Ku Cinca Cinca Swimilani: Ku cinca cinca swimilani swina nkoka swinene eka kusivela mavabyi naku tala kumbe kuhangalaka ka switsotswana. Mihlata ayifanelanga ku byariwa kuhundza kanwe eka malembe yanharhu hiku landzelelana eka misava yin’we.
Swimilani leswinga fanela kuva swibyariwa hileswi kotaka kuvuyelerisa misava kufana na tinyawa, khavichi na mavele ngopfu ngopfu eka misava leyi hatlisaka kuva yihelela hiswakudya.
Matsemelo Na Mabyalelo Ya Tshindi: Maendlelo lawa i yaku tsema tshindi. Tshindi rakona rifanele kuva kwalomu ka 20-30 cm hiku leha. Matluka yafanele kususiwa eka tshindi loko ringa se ya byariwa nakambe, kambe sweswo aswina nkoka. Kutsema hile henhla swinga onha swinene eka swirho swinwana swa swimila leswi. Nkarhi wunwana kutsemiwa swinga endliwa kusuka eka timintsu letinga khoma swakudya. Ku byariwa ka timintsu swinga endliwa hikuva tifunengetiwa himisava. Loko seswimirile no leha kwalomu ka 25-30 cm, tinga tshoviwa kumbe kutsemiwa titlhela tiya tirhisiwa kumbe kubyariwa nakambe.

Unga tsema 20-30 cm wa tshindi leri hanyeke kahle, leri pfumalaka switsotswana na mavabyi leswinga endliwaka hi mukwana wokarhiha swinene. Ya byali eka misava leyi lulamisiweke hikuva u saletela hi misava yotsakama kukondza yasala ntsena hafu ya wona. Tshikelela laha matlhelo ka wona kutiyisisa leswaku misava yitiyerile no tiyisa tshindi leswingata endla leswaku ya hatlisa ya mila timintsu. Cheleta swibyariwa hi mati loko u heta ku byala. Tiyisisa leswaku u tsema tshindi leri hanyeke kahle himinkarhi hinkwayo. Unga tirhisi matshindi yosuka eka swimilani leswingalo timilela hiswoxe hikuva swingava na switsotswana na mavabyi.
Kululamisa Misava: Misava yilava ku ceriwa kumbe kurimiwa kahle hiku tirhisa xikomu, foroko kumbe xipedi. Yilava kurimiwa ku kondza yifika eka 250-300 mm leswaku timintsu tita kota kunghenelela xikanwe no nava kahle ehansi. Susa maribye kumbe kufayelela maguvadi hiku tirhisa hariki hambi xikomu kukondza misava yilulamela kubyala. Manyoro yanga cheriwa emisaveni kwalomu ka 3-4 wa tinhweti loko kungase byariwa swimila swihi kumbe swihi.

Mabyalelo: 1. Mugerho: swimilani leswi swabyaleka emigerhweni. Mugerho wupfuna laha tindzhawu takona tingavaka na makhukhula naswona wu endla leswaku swiolova ku tshovela. Tshindi ribyariwa eka 30cm kuya eka rinwana e ribuweni ra mugerho. Laha kunga vekeriwa tshindi kufanele kutshikeleriwa leswaku rita tiya swinene. Tshindi ribyariwa riyimele henhla laha 3-4 wa marhengu ya nghenaka ehansi ka misava leswaku yata humesa timintsu.
2. Flatbed: va nwamapurasi vanwana valulamisa ndzhawu leyi vange i flatbed leswaku vata kota kubyala eka yona eka misava leyingana sandi leswaku vata kuma mbuyelo wa kahle swinene.
Mavekelelo: Nhlata wutekiwa tani hi xibyariwa xale masinwini kungari ekaya tani hi matsavu. Leswi swiendliwa hileswi swimilani leswi swikotaka kunava naswona switeka ndzhawu yikulu swinene.
Exirhapeni xale kaya (laha ndzhawu yinga yintsongo) ntila wunwe kumbe yimbirhi yingava yilulamile. Vekela tshindi riva exikarhi ka 25 – 35 exikarhi (mpimo wa xipedi) eka ntila wun’we. Hixitalo mugerho na ribuwa ra yona rifanele kuva na mpimo woringana 1m hiuk hambana. Swinga koteka kuva yiva kwalomu ka 90-150 cm hiku hambana kumbe 80-90 cm exirhapeni xale kaya, naswona kungava 30-40 cm hiku leha.

