Hello, i am here to help you as per your query.According to me After qualified NET and cleared the selection process of a institution, then you can register for PhD program. The very first two years you are called junior research fellow (JRF).

A person with the fellowship registered under a research supervisor and activates the fellowship. JRF is upgraded to SRF (senior), directly in projects and via a presentation to a committee in case of exam qualified JRFs. The stipend for JRF is 25,000+ HRA and for SRF 28,000+HRA.

Hope,this information will helpful to you.
