Hello Sara, 

You won't get admission for agriculture through NEET exam, because NEET does not include Agriculture course. 

To get admission in agriculture, you need to go through various other exams like 

ICAR, BHU, and state agriculture exams, also there are many other colleges that conduct their sperate exam for agriculture. 

To get admission in government and few private colleges and universities of agriculture in all over India you need to appear for ICAR.
