Ilayisi liwuhlamvu olunjengokolweni, ibhali, ummbila, nokunye okuningi. Ziyizinhlamvu zezinhlobo ezithile zezitshalo. Ekuqaleni kwakuwutshani obumnandi. Kusukela ngeNkathi Yamatshe, abantu bebelokhu begcina okusanhlamvu okukhulu kunawo wonke kuze kube yintwasahlobo elandelayo futhi baphinde bayisebenzisele ukuhlwanyela. Kwavela kanjalo okusanhlamvu kwanamuhla, kuhlanganise nelayisi.
Izitshalo zerayisi ezincane kufanele zimbiwe futhi zitshalwe kabusha ngesikhathi esisodwa futhi kuhlukaniswe izikhala eziningi. Isitshalo serayisi sibe sesiba cishe ingxenye yemitha noma imitha elilodwa nengxenye ukuphakama. Phezulu kukhona i-panicle, i-inflorescence. Ngemva kokuvundiswa ngumoya, izinhlamvu ziyakhula. Noma yisiphi isitshalo serayisi singazivundisa ngokwaso.
Imivubukulo ithole ukuthi irayisi yayisivele ilinywa cishe eminyakeni eyi-10,000 edlule: eChina. Lesi sitshalo cishe safika entshonalanga ngePheresiya, i-Iran yasendulo. AmaRoma asendulo ayazi irayisi njengomuthi. Kamuva, abantu baletha nelayisi eMelika nase-Australia.
Cishe ingxenye yabo bonke abantu, irayisi liwukudla okubaluleke kakhulu. Yingakho kubizwa nangokuthi ukudla okuyisisekelo. Abantu okusebenza kubo lokhu bahlala ikakhulukazi e-Asia. Irayisi eliningi liyatshalwa nase-Afrika. Ngakolunye uhlangothi, emazweni aseNtshonalanga, abantu badla kakhulu ukudla okwenziwe ngokolweni. Nakuba ummbila uvame ukutshalwa kunelayisi, ngokuvamile uphakelwa izilwane.
