The southern state's farmers protesting for the past 21 days have received support from various other outfits and political parties.
The farmers are demanding loan waiver, drought-relief package of Rs 40,000 crore and setting up of Cauvery Management Board from the Centre.
Rajewal said difference in language is not an issue as farmers across the country are facing similar problems. He said his outfit plans to hold such protests across the country after the harvest season.
Tamil students studying at Jawaharlal Nehru University in the national capital are also expected to join the farmers tomorrow.
