The effect of rubber rolls in husking machine (Yanmar type) on rice cultivars of Tarm Hashemi (TH) and Daillman Mazandarani (DM) were tested during husking at three clearances of 0.4, 0.6 and 0.8 mm between cylinders. The experiments were carried out in a factorial experiment under complete randomized design with three replications. The results showed that the TH cultivar was significantly better than the DM in all studied conditions. The results showed broken rice of 6.239 % and 6.729 %, cracked grain percentage of 3.787 % and 4.671 %, brown rice (husked rice) of 82.049 % and 80.113 %, husking efficiency of 84.719 % and 83.152 % and head rice yield of 70.633 % and 69.202 % for TH and DM, respectively. The clearance of 0.8 mm was significantly superior to the levels of 0.4 and 0.6 mm in all studied conditions.
