Hello Sushmanjali,
Actually, it depends on your interest because it's a Masters degree program which is professional and it requires research to complete the degree. So you need to have a good base on the subject plus your interest.
But if you really want a specific subject, I would suggest you go for Agronomy and soil science are evergreen subject, but nowadays soil science is a better option due to more vacancy in the public sector.
For private sector entomology, pathology & plant breeding & genetics are a better option. If u have good memorizing capacity then you can choose entomology. From my point of view, soil science and plant breeding are the best options nowadays.
Hope this helps.
