Farming ideas in Bangarapalem, Andhra Pradesh

I am planning to construct an orphanage near Chittoor, Andhra Pradesh, for which
I am planning to buy about 2 acres of agriculture land.
Since I need only .5 acre for the orphanage, I would like to use the remaining 1.5 acres
to grow vegetables/fruits that would provide some income to the orphanage.

The water source would be borewell, since there’s no other source of water avaialble.
Any ideas?
