Hello,
I have 5 acres of land with limited water supply in Tirupur region, TamilNadu. Considering Tamarind as a pension crop, planning to cultivate Tamarind(sweet variety). But many are discouraging me saying that it is labour intensive and not so easy to market the produce. So just want to know the economic feasibility of Tamarind cultivation.
25 trees acomodate one acer at the spacing 42x42 or 13x13m
The time for a tamarind tree to reach its first harvest will vary, depending on the method of propagation.
A tree propagated by bud-grafting will come into bearing in 3 to 4 years, whereas trees propagated by
seed may take up to 12 years. Practical management and local conditions will also affect the time for
trees to bear. A well tended tree, grown from seed, in an open area will come into bearing in about 7
years. Regardless of the method of propagation, pod yield should stabilise after 15 years. The tree has
a pod bearing capacity of 50-60 years, but may yield fruit for over 200 years.
Fruit ripeness and yield
Pod skin colour does not change rapidly with maturity and individual fruits mature at different times, so
harvesting should be carried out selectively. Mature fruits should have a brown shell, while immature
pods have a green skin. At maturity, the fruits are filled with a sticky brown to reddish-brown pulp and
the seeds become hard and glossy. The pod skin becomes brittle as the pulp shrinks and the shell can
be broken easily by hand. The ripe pod produces a hollow sound when tapped with the finger.
The yield of a tamarind tree varies considerably and is dependent on genetic
and environmental factors. Pod yield can also be cyclic, with bumper yields in every third year. A
young tree may yield 20-30kg of fruit per tree in a year and a full-grown adult tree can yield about
150-200kg of fruit per tree in a year. An average tamarind tree may yield 100kg of fruit per tree in a
year. Pod yield can decline after 50 years. Once the pod yield is no longer profitable, the tree may be
harvested for charcoal or fuelwood. if you want any more details feel free to contact
