Hello dear student !

BHU is one of the renowned universities in India. In order to be eligible for MSc. in agriculture in BHU, you need to qualify a 4 year bsc. In agriculture degree or equivalent degree such as horticulture. So if you have done BSc. in Botany , you are NOT eligible for MSc. in agriculture in BHU. Meanwhile, you can apply for other MSc. Courses in BHU such as MSc. in Botany.

Hope this helps!
