No University affiliated with my Diploma college but we need to fill the university name from where we've completed our Diploma while filling the form.

Dear Aditi

If no university is affiliated with the college from which you have pursued your Diplom course, then in that case, you can simply mention the name of your college itself in the registration form. However, if you still want some more clarification on the same, then you are advised to contact the Admission Help Desk of Krishna Institute of Engineering and Technology, where the admission counsellors will answer your query precisely as per their college requirements. The admission helpline number of the college is mentioned here for your convenience: 18001200106. 

Hope this helps you! For any further queries, please feel free to ask!
