  1. R&D FOR RUBBER INDUSTRY IN VIETNAM PHAN THÀNH DŨNG Rubber Research Institute of Vietnam Panel 3 : Current challenges in research for smallholder rubber plantations

  2. INTRODUCTION • Rubber 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 76.600 ha only produced 40.200 ton (0,52 ton/ha). In2007, total rubber area accounted upto 549.600 ha and gave the production 601.700 tons (1,612 ton/ha)

  3. 2. 2000 rubber seeds germinated Kew Gardens (England) 2 5. 1897, Rubber tree introduced into Vietnam. 5 3 3. Rubber seeds arrived to Ceylon 4 1 4. 22 seedlings transferred to Singapore 1. 1876 - Wickham collected 70 000 rubber seeds Introduction of rubber tree into Vietnam

  4. Rubber cultivation area in Vietnam

  5. RUBBER AREA UNDER CULTIVATION 549.600 ha 2007 2006 490.200 ha 1975 75.200 ha 1945 138.400 ha 1920 7.077 ha 1906 First rubber estate established 1897 Introduction of rubber tree

  6. AVERAGE YIELD 2007 1,612 kg/ha 2005 1.440 kg/ha 2000 1.222 kg/ha 1995 849 kg/ha 1990 714 kg/ha 1985 753 kg/ha 1980 703 kg/ha

  7. Apllied 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

  8. Rubber clone • Rubber 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.

  9. Clonal Planting Recommendation (2006-2010)

  10. Rubber clonal trial

  11. Rubber clones breeded by RRIV

  12. LH 88/236 14 year old

  13. Advanced 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.

  14. Advanced planting materials

  15. Rubber nursery

  16. RRIV 4, 3 year old

  17. PB 255 RRIV 4

  18. Soil and Nutrient Management • Soil survey and classification. • Soil and leaf analysis for recommending fertilizer dosage.

  19. New rubber planting in hilly area

  20. Exploitation • Low 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.

  21. Raingard and stimulant application

  22. Gas stimulant system (RRIMFLOW)

  23. Crop 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.

  24. Oidium leaf fall

  25. Oidium leaf fall

  26. Collectotrichum leaf fall

  27. Phytopthora leaf fall

  28. Corynespora leaf fall Green shoot Defoliation

  29. Pink disease

  30. Dieback caused by Botrydiplodia spp

  31. Bark disease caused by Botrydiplodia spp

  32. Tapping panel destroyed by black stripe

  33. Rubber 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).

  34. RRIV 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…

  35. Experience 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).

  36. Thank you for your attention
