Hi akshaya, Saveetha Engineering College and  Amrita Vishwa Vidyapeetham both are deemed to be universities. Both the colleges offer agricultural courses. Amritha university offers B.Sc Agriculture {Hons.} - 4 years and Saveetha college offers B.E Agriculture Engineering - 4years. Both of the agri courses are not ICAR affiliated (not approved by ICAR). I suggest you better visit their college websites to know more. Additionally you can call and contact the college admission officer and ask your inquires. Hope it helps. All the best.
