so you are interested in doing course related to agriculture ,both agricultural engineering and bsc in agricultural are different course. BSC in agricultural is a under graduate course which of 3 years in which you study about the fundamental principles of agricultural on the other hand agricultural engineering or B.tech is a under graduate professional degree which is of 4 years and in this you study about the engineering principles of agricultural.

you may choose any one of them or may go for any other course of this stream .
