B.Tech

Just go with this link:
https://www.shiksha.com/engineering/food-technology-chp.

After completion of B.Tech, you can pursue M.Tech in Agriculture which includes study like crop process engineering, firm machinery and power, soil, water conservation, etc. A Ph.D. degree of three years is also offered at IIT Kharagpur, Indian Agricultural Research Institute (IARI), New Delhi.

You won't get seat in JNTUH with 28000 rank as it is very high and it doesn't meet the eligibility criteria. So try for another college. All the best.

If you want to do MBA/PGDM, Agribusiness Management is the course for you. IIMA offers Food and Agri-business Management.
I am a Food tech graduate, and I have no regrets of doing PGDM from MANAGE in ABM.
