Hello Prash,
If you have no exp in farming till now, my advice would be to start doing it in a small piece of land nearby where you work (may be within one hour distance from where you stay now). No need to buy land now, try your best in a leased out land. See if you are getting adjusted to farming and whether you are getting sustained income from that leased out land. Atleast try and see if you can get vegetables for yourself without depending on outside market vegetables. Try your best to see how you can keep away the pests and what are different ways of keeping the pests away. How the land can be irrigated with less water, how to survive without chemical fertilisers etc etc…unless you do research your own with your plants and soil, you are not going to learn much and earn much consistently.
Try this for one or two years and see how it works for you. You are still @ 35. There is lot of time left even if you do some research for a year or two. There is no need to jump into farming by resigning your job and buying more land with whatever money you have. Try it out with leased land and if it works very well, go for it 100%. During this one or two years, search for a good land with plenty of water availability. By this time you will have farming friends locally who can help you in getting good fertile cheap lands.
Last but not the least, since you are single and if planning to move into a married life sooner or later, see that you select your better half who is 100% adjustable with your farming plan and has passion for it like you
