Apart from Mr Zeliang of the Naga People's Front, prominent among those who filed their nominations Wednesday included former chief minister K L Chishi of the BJP.
Because of the last-hour rush, compiling the final list party-wise is taking time, Chief Electoral Officer Abhijit Sinha told reporters.
A scrutiny of nomination papers would be held on Thursday and the last date for withdrawal is February 12.
Though filing of nominations for the election to the 60-member House had started on January 31, the first batch of 22 contestants filed their nominations only Tuesday.
Political parties in the north-eastern state had stayed away from nomination filing till yesterday, as the Core Committee of Nagaland Tribal Hohos and Civil Organisations (CCNTHCO) had, through a joint declaration on January 29, appealed to them to refrain from participating in the election.
The CCNTHCO had sought the support of the political parties to its call for a solution to the protracted Naga political issue first.
