  We improve our previous QCD sum rule calculation on G(KN\Lambda) and
G(KN\Sigma) coupling constants by including the contributions from higher
dimensional condensates, <\bar{q} g_s \sigma \cdot G q> and <\bar{q}q>
<(\alpha_s /\pi) G^2>, in the OPE. It is found that the contribution of these
condensates is non-negligible compared to that of the quark condensates. Using
a best-fit analysis we find |G(KN\Lambda)| = 2.49 $\pm$ 1.25 and |G(KN\Sigma)|
= 0.395 $\pm$ 0.377.
