Dushyant Chautala's Jannayak Janta Party is also contesting the elections.
Some 1,169 candidates are in the fray for the 90 seats in the Haryana Assembly elections scheduled for October 21.
The main contest is between the Congress and the Bharatiya Janata Party (BJP), which has set a target of winning 75 seats for itself riding on the hype of the abrogation of Article 370 and the National Citizens Register (NRC).
The Congress is focusing on issues like the economic slowdown, rising unemployment and farmers distress in its campaign. While Congress leader Rahul Gandhi has so far addressed a rally in Nuh. Another one is scheduled to be addressed by the party's interim chief Sonia Gandhi on Friday.
The Chautala clan-led Indian National Lok Dal (INLD) as well as its offshoot Dushyant Chautala's Jannayak Janta Party (JJP) are also trying to make a dent in the votes of the two parties. Some seats are likely to have a triangular contest.
While the BJP and the Congress are contesting on all 90 seats, the BSP is in fray on 87 seats, and the INLD is contesting on 81 seats. There are some 375 candidates contesting as Independents.
