Chii chakaitwa

Mufananidzo uyu unoratidza kuti kurimwa kwachinja sei. Pamberi pa1990, mbatatisi dzaive chikafu chikuru; mbesa dzakakohwewa dzaichengetwa sembeu pasi pemibhedha kwemwedzi mipfumbamwe munguva yekupisa kwemvura, zvipembenene nezvirwere zvaisatarisirwa zvakanaka, uye goho raisvika paavhareji ye10 t/ha. Nekuwedzera kwekubudirira uye huwandu hwembatatisi dzetafura kubva kumapurovhinzi ari pedyo eChina, mbatatisi dzakava chirimwa chemari chekugadzirisa pasi pezvibvumirano nePepsiCo Vietnam neOrion Foods Vina.
