A delegation of Congress leaders from both the states as also some MPs from Rajasthan and UP have planned to meet Finance Minster P Chidambaram in this regard.
After the meeting with Gandhi, Bajwa said it was urgent for them to apprise the leadership of the "ill-effects" on farmers of the proposed amendment before it became a law.
Bajwa had said in Amritsar yesterday that Punjab Congress leaders have impressed on the party leadership not to go ahead with the imposition of the tax as it would affect a large number of farmers in Punjab and the response of the leadership was "positive" on the issue.
SAD and BJP have decided to hold statewide dharnas on the issue on May 2 in Punjab.
Meanwhile, Congress Vice President Rahul Gandhi had a separate meeting with party MPs from Arunachal Pradesh, Meghalaya and Manipur and discussed organisational matters.
