ArticleJournal articlePlanting bench seedlings in the field: precocity, health, genetic traceability, and homogeneity in rubber plantations

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.

DocumentOther documentThe green pathway to growth and sustainability: Sustainable management of rubber plantations

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.

No results found.The purpose of this paper is to present research results relative to impacts of Climate Change on natural rubber production, potential means of adaptation and contribution of rubber to livelihoods resilience to climate change following a recent workshop organized by IRSG in collaboration with 2 CIFOR/FTA, IRRDB and CIRAD. Climate change already impacts rubber production. In some regions longer dry seasons and more variable precipitations threaten the survival of young plants. Rubber has never been planted in areas with an average temperature higher than 28°C; as latex flow after tapping depends on temperature, higher temperatures may have a severe impact on production. Abnormal rains can also disrupt tapping. These modifications will drive a shift of climatically favourable areas. Most pests and diseases affecting rubber are strongly influenced by climate conditions. Climate change is thus likely to modify their distribution and impacts. Without adaptation natural rubber production is projected to decline, in a context of otherwise increasing rubber demand. Three types of adaptation measures can be mobilized: management, breeding, and medium-term planning of plantation renewals and expansion in marginal areas. Management measures include partially shading young plants, mulching them, partial irrigation and life-saving irrigation to address increased risks of drought as well as adopting measures that reduce runoff. Systematic use of rain guards can address impacts of heavy rains on tapping. Better monitoring, prevention and early intervention can reduce damage by pests and diseases. Genomic assisted selection and collection of wild germplasm can support breeding progress towards high yielding, climate resilient and disease resistant clones. Such measures need to be supported by policies promoting the renewal of plantations and changes of practice. As shown by Sri Lanka the NationalAdaptation Plan (NAP) can offer opportunities to develop an integrated approach to adaptation of rubber to climate change and to contribute to the adaptation of smallholders.
