One key feature of the website is the RRI Publications Tab, which provides access to advisory circulars created by the Rubber Research Institute of Sri Lanka (RRI). These circulars are based on detailed research and offer clear advice on all major areas of rubber cultivation and processing. They are an essential resource for rubber growers, manufacturers, and other stakeholders to improve productivity and sustainability. The topics covered in these circulars include Budwood Nursery Management, Fertilizer for Rubber, Manufacture of Latex Crepe, Production of Budded Plants, RSS (Ribbed Smoked Sheets) Manufacture, Soil Conservation, Collection and Preservation of Latex, Manufacture of Rubberized Coir Mattresses, Field Establishment and Immature Upkeep, Management of White Root Disease, Tapping and Use of Rainguards, Rubber Based Farming Systems, and Manufacture of Cast Products. By making these circulars available online, the Rubber Development Department ensures that stakeholders have easy access to reliable, science based guidelines to improve practices in the rubber sector. These publications are crucial for increasing efficiency, solving challenges, and introducing modern methods across the industry.
