Tosefta for Bikkurim 2:3
יֵשׁ בַּתְּרוּמָה וְבַמַּעֲשֵׂר מַה שֶּׁאֵין כֵּן בַּבִּכּוּרִים, שֶׁהַתְּרוּמָה וְהַמַּעֲשֵׂר אוֹסְרִין אֶת הַגֹּרֶן, וְיֵשׁ לָהֶם שִׁעוּר, וְנוֹהֲגִים בְּכָל הַפֵּרוֹת, בִּפְנֵי הַבַּיִת וְשֶׁלֹּא בִפְנֵי הַבַּיִת, וּבָאֲרִיסִין וּבֶחָכוֹרוֹת וּבַסִּקָּרִיקוֹן וּבַגַּזְלָן. הֲרֵי אֵלּוּ בַתְּרוּמָה וּבַמַּעֲשֵׂר, מַה שֶּׁאֵין כֵּן בַּבִּכּוּרִים:
<i>Terumah</i> and <i>Ma’aser</i> share [laws] that are lacking in Bikkurim: that <i>Terumah</i> and <i>Ma’aser</i>'s threshing-floor remains are prohibited, and they have a specified amount to be given, and they are taken from all [species of] produce, [and their laws apply] both in Temple times and in post-Temple times and they are applied to produce of sharecroppers, renters, <i>Sikrikonim</i> [those who forced another to give up land at the threat of death], and thieves. All of the above is for <i>Terumah</i> and <i>Ma’aser</i>, but not for <i>Bikkurim</i>.
