Mangosteen

1 Comment

Mangosteen (Garcinia  mangostana Linn of the family Gutiiferae) is one of the most delicious and best  flavored fruits in the world. It is one tropical fruit that is most ready  accepted by the Western. It is a seasonal fruit that has a great export  market.

Growing Mangosteen for Business agribusiness The  editable portion of the mangosteen fruit is 1/3 of the whole fruit. The aril is  about 25-30% of the fruit and contains 19.8% soluble solids, 4.3% reducing  sugar, and 17.5% to total sugar. Analysis of the rind indicates that it is rich  in pectin.

Uses

The pulp, which is very light and soft and has an exquisite  flavor, is best eaten fresh, preferably after chilling the fruit. The pulp and  seed, when boiled with sugar, make an excellent preserve or topping for ice  cream or sherbet. The seeds have a delicious nutty flavor.

The leaves and bark, claimed to be medicinal, are used as astringent to cure aphtha or thrush. They  are also used as a febrifuge or antipyretic while the pericarp is regarded as  very effective in curing chronic intestinal catarrh.

The pericarp contains 7-15% tannin and it is used for dyeing. A decoction of  the root may be taken to achieve regular menstruation. Leaf infusion is applied  to wounds and a decoction of the pericarp may be administered to cure dysentery  or simply used as a lotion. Dried rind is used as an astringent. The seed  contains about 30% of valuable oil.

Mangosteen as Herbal Medicine

Recent studies shows that the rind (skin) has anti-oxidant, anti-bacterial, anti-fungal and anti-tumor properties. Initial results also reveals that mangosteen have anti-histamine and anti-inflammatory medicinal properties. The active therapeutic compound found in mangosteen is called “Xanthones”.

Xanthones provides many times more anti-oxidants than Vitamin C & E. Xanthones have been receiving much attention lately from researchers and scientist for its medicinal value. It appears to benefit every organ of the body. The whole mangosteen fruit is the single, best source of Xanthones.

The strong anti-oxidant properties of the mangosteen fruit fights free radicals in the body. This helps strengthen the immune system, promote joint and cartilage function, helps support a strong respiratory system and helps maintain good health.

Mangosteen is said to cure diarrhea.

  • Boil the required amount of seeds in two glasses of water for  15 minutes, or until only 1/2 of the liquid is left.
  • Cool and strain.
  • Divide the  decoction into four plants.
  • Drink one part every 2 to 3 hours.
  • Pack in  sterilized bottles.
  • Adult 4 tsp 7-12 yrs. old 2 tsp 2-6 yrs. old 1 tsp
  • Children  7-12 years, use half of the adult dose.

Favorable Growing Conditions

Mangosteen thrives best in warm, humid environment. Ideal temperature is  20°C-30°C. A temperature of less than 20°C slows down growth. Ideally, rainfall  should be well distributed throughout the year, but trees are known to grow  successfully even under dry conditions with irrigation. The soil should be rich,  porous, deep and wet but well drained. Heavy clay with a generous admixture of  sand and silt, and a water table of about two meters are best. It also grows  well up to an elevation of zero to 500 meters. The tree also thrives well along  river banks, canals, ponds and lakes. It grows best in areas with a well  distributed rainfall.

Seed System

Seeds are sown in seed boxes, seed flats or pots, bamboo tubes or plastic bags, under a cover. In a week or two, the seeds  sprout and the seedlings are to be kept in a nursery under partial shade and  watered 3 to 4 times a week. Usually, the seedlings take about two years to  become large enough for transplanting to a permanent field. At this stage, the  plants are about 30 cm tall.

Land Preparation

Before planting, condition the land and make it fit for the reception of the  trees. In clearing, all tree stumps should be removed along with as many roots  as possible. If a mangosteen orchard is to be established, land preparation  follows the system for other fruit crops. This consists of deep plowing once and  twice, followed by several harrowings, until the desired soil tilth is attained.  Stakes are set at a distance of 8-10m corresponding to the recommended distance  of planting for mangosteen. Holes are then dug at the positions occupied by the  stakes where mangosteen seedlings are set and covered with soil.

