Mishnah 1א׳
בְּאֶחָד בַּאֲדָר מַשְׁמִיעִין עַל הַשְּׁקָלִים וְעַל הַכִּלְאַיִם. בַּחֲמִשָּׁה עָשָׂר בּוֹ קוֹרִין אֶת הַמְּגִלָּה בַּכְּרַכִּין, וּמְתַקְּנִין אֶת הַדְּרָכִים וְאֶת הָרְחוֹבוֹת וְאֶת מִקְוְאוֹת הַמַּיִם, וְעוֹשִׂין כָּל צָרְכֵי הָרַבִּים, וּמְצַיְּנִין אֶת הַקְּבָרוֹת, וְיוֹצְאִין אַף עַל הַכִּלְאָיִם:
On the first of the month of Adar a proclamation is made about the [giving of the] shekalim and about kilayim [forbidden mixed plantings]. On the 15th of the month the Book of Esther is read in cities. Additionally, they repair the roads between cities, the roads within cities, the mikvaot [pools for ritual immersion], take care of all public needs, mark graves and remove the kilayim [from the fields].
Mishnah 2ב׳
אָמַר רַבִּי יְהוּדָה, בָּרִאשׁוֹנָה הָיוּ עוֹקְרִין וּמַשְׁלִיכִין לִפְנֵיהֶם. מִשֶּׁרַבּוּ עוֹבְרֵי עֲבֵרָה, הָיוּ עוֹקְרִין וּמַשְׁלִיכִין עַל הַדְּרָכִים, הִתְקִינוּ שֶׁיְּהוּ מַפְקִירִין כָּל הַשָּׂדֶה כֻּלָּהּ:
Rabbi Yehuda said: At first they used to uproot [kilayim] and would throw it away before them. When sinners began to multiply [i.e. when people did not remove the kilayim] they would uproot it and throw it on the roads. [Eventually,] they decreed that the entire field should be declared ownerless [and anyone can take food from these fields - because the owners did not remove their kilayim at all].
