Plukenetia zenkeri Pax, commonly known as the Sacha inchi plant, is a plant species belonging to the Euphorbiaceae family. The plant is native to South America and mainly cultivated in Peru, Colombia, Ecuador, and Thailand. It is an ancient crop that has been used for centuries due to its numerous health benefits.
The Common Names of Plukenetia zenkeri Pax
The plant is commonly known by a variety of names in different regions. In Peru, it is known as 'Sacha inchi,' which means 'mountain peanut' in Quechua, and sometimes referred to as 'Inca peanut' or 'jungle peanut.' It is also referred to as 'Maní del monte' in Colombia, which means 'peanut of the mountain,' and 'Kwane' in Thailand.
The Uses of Plukenetia zenkeri Pax
The Sacha inchi plant has numerous uses, from its seeds, oil, to the leaves. The seeds are edible and have a nutty flavor, similar to peanuts. They are usually consumed roasted, toasted, or raw and are highly nutritious, containing high levels of protein and omega-3 fatty acids. The oil extracted from the seeds is used in the cosmetic industry for its moisturizing properties and in cooking due to its high smoke point. The leaves are also used in traditional medicine for treating various ailments.
The General Appearance of Plukenetia zenkeri Pax
The Sacha inchi plant is a climbing perennial herb that grows up to six meters in height. The leaves are green and heart-shaped, with pointed ends and serrated edges. The flowers are small and white or light pink, and the fruits are oval-shaped capsules that contain seeds. The seeds are approximately 1.5 to 2 centimeters in diameter, and when harvested, they are dark brown to black in color. The plant is adaptable to different climates, growing in both tropical and subtropical regions.
Light Requirements
Plukenetia zenkeri Pax prefers bright, indirect sunlight. It can thrive in partial shade, but too much shade can lead to stunted growth and poor fruit production. Additionally, too much direct sunlight can scorch the leaves and cause irreversible damage.
Temperature Requirements
The ideal temperature range for Plukenetia zenkeri Pax is between 20-30°C (68-86°F). While it can tolerate slightly cooler temperatures, prolonged exposure to temperatures below 15°C (59°F) can be detrimental to the plant's health. On the other hand, temperatures above 35°C (95°F) can cause wilting and stress to the plant.
Soil Requirements
Plukenetia zenkeri Pax thrives in well-draining soils that are rich in organic matter. It prefers a slightly acidic soil pH between 5.5-6.5. The soil should also be able to hold moisture without becoming waterlogged. Sandy loam or loamy soil is ideal for this plant.
Cultivation of Plukenetia zenkeri Pax
Plukenetia zenkeri Pax is a plant that can be grown in both indoor and outdoor settings. It is a relatively fast-growing plant that requires slightly acidic soil with good drainage to thrive. For optimal growth, it requires a temperature range of 20-30°C and humidity levels of 60-80%. Ideally, the plant should be grown in a partially shaded position to prevent sunburn.
Watering Needs
Plukenetia zenkeri Pax requires regular watering to thrive, especially during its growing season. The soil should be kept moist but not waterlogged. It's crucial to avoid overwatering, which can lead to root rot and subsequent plant death. When watering, it's necessary to ensure the water reaches the plant's root zone to encourage deep root growth and proper nutrient uptake.
Fertilization
Plukenetia zenkeri Pax requires regular fertilization to grow and produce fruit. It's essential to use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. The best time to apply fertilizer is during the growing season when the plant is actively growing. Avoid overfertilizing, as this can lead to leaf burn and stunted growth. If you notice yellow leaves or stunted growth, it may indicate a lack of nutrients, in which case you should apply a fertilizer with a higher nitrogen content.
Pruning
Pruning is essential in promoting bushy growth and fruit production in Plukenetia zenkeri Pax. Typically, the plant is pruned during the dormant season, with most pruning done to shape or control the plant's size. It's essential to prune away any damaged or diseased branches promptly. Additionally, removing spent flowers and fruit can also help encourage new growth and increase fruit production.
Propagation of Plukenetia zenkeri Pax
Plukenetia zenkeri Pax, also known as the sacha inchi plant, is a popular crop in several parts of the world. Propagation of this plant can be achieved through different methods, including seed propagation and vegetative propagation.
Seed propagation
Seed propagation is the most common method used to propagate the Plukenetia zenkeri Pax plant. Sow fresh seeds in well-drained soil, about 2 cm deep, and keep them moist. Seeds should germinate within 14 to 21 days, and seedlings will be ready to transplant after 6-8 weeks. Seedlings should be planted in the field or garden bed after the last frost.
It is important to note that the Plukenetia zenkeri Pax seeds have a hard coat that needs to be removed before sowing. To improve seed germination, soak the seeds in water or use sandpaper or a sharp blade to scratch the outer layer of the seed.
Vegetative propagation
Vegetative propagation is another method to propagate Plukenetia zenkeri Pax, which involves the use of plant parts other than seeds. This method can be used to obtain plants that are genetically identical to the parent plant.
The vegetative propagation method commonly used for the Plukenetia zenkeri Pax plant is stem cutting. Choose healthy, disease-free stems and cut them into 10-15 cm sections. Remove the leaves from the bottom half of the stem, dip the end in rooting hormone, and plant the cutting in a pot filled with well-draining soil. Keep the soil moist and in a warm, bright place until new roots have developed. Transplant the rooted cuttings into the desired location after 4-6 weeks.
Disease and Pest Management for Plukenetia zenkeri Pax
Plukenetia zenkeri Pax, commonly known as Sacha Inchi, is a nutritious plant that is highly valued for its oil content. Like any other plant, Sacha Inchi is susceptible to diseases and pests that can cause significant damage if not managed effectively. Here are some of the common diseases and pests that might affect Sacha Inchi and ways to manage them.
Diseases
Sacha Inchi is vulnerable to fungal diseases, such as root rot, stem rot, and leaf spot. Root rot is caused by waterlogging and poor drainage, which leads to the decay of the plant's root system. Stem rot and leaf spot are primarily caused by fungus, which thrives in warm and humid conditions.
To manage fungal diseases, it is essential to maintain proper sanitation practices, such as removing infected plant debris and avoid overwatering the plant, providing well-drained soil. Also, applying fungicides such as Copper Fungicide and Daconil are effective in managing fungal diseases in Sacha Inchi.
Pests
Sacha Inchi is also vulnerable to various pests, including mites and aphids. These pests suck the sap from the plant, leading to stunted growth and wilted leaves.
One way to manage pests is to introduce natural predators like ladybugs that feed on aphids. Horticultural oils such as Neem oil act as organic pesticides to repel pests. Spraying an insecticidal soap solution on the plant can also help manage the pests.
In conclusion, preventing diseases and pests in Sacha Inchi plants requires proper sanitation practices, timely care, and effective management techniques. By following these measures, plant growers will be able to maintain healthy and productive plants, yielding good returns.
