Abstract

This study assesses the positive effects of inter-planting Coffea arabica and Machilus odoratissima Nees over seven years in small-scale farms in Huong Hoa district, Quang Tri province, Vietnam. The results show that the environmental conditions for growing and developing the coffee trees improve in the area of mix-planting Coffea and Machilus. Compared with monoculture farms, the inter-planting farms experience the wind speed decreased to 1.67 m·s–1, the soil moisture increased by 5.1%, and the soil temperature decreased by 3.6 °C. The coffee yield increases by approximately 7.5%. In addition, Machilus products also contribute to economic efficiency and the sustainability of coffee farms (716.52 USD/ha). This could be considered financial support to the farmers to maintain the coffee plantations in harsh weather conditions or in uncertain prices of productions.
