Light Requirements
The plant Dolichos elatus Baker requires full sun with an average of 6 to 8 hours of direct sunlight daily to grow and develop properly. This plant prefers bright, sunny outdoor locations and does not tolerate heavy shades. Therefore, it should be planted in well-exposed areas.
Temperature Requirements
The ideal temperature range for the growth of Dolichos elatus Baker is between 68 °F to 85 °F. This plant cannot tolerate frost, so it should be planted in regions that have a tropical or subtropical climate. Frost damages the leaves and can cause the death of the plant.
Soil Requirements
Dolichos elatus Baker needs a well-drained soil that is rich in organic matter and slightly acidic. The optimal pH range for the growth of this plant is between 5.5 to 6.5. The soil should also be sufficiently moist, but not saturated or waterlogged, as it may cause root rot leading to the death of the plant. The plant prefers loam or sandy loam soils, which are fertile and have good drainage.
Cultivation Methods for Dolichos elatus Baker
Dolichos elatus Baker, also known as the Indian Long Bean, is a warm-climate vegetable plant that requires proper soil preparation before planting. The plant prefers a loamy, well-drained soil that is rich in organic matter. It grows well in a moderate temperature range of 25-35°C during the day and 15-20°C during the night.
The seeds should be soaked overnight in clean water to soften the seed coat and enhance germination. Plant the seeds 2-3 cm deep in rows that are 45-60 cm apart. Dolichos elatus Baker requires plenty of sun, so ensure the location receives at least 6-8 hours of direct sunlight daily. The plant can be grown in containers, but it is essential to choose sufficiently large ones with drainage holes.
Watering Needs for Dolichos elatus Baker
Dolichos elatus Baker should be watered regularly depending on the prevailing weather conditions. During the hot and dry season, the plant needs frequent watering to maintain adequate moisture levels in the soil. It is essential to provide moderate watering to avoid waterlogging which may lead to root rot. Irrigation should be minimal during the rainy season, but the plant still requires moisture.
Fertilization of Dolichos elatus Baker
Before planting, mix the soil with compost to enhance soil fertility. Dolichos elatus Baker requires abundant amounts of nutrients, especially nitrogen and potassium. Fertilize the plant using organic matter such as compost, manure, or fish emulsion. Apply the organic fertilizer 2-3 weeks after planting and repeat every 4-6 weeks throughout the growing season.
Pruning of Dolichos elatus Baker
Pruning Dolichos elatus Baker is essential to reduce the height of the plant and promote bushier growth. Pruning involves removing the tip of the main stem when plants reach a height of 15-20 cm. Pinching the tips of the lateral branches that develop prevents the plant from becoming too woody and promotes the growth of a more extensive vine.
Propagation of Dolichos elatus Baker
Dolichos elatus Baker, commonly known as the "green shell bean," is a tropical perennial plant that is native to Southeast Asia. The plant is widely cultivated for its pods and seeds, which are used as a food source. Propagation of the plant can be done through several methods:
Seed Propagation
Seed propagation is the most common method of propagating Dolichos elatus Baker. The seeds are usually harvested from mature pods and dried in the sun before planting. The seeds can be directly sown in the field or in containers. To improve the germination rate, the seeds can be soaked in water for 24 hours before planting. It takes about 2-3 weeks for the seeds to germinate.
Cutting Propagation
Propagation through cuttings is also possible but less commonly used. Cuttings are taken from mature plants and planted in a suitable potting mix. The cuttings should be about 6 to 8 inches long and have at least one node. The cuttings should be watered regularly, and after a few weeks, new roots will develop from the nodes.
Division Propagation
Division propagation is another method of propagating Dolichos elatus Baker. This method involves dividing the plant into smaller sections and planting them in separate containers or directly in the field. The plant should be carefully dug up, and the clump should be divided into smaller sections with a sharp knife. Each section should have at least one healthy shoot and root system.
Overall, Dolichos elatus Baker is a relatively easy plant to propagate. Seed propagation is the most common and easiest method but, in some cases, a combination of these methods may be used to improve the yield and overall quality of the plant.
Disease and Pest Management for Dolichos elatus Baker
Dolichos elatus Baker, commonly known as the pink-fleshed bean, is a species of flowering plant that belongs to the legume family. To maintain the healthy growth and yield of this plant, it is crucial to deal with any diseases or pests that might affect the plant in a timely and effective manner. Here are some common diseases and pests that might affect Dolichos elatus Baker and their corresponding management methods:
Diseases
Bacterial Blight
This is a bacterial disease that affects the plant's leaves and pods, causing brown patches and water-soaked spots. To manage this disease, remove and destroy all affected plants and avoid planting in the same area for at least two years. Also, ensure to use clean seed and practice good crop rotation.
Anthracnose
This is a fungal disease that affects the plant's leaves, stems, and pods, causing sunken lesions that are usually dark in color. To manage this disease, remove and destroy all affected plants and avoid planting in the same area for at least two years. Also, ensure to use clean seed and practice good crop rotation. Fungicide sprays may also be necessary.
Pests
Aphids
Aphids are insects that suck the sap from the plant's leaves, causing wilting and stunted growth. To manage this pest, introduce natural predators such as ladybugs and lacewings, which feed on aphids. Alternatively, use insecticidal soap sprays or strong water sprays to dislodge the aphids.
Spider Mites
Spider mites are tiny insects that feed on the plant's fluids, causing discoloration and sometimes death. To manage this pest, avoid over-fertilizing the plant, as this may attract spider mites. Introduce natural predators such as ladybugs, lacewings, and predatory mites. Alternatively, use insecticidal soap sprays or neem oil.
Proper management of diseases and pests is crucial to keep Dolichos elatus Baker free from any harmful infestations and ensuring that it continues to grow and thrive. By following the suggestions given above, you can cultivate a healthy and productive crop of Dolichos elatus Baker.
