Polling for the 70 Assembly seats will be held on February 8 and the counting of votes has been scheduled on February 11.
Chief Election Commissioner Sunil Arora also said that Das will reach Jharkhand on Saturday to take up his new responsibility.
With CM Raghubar Das being a non-tribal, the BJP will need to pull up socks to win in the 26 per cent tribal electorate base.
Sunil Arora also said former Indian Revenue Service (IRS) officers Madhu Mahajan and P Murli Kumar will be appointed as special observers in Maharashtra.
Arora said the poll panel had on February 26 this year again instructed that all political parties should take measures to not use single-use plastic.
Arora, who succeeds Lon Mincu Radulescu, the incumbent chairman from Romania, has been given the charge for two years from 2019 to 2021.
