Observation variables consist of pest attack rate, crops height and production. The results showed that the mulching treatment have a significant effect of attack intensity of S.exigua on onion crop, but has no effect on crop height and production. Onion crops that grown without using a mulch have a high rate attack from pest than the onion without mulching. Key Words : Onion, mulch, Spodoptera exigua.
