The impact of factors affecting the productivity of Acacia hybrid forest in Thua Thien Hue

Abstract

Hybrid Acacia is the major species in the forest plantation in Thua Thien Hue province. This study was conducted to analyze and evaluate the impact of factors affecting the productivity of Acacia hybrid forest those are grown and harvested in Thua Thien Hue. The study has collected data in 327 plots, of the 38 communes in 6 districts where Acacia hybrid have planted and harvested. The study has analyzed and evaluated 9 factors including 5 site condition factors (including soil type, soil thickness, soil texture, slope, and elevation), two climate factors (including total rainfall and annual temperature) and two
socio-economic factors (including forest cultivation model and forest
management model). The results showed that all the studied factors have a significant impact on yield/productivity of Acacia hybrid forest in the Thua Thien Hue province with the significance level is less than 5%. However, the management factor is not significantly affected. The study suggested that households need to be supported and invested in afforestation with intensive cultivation model because the productivity of intensive plantation is nearly doubled compared to the extensive cultivation model. It is needed to study the aggregate effect of these factors and build a productivity map for the Acacia hybrid forest by different planting/cultivation models in Thua Thien Hue
province in order to facilitate the management and sustainable development ofAcacia hybrid forest in Thua Thien Hue province.
