Valedictory function saw the convention condemning the murders of rationalist Dr Narendra Dabholkar, CPM leader Govind Pansare and Kannada writer M M Kalburgi.
A resolution passed during the function said the central and the state governments should ensure "fearless and promising atmosphere" so that freedom of speech is not attacked.
President of this year's convention Dr Sripal Sabnis sought immediate measures to stop farmer suicides in Maharashtra.
The convention demanded that the state government send a proposal to Central government seeking 'classical language' status for Marathi. Education Minister Vinod Tawde said the state government was committed to perusing this demand.
Sabnis, in his closing address, said the border issue with Karnataka should be settled out of the court. "There is a BJP-led government in the state (Maharashtra) and at the Centre. The government can declare the disputed area as a union territory," he said.
