There exists a major difference of opinion between two Acharonim, Joseph Karo and Moses ben Joseph di Trani, as to whether produce grown on land in Israel which is owned by non-Jews also has sanctity. According to Karo, such produce has no sanctity and may be used and/or discarded in the same way as any produce grown outside of Israel. According to di Trani, the fact that this produce was grown in Israel, even by non-Jews, gives it sanctity, and it must be treated in the special ways detailed above.
