  In noncommutative space, we examine the problem of a noninteracting and
harmonically trapped Bose-Einstein condensate, and derive a simple analytic
expression for the effect of spatial noncommutativity on energy spectrum of the
condensate. It indicates that the ground-state energy incorporating the spatial
noncommutativity is reduced to a lower level, which depends upon the
noncommutativity parameter $\theta$. The appeared gap between the
noncommutative space and commutative one for the ground-state level of the
condensate should be a signal of spatial noncommutativity.
