1R&D FOR RUBBER INDUSTRY IN VIETNAM PHAN THÀNH DŨNGRubber Research Institute of VietnamPanel 3 : Current challenges in research for smallholder rubber plantations
2INTRODUCTIONRubber tree (Hevea brasiliensis Mull.-Arg) was introduced into Vietnam by Dr. Yersin, French scientific, and has been commercially since 1906 in Southeast Region.By 1976, rubber area was ha only produced ton (0,52 ton/ha). In 2007, total rubber area accounted upto ha and gave the production tons (1,612 ton/ha)
3Introduction of rubber tree into Vietnam rubber seeds germinated Kew Gardens (England)2, Rubber tree introduced intoVietnam.533. Rubber seeds arrived to Ceylon414. 22 seedlings transferred toSingaporeWickham collected rubber seedsIntroduction of rubber tree into Vietnam
7Apllied technique for rubber cultivation Technique is introduced from various rubber planting countries (via. conference, workshop, short training…) then modificed and domestically applied.Result of R&D conducted by RRIV and VRG.Technical guideline for rubber planting sectors
8Rubber cloneRubber clone plays an inportant role for development of local rubber industry.Rubber clones have been introduced from other countries (Malaysia, Indonesia…) and localy beeded by RRIV (RRIV và LH).Clonal rubber planting recommendetion is issued by VRG based on clonal trial network of RRIV.

13Advanced Planting Material Polybag with 1-3 whorls is widely planted in large scale that could reduce immature period 1-2 year and increase tappable tree…Advanced planting material is suitable for untraditional area such as Highlands, Central Coastal, North.
20ExploitationLow intensity tapping system: d3 tapping interval and latex stimulant are widely applied.Raingard: increment of tapping day and reduce panel diseases,…Gas stimulation: yield increment 20-50%, especially at early tapping season.
23Crop protection Weed management by herbicide and others. Seven major diseases recorded: Corynespora leaf fall, Oidium leaf fall, Collectotrichum leaf fall, Black stripe, Brown root…Protocol for disease control recommended by RRIV and VRG.
33Rubber processing line RSS is most suitable for rubber small holding (Low cost of installation, maintaining, effluent treatment…).Pilots set up by RRIV for various rubber small holder.Pilot run by rubber small holding group (coperrative).
34RRIV contribution Conduct R&D on agronomy and processing. Carry out training for various local rubber sectors.Carry out collaboration researches with the organizations such as: IRRDB, Rubber Research Institutes, WB&AFD project…
35Experience for development of rubber small sector Rubber clone (supply and inspection by Government Bodies).Soil survey and classification (Institute or Province).Planting material (Certificated Bodies).Fertilizer and pesticide supplied (good quality and quantity)Appropriated tapping system (Demonstration).Suitable processing line and marketing information (Pilot and Rubber market).
