Macadamia nuts are a high-value crop grown in many countries, including Australia, South Africa, Hawaii, China, and Southeast Asia. The production of macadamia is expected to increase in the coming years, with estimates reaching 240,000 tons in 2020 and 600,000 tons by 2030. Growing macadamia requires specific ecological conditions, including a cool and humid climate, and the right variety of plants should be chosen for optimal production efficiency.
