Crops for low maintenance, quick production and high returns

Looking for advice from experienced farmers. Our farm is near Mysore, Karnataka.
What are those crops that are low in maintenance, gives yields quickly and are sold at high amount? We will be using drip irrigation, fertigation systems and any latest technologies to get good yields.


You can use Hydroponics technique to grow.
Fast and high yields would be of micro greens and herbs.

Thanks for the response. Do you have some info on the sale price of microgreens, who buys them, cost of production, initial investment etc.,?
Are for growing microgreens Hydroponically?
