פירוש על קידושין 73:8

The first possibility is that R. Elazar is stricter than the first opinion. The first opinion says that the prohibition of eating new grain is prohibited only in Israel. The word “settlements” implies that Israel has taken possession and settled the land. Thus the prohibition is only applicable in a place that Israel takes possession of and settles—the Land of Israel. It is unlike orlah and kilayim which are obligatory everywhere.
