  We report the results for nucleon decay searches via modes favored by
supersymmetric grand unified models in Super-Kamiokande. Using 1489 days of
full Super-Kamiokande-I data, we searched for $p \to \bar{\nu} K^+$, $n \to
\bar{\nu} K^0$, $p \to \mu^+ K^0$ and $p \to e^+ K^0$ modes. We found no
evidence for nucleon decay in any of these modes. We set lower limits of
partial nucleon lifetime 2.3$\times10^{33}$, 1.3$\times10^{32}$,
1.3$\times10^{33}$ and 1.0$\times10^{33}$ years at 90% confidence level for $p
\to \bar{\nu} K^+$, $n \to \bar{\nu} K^0$, $p \to \mu^+ K^0$ and $p \to e^+
K^0$ modes, respectively. These results give a strong constraint on
supersymmetric grand unification models.
