Micro-phytoclimatic conditions in coffee plantations under influence of the intercropping tree
2001
Nguyen Van Thuong
A phytoclimatic investigation aiming at determining conditions of radiation, humidity and thermal status in number of coffee plantations under canopies of the trees was carried out some places in Daclac province. The results showed that trees such as rubber, cinnamon, cashew and durian could decrease more than 70 percent of the solar radiation coming to the coffee canopies, thus decreased strongly the coffee yields. In the coffee plantations with the intercropping trees, the wind speed was decreased between 41 percent - 80 percent; the air temperature was between 2oC 4oC lower and the relative humidity was between 5 percent - 15 percent higher in comparison with in pure standing coffee plantations.
