Crop Management

Shading

Necessary to provide 1st 2 yrs of growth and thereafter shading and mulching during dry spells to avoid leaf scorch.

Irrigation weed control

During 1st 5 yrs in droughts only during 1st 5 yrs of growth.

Fertilizer

N:P2OJ:K2O 12:14:14 mixture as recommended by DOA.

Insect pest

Scales

Leaf eaters

Gamboge disorder

Secretion of yellow colour latex on to the edible portion of the fruit known as gamboge disorder is one of the major draw backs in mangosteen. Such fruits become inedible with bitter taste. Some times latex exudates onto the fruit surface, affecting the appearance and marketability.

Causes for the disorder is not certain. Nutritional imbalance and sudden changes of moisture content may be the reasons.


Harvesting & Post-harvest Technology
Fruiting Commences 8-10 yrs- Seedling -No. of fruits/year500-1500/tree (30-50 yrs old)
4 - 5 yrs Graft - 15 - 30 fruits/tree/yr- 15 yrs old

Fruiting seasons
LCWZ - May -July
MCWZ - July - September

Harvesting
When 25% fruit find turns pinkish, purple and with the stalk should be plucked at the point where it is attached to the fruit. Ground harvesting should be avoided as fruits get hardened.
