Hello there. Hope you are doing good. In general, the admission criteria for B.Tech Agriculture is that you should have Physics, Chemistry, Maths/Biology in your 10+2 and should have minimum 50% aggregate but it varies. Since you have not mentioned the specific college you are looking for. I will not be able to help you with the cutoffs as they vary from one college to another. You can mention the college name so that I can help you better. Good luck for your future.
