Then FSIV staff led by Mr. Deng set Thinh Korea successfully tested in May 2006, following guidelines established by test documents provided by Dr. Beadle. | Ministry of Agriculture Rural Development 1 Australian Government AusAID Project name Sustainable and profitable development of acacia plantations for sawlog production in Vietnam No. 032 05 VIE REPORT FOR MILESTONES 8 Acacia pruning trials HANOI 2006 Milestone 8. Acacia pruning trials Thinning response trial Dong Hoi Drs Harwood and Beadle inspected candidate sites for thinning pruning trials at Dong Hoi Quang Binh Province Output and with FSIV scientists laid out a replicated thinning trial in a fast-growing 2-year-old clonal acacia hybrid plantation managed by the Provincial Forest Enterprise. Subsequently FSIV staff led by Mr Dang Thinh Trieu established this trial successfully in May 2006 following written trial establishment guidelines provided by Dr Beadle. All trees in the trial were pruned. The trial has for replicates with plots of four thinning treatments in each replicate. It should provide valuable data on growth response to thinning of the acacia hybrid. Total area of the trial including external buffer rows is approximately ha. The written guidelines for trial establishment and management are attached as Appendix 1. Figure 1 shows one of the thinned plots in the thinning trial shortly after establishment of the thinning treatments. Figure 1.
