Booth 7 avocado has high yield, good fruit quality, good appearance, and late harvesting season, which is suitable for Central Highlands. To contribute to the development and improvement of avocado production, the research experiments to complete the intensive process of Booth 7 avocado were carried out from 2018 to 2019 in Dak Lak and Lam Dong provinces. The results showed that the appropriate fertilizer dose recommended for adult phase is 1.0 N + 0.3 P2O5 + 0.9 K2O + 0.1 CaO kg/tree at average yield from 50 to 60 kg/tree. Watering several times with a cycle of 10 days (12 times a year), an amount of 500 – 600 liters/tree at the flowering period and exponential fruit growth is necessary, it gives the highest yield. The treatment with Matalaxyl (Mataxyl 500WG) + Trichoderma spp. (Vi – DK) had the highest effect on the disease incidence of Phytophthora root rot disease, followed by Phosphorous acid (Agri-Fos 400SL) + Trichoderma spp. (TricôĐHCT-Phytoph).
