Durian (Durio zibethinus Murr.) is a seasonal tropical fruit planted in Southeast Asia. It is one of the most expensive fruits in the region. To grow, Durian trees required rich, deep, well-drained sandy loam or loamy loam (alluvial or deep loamy soil), with a high organic matter content and a pH range of 6 to 7. Heavy clay soils, since they do not drain well, they do not tolerate the good growth and health of durian trees. When potted in light, sandy soil rather than rich clay material, the seedlings generate more vigorous growth. The land is prepared for sowing by first clearing and removing stumps, then plowing and harrowing twice. If it is too acidic for the soil, it can be remedied by adding agricultural lime. But staggered sowing will do without plowing and harrowing, and only the immediate outskirts of the hills will be cultivated. The root system of the durian tree is also sensitive to standing water, and it is important to have drainage, which in such inclined situations can take care of the roots. Say no to plagiarism.

One of the superior properties of durian generative propagation is seedling. The first step is to use fully grown seeds of the recommended varieties of ripe/ripe durian fruits. Seeds were soaked with fungicides or 1% Clorox solution before sowing and then washed. The purpose of immersion is to avoid fungal attacks. After that, the seeds are ready for sowing. Sowing seeds can be done in a plastic bag measuring 20cm x 25cm. Mix manure and soil in the plastic bag with a ratio of 1: 1. a plastic bag planted by a seed in an inclined position and not too deep. Within 3-5 days of planting, a successful seed can germinate, allowing seedlings to grow until pieces of the seed fall off. When the seed cotyledon has dissolved, fertilize using NPK (15:15:15) at a dose of 2 grams/litre of water using a sprinkler. For vegetative propagation, grafting. First, make a multiple stem of durian seedlings with approach patterns made by cutting the shoots from the additional stem (rootstock), one cotyledon was cut to 15cm high, then to the two opposite sides both sides the tip of the stem it was cut to create a wedge with two symmetrical parts. For each of the rootstocks with a blade from bottom to top until a slit was formed, the scion stem was cut. A part of the wedge under the additional rootstock was inserted into the scion slot. All sections of the rootstock and scion were aligned and fitted together, such that the sections of the two rootstock plants and the two sections of the scion were close to each other. A 1cm wide sheet of plastic was used to bundle the rootstocks and scion together, which was secured in place with grafting plastic. The growth and development of durian trees depends on the conditions of the planting medium. Create a sowing hole measuring 80x 80 x 70 cm or 70x 70 x 60 cm, or adapted to the type and conditions of the soil, and separate the soil from the subsoil (20 cm deep), or adapted to the type and conditions of the soil , and separate the soil from the subsoil (20 cm deep). The distance between the holes at least 8 x 8 m. Leave the planting hole for 2-3 weeks so that the poisonous soil gas expands thanks to the sun and comes.
