Climate Requirement for Custard Apple Cultivation:- Well, custard apple thrives better in tropical climatic conditions. Especially dry, hot and humid conditions favor its growth and fruit set. Moderate winter conditions and high humid conditions during flowering stage and fruit set can yield excellent fruit crop. These trees cannot withstand the frost and severe cold conditions. Areas susceptible to high winds and heavy rains can cause flower and fruit drop, and limb damage. The ideal annual rainfall for custard apple cultivation is about 500 mm to 800 mm.

Soil Requirement for Custard Apple Cultivation:- Custard apples can be grown in a wide variety of soils with good drainages such as fertile sandy, shallow, marginal lands, and wastelands. However, if the sub-soil is ill-drained, then you should avoid planting these trees. Best yields are possible in deep black soils with good draining conditions. Avoid soils which have high alkalinity, chlorine, poor- drainage. Soils which are prone to waterlogged conditions should be avoided. The ideal soil pH for Custard apple cultivation is 5.5 to 6.5.

Propagation and Seed Treatment in Custard Apple Cultivation:- Propagation can be done both by seeds and vegetative methods. Seeds extracted from quality fruits are used for sowing. Custard apple seeds usually last for 2 to 3 years with the best viability. Seed treatment should be carried out by soaking the seeds in cold water for 50 to 60 hours and treating with GA3 500ppm for better germination percentage. Apart from seed, Grafting and Budding are vegetative methods used for propagation of custard apple crop.

Land Preparation in Custard Apple Cultivation:- The land preparation is just like any other fruit crop. Make the field weed free by giving 2 or 3 ploughings along with a couple of harrowing. You can bring the soil to fine tilth stage with this preparation. You can make drainage channels as part of land preparation.

Seed Sowing, Planting and Spacing in Custard Apple Cultivation:- The planting method of triangular or square systems can be adapted in custard apple cultivation. You can directly sow the seeds in the main field or seedlings raised on nursery beds. Grafting planting method is ideal for quick plant growth than seed sowing. In case of seed sowing, the ideal temperature for germination is about 18°C to 26°C. Avoid direct sunlight until they have fully germinated. Seeds that grow in these conditions usually produce seedlings within 3 weeks. However, germinating these in colder climates may take up to 60 days.

Dig the pits with a size of 60 cm x 60 cm x 60 cm at a spacing 5 cm x 5 cm (plant-to-plant and row-to-row distance). However, these measurements may vary depending on soil, variety, and planting method. These pits should be ready before the rainy season. Fill these pits with topsoil and 25 kg of farmyard manure (like cow dung). Along with FMY, you can also apply single super phosphate and neem cake under dry conditions. Once rains started, you can plant saplings in the center of the pits. The basic requiems like staking, providing shade and watering should be done after planting in the field.

Intercultural Operations in Custard Apple Cultivation:

  • Care of Yong Plants: The gap filling should be done as early as possible. Replace dead or weak trees as part of gap filling with the same age of trees.
  • Weed Control and Intercropping: To keep the orchard clean, you should make the weed-free field by removing them regularly. You can give shallow cultivation between the rows and clean the tree basins. You can also earn some income by intercropping with some short period crops like legumes (green gram, black gram, red gram etc..), peas, beans, herbs, and marigold flowers.
  • Mulching: Mulching can be done at around the plant base for controlling the weeds and protecting the soil moisture. This can also prevent soil erosion. Mulching materials like paddy straw, coconut husk can be used. After some time, these mulch materials decompose and work as excellent organic manures. However, Now a day’s commercial growers using plastic mulch which you can get in the market.

Training and Pruning in Custard Apple Cultivation:- Training of the young plants is required to establish a strong framework especially during the initial stages of the growth period.
