Propagation and Planting
Dragon fruit plants can easily multiply through stem cuttings. Generally, 20-25 cm long cuttings are used for planting. These should be prepared 1-2 days before planting, allowing the latex to dry. The cuttings should be taken from elite mother plants after the fruiting season and treated with fungicides to prevent diseases. How to plant dragon fruit involves placing cuttings in polyethylene bags filled with soil, farmyard manure, and sand in a 1:1:1 ratio. The bags should be kept in a shady place for rooting, avoiding excess moisture to prevent rotting.
The propagation of dragon fruit is relatively straightforward and can be done using stem cuttings or seeds. However, stem cuttings are preferred as they ensure true-to-type plants and faster fruiting.
To propagate dragon fruit from cuttings, select healthy, disease-free stems from a mature plant. Cut the stems into sections of 20-25 cm in length and allow them to dry for a day or two to prevent rot. Treat the cut ends with a fungicide to reduce the risk of fungal infections. Plant the cuttings in polyethylene bags filled with a mixture of soil, farmyard manure, and sand in a 1:1:1 ratio. Place the bags in a shaded area and water sparingly to encourage root development. Once the cuttings have been rooted, they can be transplanted to the field.
Training and Nutrient Management
Dragon fruit trees are fast-growing vines that require proper training. Planting is usually done at a 3×3 m distance, with poles to support the vines. Nutrient management is crucial, with the recommended dose of fertilizers varying with soil type and location. Organic manure and neem cake are often used, with additional fertilizers applied at various stages of growth to ensure optimal yields.
Dragon fruit plants require proper training and support structures to grow efficiently and produce high yields. The plants are usually trained on vertical poles or trellises to keep the vines off the ground and promote better air circulation and sunlight penetration.
Single-post systems are commonly used, where each plant is supported by a vertical pole of 1.5-2 meters in height. The vines are allowed to climb the poles and branch out at the top, forming an umbrella-like structure. This method helps in maintaining a manageable plant height and facilitates easy harvesting.
Nutrient management is essential for the healthy growth and productivity of dragon fruit plants. The plants have a superficial root system that can rapidly assimilate nutrients. The recommended dose of fertilizers varies depending on the soil type and location of the plantation. In general, 10-15 kg of farmyard manure (FYM) or organic manure and 100 g of single superphosphate (SSP) per plant are recommended at the time of planting.
For the first two years, apply 300 g of nitrogen (N), 200 g of phosphorus (P), and 200 g of potassium (K) per plant per year. For mature plants, increase the dosage to 540 g of N, 720 g of P, and 300 g of K, applied in four equal split doses at three-month intervals. The nutrients should be supplied at key stages: before flowering, at fruit set, during harvest, and after harvest.
Combining organic manure with neem cake and applying a balanced fertilizer (19:19:19) every three to four months helps in maintaining soil fertility and ensuring a steady supply of nutrients.
Pest and Disease Management
While generally tolerant to pests and diseases, dragon fruit trees can be affected by fungal and bacterial pathogens such as anthracnose, brown spots, and stem rots. Regular pruning and proper irrigation are essential to maintain healthy plants. Various control measures, including chemical treatments and good agronomic practices, can help manage these issues effectively.
Dragon fruit plants are relatively resistant to major pests and diseases, but they can still be affected by some common issues. Fungal diseases such as anthracnose, brown spots, and stem rots can occur, especially in areas with high humidity and rainfall. These diseases can cause significant damage to the plants if not managed properly.
To prevent and control fungal diseases, regular monitoring of the plants is essential. Remove and destroy any infected plant parts to prevent the spread of disease. Applying fungicides such as Saaf fungicide or mancozeb at 2 g/L can help prevent anthracnose, while carbendazim at 1 g/L is effective in controlling the disease once it has occurred. Rotting diseases can be managed by avoiding excess sunlight and using copper oxychloride at 0.2%.
Insect pests such as ants, scale insects, mealybugs, slugs, bores, caterpillars, termites, nematodes, fruit flies, bats, rats, and birds can also affect dragon fruit plants. These pests can be managed through a combination of agronomic practices, crop hygiene, and chemical Insecticides. Using copper sulfate, fruit, soil amendment, and sterilization can help control pest infestations.
Regular pruning of the plants to maintain an open and manageable canopy helps in reducing the incidence of pests and diseases. Proper irrigation practices, such as using drip irrigation, help in maintaining optimal soil moisture levels and reducing the risk of waterlogging, which can predispose the plants to diseases.
Harvesting
The dragon fruit harvest period in India is typically from June to October. The plants start yielding 12-15 months after planting, with fruits ready for harvest 25-35 days after flowering. Proper harvesting techniques involve selecting ripened fruits and handling them carefully to prevent damage. The fruits are then stored in suitable conditions to maintain freshness and extend shelf life.
