Economic Efficiency of Macadamia and Coffee Intercropping on Basaltic Soils in Krong Nang District, Dak Lak Province

The economic efficiency of macadamia and coffee intercropping at different planting time in Krong Nang district, Dak Lak province was evaluated. The research results showed that the economic efficiency of the macadamia and coffee intercropping was significantly higher than coffee monoculture. Intercropped with 185 macadamia trees per hectare of coffee did not clearly affect coffee yields (4.10 to 4.35 tons coffee bean ha-1). In addition, additional 2.81 tons macadamia nuts ha-1 year-1 were harvested, resulting in increased total income of macadamia and coffee intercropping to 193.56% compared to the coffee monoculture. In the macadamia and coffee intercropping field at the 9th year of planting, gross production reached VND 396.17 million and the net profit reached VND 294.47 million ha-1 year-1, while the net profit of the coffee monoculture was from 92.87 to 100.37 million VND ha-1 year-1. The capital efficiency of the macadamia and coffee intercropping field at the 4th and 9th year of planting was 2.34 and 3.9 times, respectively, while the capital efficiency of pepper and coffee intercropping was 2.73 times.
