You asked about teak plantation in your land.Its a nice one ,good investment and 100% safe.If you plant localy availiable teak stumps it will grow in the good manner.But you have wait for minimum 25 to 30 years for harvesting.Ok the above said period is over ,what will happend during the harvest? You wnt get Rs 10000/- per tree minimum.An account of this pARAMETER YOUR TIME AND MONEY WILL WASTE.In this regard what i am suggesting you kindly go for Tissue culture Teak saplings .its a wise investment.The maximum cultivation period is 10 years.From the tissue culture plantation you will get assured income.The salient features of the tissue culture are uniform growth ,growth rate is 10 to 12 feet per year.The main cretaria is the setting of heart wood will be morethan 70% .By planting teak stump you will get less than 30% .So The heart wood portion is deciding factor fixing price of the timber.
