To add your article from the Journal of Krishi Vigyan on ResearchGate, first log in to your account. Click on “Add new” and choose “Add publication.” Then select the type of publication (like “Article”) and fill in the details such as the title, journal name, authors, and year. You can also upload a PDF if allowed. If the paper is already on ResearchGate, you can search for it and click “Claim this publication” to add it to your profile.
If you want to create a profile for the journal itself, you can’t make a separate journal account, but you can create a “Project” on your profile named Journal of Krishi Vigyan. In that, you can add information about the journal, upload files, and invite collaborators.
Dear Manoj Sharma Apparently your journal is not listed in the RG database. See for more info https://help.researchgate.net/hc/en-us/articles/14293139566353-Journals
1. Journals in RG's database for using in bibliographic data of papers. As Rob Keller explained, there is no possibility to add journals to this database manually. In case of a missing journal in RG's database, I add the bibliographic data to the abstract field (like, e.g., in https://www.researchgate.net/publication/344474227 and https://www.researchgate.net/publication/268925009).
2. Profiles of journals (example: https://www.researchgate.net/journal/International-Perspectives-in-Psychology-2157-3891). See https://help.researchgate.net/hc/en-us/articles/24012471222545-Journals-on-ResearchGate for more information. I guess the publishers have to pay for these profiles.
What do you mean by creating a "Project"? Unfortunately, RG abolished the projects about two years ago and deleted them. See, e.g., https://www.researchgate.net/post/Were_retiring_Projects_on_March_31_2023/1.
