At Ea Yong commune, Krong Pac district, Daklak province, Vietnam, we evaluated four Robusta coffee intercropping models (Coffea canephora Pierre var. Robusta) with perennial trees on Rhodic ferrasol soil and tropical environment. Intercropping coffee with Siamese cassia (Cassia siamea Lam.), intercropping coffee with durian (Durio zibethinus Murr.) 9 x 9 m, and intercropping coffee with durian 9 x 6 m are the models. The goal of this study is to see how well intercropping fruit trees can return biomass to the soil over time while also providing additional income. The result: green biomass increases from 71.6 tons.ha-1 to 101.4 tons.ha-1 (intercrop coffee with Siamese cassia) or 176.4 tons.ha-1 (intercrop coffee with durian 9 x 9 m) or 178.6 tons.ha-1 (intercrop coffee with durian 9 x 6 m); the yield in the intercrop model of coffee with durian (9 x 9 m) is reduced by 300 kg.ha-1 of dry coffee beans (4,120 kg.ha-1). These models, on the other hand, generated between 22 and 23 tons.ha-1 of durian fruits, resulting in significant profitability and a considerable amount of green biomass. Farmers are encouraged to intercrop coffee with perennial fruit trees rather than growing solely coffee or intercropping with forestry trees.
