The party's legislators disrupted proceedings in the question hour, forcing Speaker Pranab Gogoi to adjourn the house for 10 minutes.
Soon after the proceedings restarted, 18 AIUDF legislators pressed for an adjournment motion, which the speaker refused to allow.
Pandemonium prevailed for more than an hour as the AIUDF members alleged that illegal arms were in the hands of Bodo rebels and these should have been confiscated after the clashes in lower Assam which claimed more than 100 lives since July.
As the speaker refused to admit the adjournment motion, the AIUDF legislators staged a walkout and later announced they would boycott the next four days of the session.
Party leaders, however, later told reporters that a final decision on the proposed boycott of the assembly session would be taken at a meeting.
On behalf of the government, forest minister Rockybul Hussain said that the house was prepared for a discussion but the matter should be brought before it in accordance with the rules.
