We determine the effective cone of the Quot scheme parametrizing all rankr, degreedquotient sheaves of the trivial bundle of ranknon. More specifically, we explicitly construct two effective divisors which span the effective cone, and we also express their classes in the Picard group in terms of a known basis.
