Support farmers to access to finance that enable them undertaking coffee rejuvenation with sustainable practices and offset for income disruption during rejuvenation period. for both Indonesia, Uganda and other countries, with Robusta coffee nematode In summary, problems have had to use nematode resistant clonal rootstocks to ensure replanting success. Therefore, support to research, multiplication, and dissemination of coffee lines resistant to CWD, the control of pests and diseases capacity building is necessary. SECTION C. COFFEE REJUVENATION PRACTICES IN VIETNAM 1. Agronomic Practices Grafting Coffee grafting is agronomically viable for healthy old trees usually not more than 20 years old - if termites not a problem and trees are in good health and vigorous. The purpose of grafting is to replace the old varieties that have low yields, leaf rust affected and small bean size. Shoot grafting was undertaken to replace the old parent variety with new varieties with high yield, large bean size (Bean type R1 > 65 %), high resistance to leaf rust to increase productivity and economic efficiency by about 15-20 %. The old variety becomes the rootstock which we say is top worked to a new high performance TR clonal or hybrid variety. There are two grafting options that commonly applied in practice: Full grafting: farmers apply full grafting of their coffee farm with 1 year (100% model) Partial or rolling grafting: farmers grafting 50% of their coffee garden in the first year and the rest in the second year (50% model). According to coffee farmers survey’s result, in Lam Dong, 59.7% of successful households had conducted grafting of coffee gardens under 20 year-old. The time for cutting the trees for grafting is mainly from November to May next year and the time for grafting begins mainly from February to July. The highest ratio of successful grafting is from Feb-Apr (account for 59.7% of the successful households). The grafting time in the dry season and beginning rainy season using the close grafting method has the highest survival rate, reduced costs and ease of care during and after grafting. The coffee farmers survey data shows that
