We report on a search for the pair production of scalar
leptoquarks, LQ, using 191 pb^-1 of proton-antiproton collision data
recorded by the CDF experiment during Run II of the Tevatron. The
leptoquarks are sought via their decay into a neutrino and quark yielding
missing transverse energy and several jets of large transverse energy. No
evidence for leptoquark production is observed, and limits are set on
sigma(pp-bar -> LQ overline{LQ}X -> nu nu-bar qq-bar X). Using a
next-to-leading order theoretical prediction of the cross section for scalar
leptoquark production, we exclude first-generation leptoquarks in the mass
interval 78 to 117 GeV/c^2 at the 95% confidence level for BR(LQ -> nu q) =
100%.
