The allocation for top agriculture college  cut-off was closed around 1000-1200 rank in 1st round. So, you have a  chance to get a seat for B.Sc. agriculture in 1st round. If you don't get any good college, You can try in further rounds. You will definitely get  seat in agriculture.

The allocation of seats depends on cutoff and it depends on various factors like

• The difficulty level of the exam
• Marking scheme
• Number of candidates appeared
• Number of available seats
• Seat reservation of various categories
• Previous year cutoff ranks/marks

Hope this helps!!

All the best!!
