Use the official lists on the institute page for those.The main agriculture degree in India. It covers crop science, soil, plant protection, animal husbandry, extension and farm economics, and it ends with a period of village and field work.
The same shape as the agriculture degree but built around fruit, vegetables, flowers and plantation crops, including nursery work, post harvest handling and processing.
Veterinary science and animal husbandry. It is a professional degree with a compulsory internship, and it is what qualifies somebody to treat animals.
Machinery, irrigation, soil and water conservation, farm structures and processing. Closer to an engineering degree than to an agriculture one.

Specialisation in agronomy, soil science, plant pathology, entomology, horticulture, extension or agricultural economics. Research funded posts usually need this or more.
Weeks rather than years. Beekeeping, mushroom growing, nursery raising, dairy management, soil testing and drone operation are all taught at Krishi Vigyan Kendras and state institutes, often free.
What each degree teaches, semester by semester, is on the syllabus page. The exams that lead into these are on the exams page.
