Starting the final day on 168 for five, Karnataka were effectively 9 for five at resumption of play.
They could add only 48 runs to their total as they were all out for 216 in 92.4 overs -- only 16 runs better than their first innings effort.
Save opener Kaunian Abbas (74) and Manish Pandey (58), none of the others could make a mark.
Veteram off-spinner Kamlesh Makvana (3/56) and slow left-arm bowler Jay Chauhan (4/71) were the wreckers-in-chief.
