Hi
My one cent contribution for the people who are new to this coconut cultivation:
I do own a coconut form and i am happy to share my experience.
1. There are three variations in coconut variety at the broader level and they are:
1. West coast tall. -- takes 6 - 7 years to start yeilding. In this there are many sub - varities in this. For example - In Karnataka, the famous one is Tiptur variety. In Tamilnadu, the high yeild one is Pollachi variety (This one requires moister in air to give better yield).
2. short variety - gives yeild in 4 years and have a lifespace of 20 - 30 years.
3. Hybrid and cross varieties - Start yield at 3 years. Yield is 30 - 40 % than the regular varities. However, you need to take care very well.
If one is looking to setup a coconut farm with more than 100 seedlings, I strongly suggest you to visit the farm directly and see the parent trees before buying the seedlings. Particularly for the Hybrid item, it is very very important. The seller selling the coconut seedling should have a certified coconut parent tree and a unit who is well trained in creating cross. Otherwise, it is not at all advisable.
Also, there is one another growing market is tender coconut market. This would give you lot of scope if your farm is near a city.
Another important thing is, you need to have water for next 25 years. If you are doubt about this, i would go for Tamarind cultivation. The Tamarind requires relatively very less water and less care. The hybrid Tamarind is expected to generate more revenue than coconut (!).
I am more happy to share my experience. please send me private message if needed.
With wishes,
Siva.
