Pls do not take a hasty decision. While the imagination of staying in the farm in the nature lures one to take it up as the full time job, the practical difficulties of growing the crops, marketing etc are really the other face of this life.
Agriculture requires patience and self experience. All the best practices that can get easily adopted in other industries do not work here.Even the expertise of the agriculture graduates and scientists do not help us much in this field. One need to test out the crops suitable to the soil & climate, test out the market for the crop, establish the market slowly and then take up agriculture as profession. If you do not have other means of income till you establish in the agriculture, then it is difficult.
While you continue to work in the prefession that you are in, try commercial crops in small scale, see through the compelte cycle from growing to marketing for atleast two years and then resign from job to take up agriculture as full time job.
I am doing the same..I have been trying the comemrcial crops in my farm for last three years. Now I have started to grow the selected crops in large scale. in another one year, when I can taste the success of the first large scale production, I am planning to resign from my existing Job..All the best to you
