Really depend what you have in mind with "project management".

If it really means "Microsoft Project without paying license", maybe GanttProject[1] is what you need.

If you want something that helps you and your team to manage your project from requirements to delivery and maintenance, you can have a look at Tuleap[2] (I'm part of dev team).

You can do the project management still of your own (waterfall, scrum, kanban, hybrid). If you are doing software development, it comes with git, gerrit, subversion native. It's a full featured ALM so it provides everything you need (documentation management, wiki, forums, IM, test mgmt, ...) without having to maintain N stack of incompatible tools with incompatible plugins & all.
