The plant prefers a warm, humid, and bright environment with a temperature ranging from 25-30°C. It grows well in all types of soils, but well-drained loamy soils are the best. Propagation is done mainly through seed germination. The seeds should be sown at a depth of 2-3 cm with a spacing of about 2 meters. The plant takes about 2-3 years to mature.Watering Needs
The Robusta coffee plant grows well in a well-drained but moist soil environment. It requires regular watering to maintain a constant moisture level in the soil. The amount and frequency of watering may vary depending on the season. During the growing season, it should be watered twice a week, while in the dormant season, watering should be done sparingly. However, it is essential to avoid waterlogging or overwatering in the plant as this can lead to root rot and stunted growth.Fertilization
Fertilization is crucial for the proper growth and development of the Robusta coffee plant. Nitrogen is the most critical nutrient required by the plant, and it should be applied regularly during the growing season. Other necessary nutrients required include phosphorus, potassium, and micronutrients such as calcium, magnesium, and iron. Fertilizers can be applied in the form of organic or inorganic fertilizers. However, it is recommended to use organic fertilizers as they are environmentally friendly and help enhance soil fertility and health.Pruning
Pruning is necessary to promote the growth of new shoots and improve the quality and yield of coffee berries. It is recommended to prune the plant during its dormant season once every year. The ideal time for pruning is between October and November. During pruning, the dead and diseased branches should be removed, leaving only the healthy ones. Also, the lateral branches should be pruned to promote a more robust central stem. However, excessive pruning should be avoided as it can lead to stunted plant growth and reduced productivity.Propagation of Coffea canephora Pierre ex A.Froehner forma sankuruensis De Wild.
Coffea canephora Pierre ex A.Froehner forma sankuruensis De Wild., also known as Congo coffee, is a species of coffee plant that is native to the Democratic Republic of Congo. The plant is typically grown in tropical regions and is propagated through several methods.
Seed Propagation
One of the primary methods of propagating Coffea canephora is through seed propagation. The seeds can be directly sown in the soil or germinated in a nursery. Before sowing the seeds, it is important to clean them and remove any defective ones. The seeds can be soaked in water for 24 hours before planting to improve germination rates. Seedlings typically emerge within 4-6 weeks.
Cutting Propagation
Coffea canephora can also be propagated using stem cuttings. Cuttings from mature plants are taken and planted in the soil or in a nursery. The cuttings should be about 15-20 cm long and have 2-3 nodes. The leaves should be removed from the lower part of the cutting, and the cutting should be planted in a well-draining medium. The cuttings root within 2-3 months and can be planted in their final position.
Air Layering Propagation
Air layering is another method of propagating Coffea canephora. This method involves making a small incision in the stem of the plant and wrapping it with moist sphagnum moss and plastic. The moss is kept moist until roots begin to form, after which the stem can be cut and planted in a container or in the soil. This method is typically used for larger plants with thicker stems.
Grafting Propagation
Grafting is a common method of propagating Coffea canephora onto robusta coffee rootstock. This is done by taking a scion from a Coffea canephora plant and attaching it to the rootstock of a robusta coffee plant. The two plants are then bound together until the scion begins to take root in the rootstock. This method is typically used for commercial production.
