Cultivation of Sapota achras P. Mill.
Sapota achras P. Mill. is a tropical evergreen fruit tree that thrives in warm and humid climates. It requires full sunlight exposure to grow, so planting it in an open field is the best option. The tree can grow up to 20 meters tall, so it needs enough space to spread out. It can be propagated by seeds or grafting.
Watering Needs of Sapota achras P. Mill.
Watering is crucial during the initial stages of growth in young sapota plants. Adequate irrigation must be provided, ensuring the soil is moist but not waterlogged. Young plants require frequent watering up to three times a week until they are fully established. After that, the tree can survive on rainfall alone, but it would benefit from occasional watering during dry spells.
Fertilization of Sapota achras P. Mill.
Sapota achras P. Mill. responds well to organic fertilization. Farmyard manure, compost, and green manure can be used to enrich the soil before planting. During the growing season, it is advisable to add nitrogen-phosphorus-potassium (NPK) fertilizer to enhance growth. An application of 10-10-10 NPK fertilizer every six months would suffice. However, over-fertilization may cause excessive vegetative growth, leading to poor fruiting.
Pruning Sapota achras P. Mill.
Sapota achras P. Mill. requires minimal pruning. Still, it is essential to prune dead or diseased branches to prevent the spread of diseases. During the initial stages of growth, pruning can be done to shape the tree structure. However, excessive pruning may stunt the tree's growth and affect the fruit yield. It is advisable to seek professional advice before pruning mature trees.
Sapota achras P. Mill.: Propagation Techniques
Sapota achras P. Mill., commonly known as sapodilla or chikoo, is a tropical evergreen tree that belongs to the family Sapotaceae. It is a highly valued fruit tree that is propagated by several methods, including seeds, grafting, and air layering.
Propagation by Seeds
Sapodilla can be propagated by seeds, which are taken from ripe fruits. Seeds must be sown in a well-drained potting mix that is kept moist but not waterlogged. Germination takes up to 30 days and can be improved by soaking the seeds in water for 12 hours before planting. Plants propagated by seeds take longer to fruit and may exhibit undesirable characteristics.
Propagation by Grafting
Grafting is the most common method of propagating sapodilla. It involves joining a scion, which is a piece of twig with buds from a desired cultivar, to a rootstock, which is a seedling grown from a different sapodilla variety. Grafting can ensure that the resulting plant bears fruit of the desired quality and quantity. It is typically done during the rainy season, and the grafted plants are kept in a shaded area until they are established.
Propagation by Air Layering
Air layering is another method of propagating sapodilla that involves the creation of a small wound on a mature stem to stimulate root growth. The stem is then covered with soil or another rooting medium and held in place with a plastic sheet or aluminum foil. Once roots have developed, the stem is cut from the tree and planted in a pot or a desired location. This method is suitable for trees that are difficult to graft and can produce fruit earlier than seed-grown trees.
Disease and Pest Management for Sapota achras P. Mill.
Sapota achras P. Mill., also known as chikoo or sapodilla, is a popular fruit tree that is grown in many parts of the world for its sweet and delicious fruit. However, like all plants, chikoo is susceptible to various diseases and pests that can harm the plant and reduce fruit production. Here are some common diseases and pests that affect chikoo and ways to manage them.
Common Diseases
Fruit rot: Fruit rot is one of the most common diseases that affects chikoo. It is caused by fungi, and the symptoms include small water-soaked spots on the fruit that eventually turn brown and spread. To manage fruit rot, it is important to remove all infected fruits and affected plant parts and spray the plant with a fungicide. Also, maintain proper soil moisture and avoid overhead watering to prevent the growth of fungi.
Anthracnose: This secondary infection affects the sapodilla fruit in both green and mature stages. The indications of this disease are irregularly formed dark or brown raised spots on the fruit's skin, which may extend to harm the flesh. 1% Bordeaux mixture or Dithane Z-78 (0.2%) is used to treat and control the infection. Spraying has to be completed when the fruit is young and regularly repeated.
Leaf spot: Leaf spot is characterized by small to moderately-sized circular or oblong lesions, which may manifest primarily to the lower foliage but may progress to the upper leaves in severe cases, leading to defoliation. Defoliation results in poor photosynthesis, the weakening of the tree, and crop reduction. Treatment includes clearing the infected leaves and spraying a copper-based fungicide on the tree's canopy and trunk.
Common Pests
Fruit flies: The nematodes that are produced by fruit fly larvae are highly damaging to chikoo trees. During the warmer months of the year, these pests lay their eggs in the sapodilla's immature fruit. Young trees may be struck by a strong attack. Farmers can employ netting and insecticides that inhibit insect growth to prevent these pests from laying eggs near fruit.
Mealybugs: Mealybugs are tiny whitish soft-bodied bugs that reside on the plant's leaves and stems. They feed on the sap which is being taken from the plant, resulting in weak growth and reduced fruit production. To get rid of mealybugs, thorough pruning should be done to remove affected plant parts, followed by spraying the tree with a mixture of soap and water or using specific insecticides.
Spider mites: Spider mites prefer hot and arid weather, causing plant yellowing and stunted foliage growth. To manage spider mites, it is essential to spray the tree's foliage with a miticide that can control and eliminate them. Neem oil or insecticidal soap solutions may be used to decrease their population.
It's critical to pay close attention to your chikoo tree and recognize the symptoms of any illnesses or infestations. Identifying symptoms early can aid in disease or pest management and treatment, improving the sapodilla tree's yield and health.
