Hello Ritik,

If you are referring to Jawaharlal Nehru University, then then the answer is NO, it does not provide a B.Sc. Agriculture course

But if your query was regarding the B.Sc. Agriculture at Jaipur National University then YES, the admission is through JNU-CET exam.

To be eligible for the same you must have cleared 10+2 exam or an equivalent exam. 

B.Sc. Agriculture Honours at Jaipur National University is a 4 year long course with a few of ₹70,000p.a.
