DocumentThe green pathway to growth and sustainability: Sustainable management of rubber plantations
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Vietnam Rubber Group (VRG) is the largest natural rubber producer, with over 410,000 ha located in Viet Nam, Laos, and Cambodia. VRG is always aware of the responsibility for a sustainable enterprise; VRG’s efforts demonstrate an excellent example in promoting rubber sustainability.
VRG is the leading enterprise in implementing the Viet Nam Forest Certification Scheme (VFCS) and PEFC certificates in the rubber sector. In 2021, about 55,000 ha rubber plantations and 22 natural rubber processing factories were certified under the VFCS/PEFC standards; another 57,000 ha and 14 natural rubber processing factories will be certified by the end of 2021 and 300,000 ha certified by 2022.
In economic terms, VRG rubber plantations have an average yield of 1.56 ton/ha/year, which is much higher than the global average yield, through the focusing on R&D and innovative solutions, especially: new high yielding rubber clones; advanced techniques in harvesting and soil protection; intercropping and Integrated Disease Management.
VRG pays attention to environmental values by applying the best practices to reduce significant carbon emissions: increasing the use of organic fertilizers; installing solar power systems for rubber factories; developing new processing process to reduce 40% of electric usage and DO oil; using biological waste treatment; and reusing 1.5 million m3/year (25% of total water usage) of treated wastewater.
VRG demonstrates the social responsibilities and has meaningful contributions to society by improving the living conditions of VRG workers and surrounding communities (infrastructure and health care facility improvement; job and income creation).
VRG strongly considers sustainable development as the green pathway of the future and business growth; VRG looks forward to sharing the best practices and the importance of industry sustainability leadership.

ArticlePlanting bench seedlings in the field: precocity, health, genetic traceability, and homogeneity in rubber plantations
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The present work aimed to evaluate the establishment index and the initial development of rubber tree seedlings in the field, produced in pine bark substrate on suspended benches in the region of Colina/SP, Votuporanga/SP and Cassilândia/MS. Brazil. The variables evaluated were: establishment index, planting homogeneity, initial field development, and early bleeding. The results showed that the establishment index was higher than 95% due to the large amount of roots of bench seedlings and that this led to greater planting homogeneity. Regarding the development of bench seedlings in the field, this was superior compared to the development of seedlings produced in the ground, and also it was observed a bleeding precocity. In traditional plantations that use ground seedlings, bleeding takes place in the seventh year with an average of 50% of the suitable plants. In a plantation with bench seedlings, there is an anticipation of the maturity period and within six years, more than 70% of the plants are ready to enter into production.

ArticleImpact of rubber tree plantations chronosequence on soil fertility and soil organic carbon stocks, Gurafarda District, Southwest Ethiopia
XV World Forestry Congress, 2-6 May 2022

No results found.Rubber tree is one of the important commercial commodities in the globe. This study was conducted to examine the change in soil fertility and soil organic carbon stocks following conversion of forest to rubber plantation of different ages (5, 10, 15, 20 and 25 years) and coffee agroforestry. The field experiment was conducted in Guraferda district, Southwest Ethiopia. The soil samples were collected from 20× 20 m 2 plots at 30 cm depth, with three replicates at a 100 m interval. A total of 42 soil samples were taken from the three land-use types. The soil moisture content (MC), porosity, soil pH, organic carbon (OC), total nitrogen (N), available phosphorous (P), exchangeable bases, CEC (cation exchange capacity) and base saturation (B)S content of the NF (natural forest), CA(coffee agroforestry) and old age rubber plantation (RP15, RP20 and RP25) were higher than the early years of rubber plantation (RP5 and RP10). The highest soil organic carbon stocks (SOC) were recorded in NF (114.3 Mg ha -1 ), CA (112.2 Mg ha -1 ), RP25 (98.5 Mg ha -1 ) and RP20 (97.8 Mg ha -1 ). The SOC loss because of conversion of NF to RP5 (11.0 Mg ha -1 y -1), RP10 (5.3 Mg ha -1 y -1 ), RP15 (2.3 Mg ha -1 y -1 ), RP20 (0.8 Mg ha -1 y -1 ), RP25 (0.6 Mg ha -1 y -1 ) and CA (0.1 Mg ha -1 y -1 ). In general, old age rubber plantation (RP20 and RP25) showed proportional levels of soil fertility and soil organic carbon stocks compared with the natural forest and the coffee agroforestry. Since all physico-chemical characteristics were low at the early years of rubber plantation, we recommend to supplement significant proportions of nutrient to the early years of rubber plantation (0-10 years).
