This study assessed the active effects of inter-planting Coffea arabica and Machilus odoratissima Nees, planted over seven years in small-scale farms in Huong Hoa district, Quang Tri province, Vietnam; purpose to evaluate the effectiveness of inter-planting farm of Coffea arabica and Machilus odoratissima in the study site. The results show that the environmental conditions for growing and developing the coffee trees have been improved in the area of mix-planting Coffee and Machilus. The coffee productivity, as a result, has also been increased. In comparison with the living condition at the monoculture farms, wind speed was reduced to 1.67ms-1, soil moisture was increased by 5.1% and soil temperature was decreased by 3.60C at the inter-planting farms. The coffee productivity correspondingly increased by approximately 7.5%. In addition, the value of Machilus products contributed to economic efficiency and economically ensured the sustainability of coffee farms. It also shows that the harvesting Machilus products after seven years of planting contributed over 716.52 USD/ha to the farmer incomes. This could be considered as an economic support to the farmers to maintain the coffee plantation in hash weather conditions or in uncertain prices of productions.
