PREVIOUS RESEARCH BREAKTHROUGHS
- RRIN in collaboration with Standard Organization of Nigeria is working to ensure implementation of the Standard African Rubber Scheme to check discounting of export rubber.
- Development of smallholder processing techniques for farm gate value addition.
- Normal and reciprocal crosses of selections introduced from rubber regions of the world has resulted in the development of 24 promising new clones, Nig 800 and Nig 900 series
- The institute has produced pure seeds of gum Arabic, capable of producing seedlings of uniform vigor and Grade I quality gum which commands highest market value relative to the low grade from a mixture of species. These seedlings are available for distribution to farmers.
- Development of rubber and gum arabic-based cropping systems using spacing techniques, crop combination, cropping sequence and fertilizer and herbicide use in crop mixtures.
- Development of integrated mini-livestock farming under mature rubber plantation.
- The exploitation of phylloplane fungi bio control agent for the control of the pathogen that causes Colletotrichum leaf disease of rubber.
- Development of protocol for the use of Vesicular-Mycorrhizal in the enhancement of plant growth and protection.
- The development of high performance natural fibre reinforced composite materials from rubber seed oil (RSO).
- Characterization of rubber seed oil for the purpose of identification and authentication of the quality of RSO.
- The development of RSO based polymeric building block for technical/engineering applications.
- The institute has carried out the synthesis, characterization and application of rubber seed oil alkyd resins, and has developed water soluble RSO alkyds low in volatile organic component (VOC) which are non-polluting and environmentally friendly coatings. These represent new areas of application of RSO which hitherto have been largely wasted.
- Production of glazing putty using rubber seed oil.
- Design and fabrication of mixer and creaming /separation tank for the production of creamed latex.
