Hello sir,
it is very difficult to answer this question with provided information,
weather,soil,crops, season,nearness to the market,duration of crops and investments these are the factors which are going to influence the returns.
there are crops with minimum investment of Rs.2000-10000 (coriander) earn Rs.25000 to 50000 when cultivated at specific season and by cultivating sandal wood you can earn 1 crore/ac in 15 years. protected cultivation(requires investment of 10 lakh) also high investment oriented, so do think of those factors which suits you and your investment capacity, try to have integrated farming system
do farming,rare dairy, fishery,sheep/piggery/poultry etc and select the crops and venture and ask specific queries
