  This paper is based on the study of the paper of Scardigli and Casadio [Eur.
Phys. J. C (2015) 75:425] where the authors computed the light deflection and
perihelion precession for the Generalized Uncertainty Principle (GUP) modified
Schwarzschild metric. In the present work, we computed the gravitational tests
such as Shapiro time delay, gravitational redshift, and geodetic precession for
the GUP modified Schwarzschild metric. Using the results of Solar system
experiments and observations, we obtain upper bounds for the GUP parameter
$\beta$. Finally, we compare our bounds with other bounds in the literature.
