Students willing to apply for MBA in Agri-Business are required to get the minimum eligibility criteria of  an aggregate score of 50% at the graduation exam from a recognized institute of higher education. They must have completed their graduation with agriculture or allied farming as primary subject. Now you haven't specified the college you have applied to but I am guessing if the college has around 70 seats then you have a very good chance of getting in. The more seats the merrier for you. If the seats are less than 50 then you might hope to get in the second or third round of counselling.
