SOIL & CLIMATE

Vetiver prefers warm humid tropical and subtropical climate with an annual rainfall of 1000 2000 mm, up to an altitude of 1300 m, in a temperature range of 21oC to 44oC.

It is mainly cultivated as a rainfed crop in hill slopes.
Plant requires plenty of sunlight and long day condition.
Vetiver grows on almost all types of soils but a rich and well drained sandy loam is the best. It grows in saline and sodic soils, sandy soils, riverine soils, marshy areas and tolerates high degree of water logging and moisture stress.


Roots from crops grown in light soils yield very low percentage of oil whereas roots obtained from red lateritic soils with abundant organic matter are thick and contain more essential oil. 
Heavy soils make harvesting of roots difficult, with a loss of finer roots which contain most of oil.

Distribution and habitat: Vetiver is indigenous to India, Pakistan, Bangladesh, Sri Lanka and Malaysia.

Haiti and Indonesia account for 80 % of total vetiver oil production in world.

In India, it is seen growing wild throughout Punjab, Uttar Pradesh and Assam.  Though, it grows well on hillsides, natural habitat is low, damp sites such as swamps and bogs.

It is cultivated in states of Rajasthan, Uttar Pradesh, Karnataka, Tamil Nadu, Kerala and Andhra Pradesh.  
Uttar Pradesh produces the highest quantity of oil, mainly from wild plants.
Vetiver oil produced from North India is the best and costliest in world.
