Dear Sri Viswa, Agriculture income is uncertain and depends on time of harvest , rate prevailing on that time, agents character and so many other factors.
As regards income of grapes, Dilkush and Anabsahi, seeded grape varieties yields will be twice an year in and around Bengaluru rural, Kolar, Chikballapur districts and one yield will be around 20 to 35 tonnes and other will be around 5 to 10 tonnes, ie; a total of 30 to 40 tonnes per year.
Market rates will be around Rs 5, 10,20 …even up to rs 60/- per kg.
In the above said areas, seedless grapes gives almost 10 to 12 tonnes and prices will be in the range of rs 20/- to rs 80/-.
The profitsin the hands of farmers will be after so many natural and/or middle men hurdles.
with best wishes, g.p.rao, farmer
