Tosefta Maasrot
A tree that part of it is planted in the Land [of Israel] and part of it is planted outside of the Land, since part of it is planted inside the Land, it is [treated] as though all of is planted in the Land, the words of Rebbi. Rabban Shimon ben Gamaliel says, the side (הצד not חצר, see Yer. Orlah I.1.17) planted in the Land of Israel -- behold, it[s produce] is [treated] like [produce grown in] the Land of Israel; and the side planted outside the Land -- behold, it[s produce] is [treated] like [produce grown] outside of the Land.
