Kulwisana na Nkayivelo wa Vitamin A
Mpfumaleko wa Vitamin A (VAD) ixiphiqo lexikulu xa rihanyu laha tikweni ra Afrika Dzonga. Kuya hi ndzavisiso lowu wahaku endliwaka wukomba leswaku 43.6% ya vana vamalembe ya 1-5 na 27% ya vavasati lavanga ringanela ku tswala vana vahluphiwa hi nkayivelo wa vitamina A VAD.Vitamin A yina nkoka eka ku vona hi matihlo yitlhela yipfuneta masocha ya miri ku lwela miri eka mavabyi. Nkayivelo wa vitamin A wuvangiwa hikuva vanhu vanga dyi ngopfu swakudya leswingana vitamin A.
Ku dya swakudya leswinga fuwa hi vitamin A tani hi matsavu yofana na mihlata y axitshopani i ndlela ya nkarhi woleha leyi hlohleteriwaka hiva Agricultural Research Council (ARC) kuhunguta nkayivelo lowu. Mihlata leyi ya xitshopani yitirhisiwa ngopfu nale ka mphakelo wa swakudya eswikolweni.
Nhlata wa Oranji Endzeni - Swakudya swo Fuwa Ximilani Olova Kuxibyala
Mihlata yinyika matimba, yitlhela yiva na swakudya swotala hiti vitamina C na B nati minerali to tanihi magnesium, zinc na iron leswi lavekaka emirini wa munhu. Yitlhela yinyika swakudya leswi fuweke hi vitamin A tanihi beta-carotene. Beta-carotene yotala yihlayiseka loko mihlata yivirisiwa leswitlhelaka swinyika mihlata nkarhi wakuva vitamin A yi antswisiwa, leswi swikumiwile hiva South African Medical Research Council. Swimilani leswi switirhisiwe hinhlayo leyikulu leswaku switakota ku lwisa nkayivelo wa vitamin A ematikweni yofana na Mozambique na Uganda laha vanga humelela swinene.Vaka ARC vakote ku endla swakudya swohambana hambanaha leswi nga na nantswo wa kahle hiyona mihlata leyi ya xitshopani, leswi vuyerisaka no oma kambe swiri na nhlayo leyikulu ya beta-carotene. Ximakiwa xa BOPHELO xina 7700 µg/100 g yo virisiwa (or 640 µg/100 g) retinol activity equivalents (RAE). A 100 g ya xiave xo virisiwa xa mihlanta leyi yaxitshopani yitisa swilaveko swa swakudya leswi lavekaka eka vanhu va malembe yohambana hambana.
Maendlelo yo Humelerisa
Ximilani lexi chavanaka na gwitsi naswona swina nhlohletelo eka nkarhi wobyala:Ndzhawu
Gwitsi rintsongo
Gwitsi rikulu
Laha kungariki na gwitsi
Mpfula ya xixika
Tinhweti to Byala
Exikarhi ka Oct kuya eka Dec
Exikarhi ka Nov kuya emasungulweni ya Dec
Aug kuya eka March
Nov kuya eka Dec
Vanwamapurasi vanga tirhisa tindlela ta vutlharhi ta mabyalelo kutiyisisa leswaku mihlata yikumeka nkarhi hinkwawo wa lembe hikuva vabyala nhweti yinwana na yinwana kusukela hi October kuya eka January leswaku ntshovelo wutava kona kusukela hi February kuya fikela August ya lembe leri landzelaka. Mihlata yivakona hikuva ku tsemiwa matshindi ya kwalomu ka 20-30 cm hiku leha, lawa ya byariwaka ehansi ka misava.
Mpfhuka lowu siyiwaka exikarhi ka mintila xingava 0,75 – 1 m na kwalomu ka 25 - 30cm exikarhi ka mintila. Ku byala e forweni swihlohleteriwa swinene leswaku swita vuyerisa swinene xikanwe no tiyisisa leswaku mihlata ayivaviseki hinkarhi wa ntshovelo.
Ntshovelo wa mihlata wu endliwa endzhaku ka 4½ wa tinhweti eka tindzhawu letihisakakuya eka 5 watinhweti eka tindzhawu letinga hiseku ngopfu endzhaku ko byala. Kuna swotala swinga endliwaka hi mihlata kufana ti chips, juice, doughnuts.
Ku kumeka ka Mbewu ya Swibyariwa
Kutsemeleriwa ka matshindi kusuka eka mihlata swi endliwa ngopfu hiva Sweet Potato Vine Growers Association (SPVGA) lava swi endlaka hi nhlayo leyikulu kumbe hi nhlayo leyintsongo. Vaka ARC hivona vanyikaka vanwamapurasi hi matshindi lawa yanga tsemeleriwa naswona yatlhela yakamberiwa loko yangari na mavabyi, notiyisisa leswaku ya byariwa hindlela leyifaneleke ngopfu ngopfu eka kusivela switsotswana na mavabyi.Vabyari va wona wa languteriwa kuva valandzelela milawu leyi fambisanaka na maendlelo lawa ya vekiweke. Masimu ya kamberiwa no tiyisisiwa hi vakamberi vaka ARC loko matshindi yanga se tsemiwa. Matshindi yantshwa ya nhlayo yalehenhla yosuka eka vaka ARC yanga kumeka kusuka hi August kuya fikela hi April.Translated by Ike Ngobeni
