'''Nyasi''' ni [[kundi]] la [[mimea]] inayofunika [[udongo]]; nyasi zilizo nyingi si kubwa sana lakini aina kama [[mwanzi|mianzi]] hufikia [[urefu]] wa [[mti|miti]]. [[Biolojia|Kibiolojia]] hujumlishwa katika [[Familia (biolojia)|familia]] ya [[Poaceae]] au [[Gramineae]].

Nyasi nyingi huwa na [[mzizi|mizizi]] mirefu inayoshika ganda la juu la ardhi hivyo kuzuia au kupunguza [[mmomonyoko]] wa udongo. [[Ekolojia|Kiekolojia]] aina za nyasi zimezoea [[mazingira]] tofauti kabisa kati ya kanda za [[joto]] hadi kanda za [[baridi]] sana. Wakati wa baridi au [[ukame]] [[jani|majani]] juu ya ardhi hukauka hata kupotea kabisa lakini mizizi ina uwezo wa kulala muda mrefu na kusubiri [[mvua]] au [[halijoto]] ya juu zaidi.

== Lishe ya wanyama ==
Watu wametumia nyasi kwa shughuli mbalimbali. Nyasi ni muhimu kama [[lishe]] ya wanyama kama [[ng'ombe]] au [[kondoo]]. [[Wanyamapori]]  wengi wanakula nyasi vilevile. [[Wakulima]] wanaweza kuteua aina za nyasi zinazofaa kama lishe ya [[mifugo]] na kuzipanda. Kumekuwa sababu mbalimbali toka kwa [[wanasayansi]] kuelezea kwa nini [[binadamu]] hali nyasi.<ref>"[https://www.livescience.com/32435-why-cant-humans-eat-grass.html Kwa nini binadamu hakuli nyasi?]</ref>

== Nafaka, viungo na dawa ==
Aina kadhaa za nyasi hutoa [[mbegu]] zinazoliwa na watu kama [[nafaka]]; nyasi hizo za nafaka kama vile [[mahindi]], [[mpunga]] au [[ngano]] ni kati ya vyakula vya msingi vya binadamu [[duniani]] kote. [[Asilimia]] 70 ya mimea yote inayopandwa ni nyasi.<ref name="Time life 19">{{cite book|title=Grasslands and Tundra|publisher=Time Life Books|year=1985|series=Planet Earth|editor=George Constable|isbn=0-8094-4520-4|page=19}}</ref>. Aina nyingine za nyasi hutumika pia kama [[dawa]] za aina mbalimbali kwa binadamu na viungo vya chakula au [[vinywaji]] kama [[chai]].

== Mimea kwa burudani ==
Katika mazingira ya mjini nyasi za pekee hutumiwa kufunika ardhi hasa katika maeneo ya [[bustani]] yanayokanyagwa na watu wengi wanapenda kukalia kwenye nyasi na kupumzika; aina hizi zinatumiwa pia kwenye viwanja vya [[michezo]]. Katika bustani nyasi hukatwa kwa mitambo maalum kuwa fupi ili kupendezesha bustani, tofauti na nyasi za mashambani au sehemu za kulishia wanyama.<ref>"[https://www.coppafeelgarden.com/zero-turn-mower/ mitambo ya kukata majani]</ref> Nyasi hutumika pia kufunika ardhi nje ya [[nyumba]] ili kuipendezesha.

== Ujenzi ==
Nyasi hutumika pia kwa [[ujenzi]] wa nyumba, mara nyingi maeneo ya vijijini, hasa katika [[nchi zinazoendelea]].
