Sorry you cannot get into agricultural engineering through jee main.

Taminadu takes separate entrance exams for admission.

Hello Savitha. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I have to say that Agricultural Engineering is a course that not many people have heard of as it is not a popular course. Great guts for you if you choose this discipline of study.

I would like to direct your attention to this link for more information about the colleges that offer this B. E or B. Tech course in Agricultural Engineering:

• https://collegedunia.com/btech/agricultural-engineering/tamil-nadu-colleges

I don't think any college in that link accepts admissions through JEE Mains. Sorry. 

Hope this helps you and all the best!
