Description
Coffea arabica ‘Obatã’ is a Brazilian-developed Arabica coffee cultivar derived from Timor Hybrid lines, valued for its strong resistance to coffee leaf rust (Hemileia vastatrix) and high productivity. It forms a compact to medium-sized evergreen shrub, typically reaching 2 to 3.5 meters in height, with a well-branched structure and dense, glossy dark green foliage.
The plant produces clusters of small, fragrant white flowers that give rise to green cherries, which usually ripen to a deep red. The beans are known for producing a well-balanced cup with mild to moderate acidity, good body, and a smooth, consistent flavor profile. Due to its resilience and yield potential, ‘Obatã’ is widely cultivated in commercial coffee production.
This cultivar thrives in warm, tropical to subtropical climates and performs best at moderate elevations. It prefers partial shade, fertile, well-drained soil rich in organic matter, and consistent moisture. Its disease resistance and adaptability make it a reliable option for growers in regions prone to common coffee diseases.
Germination Guide
🌍 Ethiopia
Moderate
Coffea arabica 'Obatã' is a premium arabica coffee cultivar known for quality bean production. Seeds require extended germination periods of 30-70 days and demand consistent moisture, warm temperatures (20-25°C), and high humidity to successfully develop. This variety exhibits moderate germination difficulty due to the slow, lengthy germination process characteristic of coffee seeds.

Additional notes
Use fresh seeds; viability drops significantly after 3 months unless stored at low temperature and high humidity. Seeds must maintain moisture content above 15% to remain viable.
Substrate & Container
Recommended substrate
Well-draining sandy loam with humus; 50% forest soil and 50% river sand mixture recommended
Recommended container
Seedbed, nursery tray, or individual pots with drainage holes; humidity dome recommended
Growing Tips
Soak seeds for 48 hours before sowing to accelerate germination. Keep substrate consistently moist but never waterlogged to prevent damping-off disease. Maintain humidity with a dome or plastic cover; remove it gradually after sprouting. Germinate seeds in darkness or under filtered light, maintaining temperature between 20-25°C. Use fresh seeds harvested within 3 months for best results. Place seeds flat-side down in substrate, lightly covered. Do not let soil dry out during germination phase. Radicle emergence begins around 3-4 weeks; cotyledon leaves appear at 4-6 weeks. Once seedlings emerge, gradually transition to bright indirect light.
