Dear Sri tkkumar,
One basic advise is that, the farmer should monitor the high density mango crop very closely. Abcent farmers may not get much success results.
M/s Jain Drip Irrigation company did a high density mango plantation garden in Udumulpet, Tamilnadu ( near Coimbattore ) @ 1,333 plants and 666 plants in around 5 acres each, @ spacing of 1mtr x 3 mtrs and 2 mtrs x 3 mtrs . Visited twice in 2008-09 and 2010-11. Doing it in a successful way. Variety - Alphanso.
It is diffarent when comparing with traditional plantation.
In high density plantation:
Income is more.
risk is more.
Investment is more.
yield waiting period is less.
Close observation required.
Naturally High density plantation gives more profit and of course, with lot of risks
It is not latest technology. It is being in practice from more than a decade. So many farmers of Maharashtra, Telangana,Andhra Pradesh and Karnataka are in practice and are successful and it is a proven technology.
Up to my knowledge most of the farmers went for high density in Alphonso,Bangenapalli, Amrapali and such new hybrids and never came across Thotapuri ( bengalura ) mango. One fact is that this variety mango plant grows very fast and heavily. Mostly in High Density plantation slow/less growing varieties are preferred ( like Amrapali, Alphonso etc )
with best wishes, g.p.rao, farmer
