Hi dear,
I would rather suggest you move to Hyderabad from Guntur. Agriculture University in Hyderabad should be a better place to start one's career.
Thanks.
All the best.

There are less chances for you.

Yes, of course, you can go for B.Tech in agriculture after 10+2 with Physics, Chemistry, Biology and/or Mathematics as subjects. Combination of subjects may vary depending on the university.

No, it's not mandatory. You can apply for M.Sc in forestry. As M.Sc. Is a good option. As Masters degree can give you good career opportunities. You can go through this.
Good luck.
