With over 184,500 hectares of coffee—mostly robusta—yielding more than 400,000 tons of green beans annually, Đắk Lắk is Vietnam’s largest coffee-producing province. In recent years the province has applied a wide range of scientific and technical innovations, from variety breeding and cultivation practices to plant protection and processing, driving strong economic results and improving farmers’ livelihoods.
Advanced Variety Breeding and Selection
Table of Contents
Robusta Clonal Varieties
According to Dr. Lê Ngọc Báu, Director of the Western Highlands Agro-Forestry Science and Technology Institute, robusta is a long-lived, cross-pollinating plant, so variety selection focuses on elite mother plants and vegetative propagation.
-
Beyond the Ministry-approved clones 4/55 and 1/20, Đắk Lắk has introduced nine more clonal lines—TR4, TR5 … TR9, TR11, TR12, TR13—bred and selected by the Institute, including five (TR4–TR8) already regionally approved.
-
These clones deliver 4.5–7.3 tons of green beans per hectare.
-
Bean size advantage: 100 beans weigh 17.5–20.6 g, compared with 13–14 g in older varieties.
-
Over 70% of beans are screen size 16 or above, ideal for top-grade coffee.
-
Exceptional disease resistance: coffee leaf rust ratings as low as 0–0.1%.
Today these clonal varieties are supplied as grafted plants to farms and coffee businesses across the Central Highlands.
Cost-Effective Hybrid Seeds
To reduce seedling costs, the Institute has developed hybrid seeds from selected clones. Field trials show these multi-line hybrids match the yield of grafted clonal plants and adapt well to local conditions.
Arabica Innovation
For arabica, the Institute has created hybrids between Catimor and wild Ethiopian arabicas, selecting ten promising hybrids (TN1–TN10).
-
TN1 and TN2 have already been regionally certified.
-
These hybrids combine high yield, good cup quality, and leaf-rust resistance.
Integrated Farming Practices
Working with Đắk Lắk province, the Institute has guided farmers—including many ethnic minority communities—to apply integrated technical measures:
-
Quality seedling selection
-
Windbreak and shade tree planting
-
Mulching and efficient irrigation
-
Pruning and canopy shaping
-
Constructing basins to capture plant residues
-
Balanced fertilization and Integrated Pest Management (IPM)
Measurable Benefits
-
Fertilizer cost savings: 700,000–1,000,000 VND per hectare
-
Water savings: 400–600 m³ per hectare each season
-
Stable yields and environmental protection
Farm Diversification and Modern Processing
Farmers and coffee enterprises are also:
-
Intercropping high-value fruit trees and black pepper to increase income per hectare.
-
Shifting from traditional dry processing to modern wet processing, which improves product quality and international competitiveness.
Toward a Sustainable, Profitable Coffee Industry
Đắk Lắk continues to collaborate with the Western Highlands Agro-Forestry Science and Technology Institute and universities to adopt new scientific and technological advances in coffee cultivation and intensive farming.
The province aims to:
-
Develop a cleaner, more sustainable, and more profitable coffee industry.
-
Raise living standards for coffee producers.
-
Strengthen its position as Vietnam’s leading coffee hub.