Crop Establishment

Planting system and distance of planting

Mangosteen seedlings are ready to be transplanted to the field when they are  two years old, at which age, they are about 25-30 cm tall. The seedlings are to  be carefully removed from the containers and set in the holes to avoid  disturbing the root system. The most suitable period to transplant is just after  the rainy season has set in. Planting in an area where there are light shimmers  is very helpful in ensuring satisfactory establishment of the young plants.

On level land, the trees are planted using the square system:spacing of at  least 8m x 8m between rows and between trees in a row. Some 156 seedlings to a  hectare are needed. The size of the holes should be 0.6m x 0.6m x 0.6m and filed  with farm manure. Plants are then set out at the center of the hole. Gradually  fill-in the hole with loose top soil. Gently press the soil until it firmly  grips the plant.

Weeding and Cultivation

Ring-weeding at one meter radius and loosening the earth are practiced to  preserve the fertility of the soil, as well as to allow the development of the  plants. Areas between rows are plowed for better weed control and cultivation.

Intercropping and Cover Cropping

Planting intercrops and cover crops in the mangosteen orchard is more or  less confined to the early years because, as the trees develop in size and  status, not much unshaded space is left in between rows for their proper  growth.

Mangosteen, in Sulu Archipelago, is usually planted with intercrops or  peanut and other leguminous field crops, or with companion plants like abaca and  banana, or marang and lansones trees. Other crops that may be intercroped also  are “dapdap” or durian trees which can serve as partial shades.

Nutrient Management

Mangosteen trees respond well to manuring. Diluted organic fertilizer which  can be absorbed slowly is desirable.

Also, application of a nitrogenous  fertilizer can accelerate vegetative growth of the plants.

Fertilizer application varies with the age of the plant. Since ammonium  sulfate is applied at planting time, succeeding application should follow a  circular outline following the tree’s canopy. Dig 4 to 6 holes following the  circular plan on the ground. Put the fertilizer into the holes, cover to prevent  volatillization, and to reduce runoff in case of heavy rains.

At planting time, apply 200-250 grams complete fertilizer per tree three  inches below the roots and five inches at the side of the seeding. For young  trees, mix and apply in two equal dosages 300-500 grams 14-14-14 or 12-24-12 and  broadcast or apply, by digging a shallow furrow around each tree, 200-300 grams  urea (45-0-0). Apply the first dosage at the start of the rainy season and the  second dosage at the end of the rainy season.

During the fruit-bearing stage, mix then apply in two equal doses 1.5 to 3.0  kg 14-14-14 or 12-24-12 plus 200-300 grams Muriate of Potash (0-0-60). Apply in  same manner as that for young trees.

Gradually increase the amount of fertilizer every year as the trees grow  bigger and as fruit production increases.

Water Management

Artificial irrigation is practiced during dry months. Water the plants as  soon as they are transplanted and sustain during the times when precipitation is  not adequate in order to keep the soil moisture at a high level.

In the seedling stage, however, standing water over the roots can kill the  plant outright.

Pest Management

Mangosteen is subject to several pests, the most common of which are mites,  aphids, fructifier ants and mealy bugs. Others, such as tussock caterpillars  feed on the leaves while coconut scales form colonies underneath the leaves  which causes leaf yellowing in patches thus impairing plant growth.

Occasionally, sooty molds are found covering the leaves. Diseases due to  anthracnose and bacterial leaf sheath have also been reported. As a preventive  measure, the plants may be sprayed two four time a year with common fungicides  at dosages recommended. Read the label before application.

Harvest Management

Mangosteen usually flowers in 10 to 15 years but if given proper care,  asexually propagated trees bear fruit in eight to nine years. It takes about  five to six months from flowering stage to fruit ripening.

Harvesting is normally done from the month of August to October. The fruit is  mature when its color changes from greenish brown to reddish purple and when it  is rather soft to the touch.

Great care must be practiced when harvesting fruits. Be sure that the fruits  are mature at harvest time, otherwise, they may fail to develop an excellent  flavor.

Handle the fruits with great care while harvesting. Handpicking is a good  method since the pericarp, which is still slightly soft at harvest is easily  subjected to injury when the fruits fall. As an alternative method use a long  pole with a hook at the tip and a catching basket attached at the end where the  fruits will be collected.

The method of harvesting employed in Sulu is hand picking the fruit with its  preduncle intact. Fruits are then bound together in elongated clusters of 15  pieces.
