Poyankha chodabwitsa ichi, mapangidwe a njira yoyeretsera paddy amafuna kuyeretsa njira zambiri ndikuchotsa miyala, ndikulimbitsa kupeta kuti zitsimikizire kuti paddy woyeretsedwayo ndi wabwino. Sizingangodalira chosankha chamtundu kuti chisankhidwe pagawo lomalizidwa. Posankha zida zoyenera zoyeretsera, tinthu tating'onoting'ono tosiyanasiyana timasanjidwa panthawi yoyeretsa, kenako nkumasiyanitsidwa ndi zipolopolo ndi kuyeretsa, kuchepetsa mpunga wosweka ndikuwongolera mtengo wamtengo womalizidwa.
Kuonjezera apo, ngati mpunga wa bulauni pambuyo pa de-husking wabwezeretsedwa ku chowotcha kuti ugubuduze, n'zosavuta kuthyoledwa.