Nkarhi Wo Byala: Eka tindzhawu letingariki na gwitsi rikulu: Emasunguleni ya November kuya exikarhi ka December. Eka tindzhawu leti gwitsi swinene: Exikarhi ka November kuya emasunguleni ya December. Kasi eka tindzhawu leti kupfumalaka gwitsi: Kusuka hi August kuya eka March. Eka tindzhawu leti tinga hola, kusuka hi September kuya eka February. Eka tindzhawu letingana mpfula hi xixika: Exikarhi ka November kuya emasunguleni ya December; November yiva nkarhi wa kahle.
Kunonisa Misava: Swikombiso swa misava swifanele kutekiwa tinhweti loko kungase byariwa leswaku kuta ololoxiwa swiphiqo leswi khumbhaka kunona ka misava. Manyoro yo hambana hambana yanga tirhisiwa kuya hi muxaka wa misava. Ammonium sulphate yikota kuhunguta pH ya misava kasi LAN yikota ku engetelela pH ya misava.
General recommendations: Nhlata wu hanya ngopfu hi nitrogen na potassium leswivulaka leswaku ratio ya N na K yifanele kuva e henhla swinene. Kwalomu ka 1000 kg/ha (100g/m2) ya nkatsakanyo wa manyoro tani hi 2:3:4 (30) yanga tlhela ya hangalasiwa kungase byariwa naswona yafanele ku tirhiwa swinene loko kunga se endliwa foro yo byalela eka wona. Eka misava leyingana sandi, nhlayo yinga kurisiwa kuya fika eka 1200 kg/ha. Ku cheriwa 120-150 kg/ha LAN (12 g per meter of row) or 200 kg/ha (20g/m2) ammonium sulphate kwalomu ka 3 wa mavhiki endzhaku kaloko kubyariwile loko swirina nkoka. Misava leyingana sandi yilava kucheriwa manyoro kambirhi. Yitlhela yicheletiwa kahle endzhaku ko chela manyoro. Muxaka wunwana wa manyoro wunga tirhisiwa ku ngetelela lawa yanga cheriwa. Kambe manyoro yakona yafanele kuva ya vupfile swinene (6 wa tinhweti). Kumbe yakatsiwa na misava kwalomu ka tinhweti kunga se byariwa. 15-20 m3 (4 big hands/m2) yanga haxiwa no katsiwa na misava loko kunga se byariwa nchumu.
Ku Cheleta: Nhlata wutala ku hanya kahle na laha kungana dyandza. Leswivulaka leswaku ximilani lexi xikota ku humesa mihandzu ya kahle hambi loko ku omile laha kunga byariwa kona. Ku kala ka mati swingova na xiave eka mihandzu leyi humaka. Kupfumaleka ka mati eka mavhiki yosungula yobyariwa na nkarhiwova timintsu tikula kahle (30-60 wa masiku endzhaku ko byala) swita endla leswaku ntshovelo wuva wuntsongo. Kuya hintolovelo, mihlata yilava kwalomu ka 450 na 600 mm ya mati yocheleta kusukela loko yaha ku byariwa.
Ku Tshovela: Mihlata yiva yiringanele kutshoveriwa endzhaku ka 4 wa tinhweti (eka tindzhawu letihisaka) kuya eka 5 watinhweti lomu ku kufumelaka kusukela kubyariwile. Misava yifanele kuva leyi olovaka hinkarhi wantshovelo leswaku mihlata yinga tshoveki no vaviseka. Yifanele kucheletiwa kuringana 30 wamasiku loko kungase tshoveriwa tani hindlela yolulamisela ntshovelo. Eka tindzhawu leti hisaka matshindi yafanele kutsemiwa eka 4-7 wamasiku kunga se tshoveriwa.
Ku fanele kutirhisiwa foroko ku fukula mihlata ehansi ka misava se ku hetisisiwa hi voko kutsuvula mihlata. Unga tirhisi xikomu kumbe xipedi ku cela. Tiyisisa leswaku unga celi mihlata hi yoxe. Mihlata yinga tshoveriwa xikanwe hinkarhi wunwe. Loko nguva yo leha yivakona, mihlata yita kula ngopfu. Dzudza misava eka mihlata, uyi hlantswa, uyitshika edyambyini kuringana 1-2 wati awara loko maxelo ya hisa swinene. Eka 32°C mihlata leyinga tshoveriwa yinga hatla yi vuna hikokwalaho ka kuhisa ka dyambu endzhaku ka 30 watiminete. Loko yitshikiwa emasinwini vusiku hinkwabyo laha maxelo yavaka ehansi ka 5°C, mihlata yinga vaviseka swinene. Mihlata yilava kuvekiwa eka ndzhawu leyinga oma no hola (15°C).
Ku Hlayisa: Mihlata yingaha hlayisiwa laha yivaka yahari kahle kuringana 3-6 wa mavhiki endzhaku ka ntshovelo. Unga hlayisi mihlata leyivavisekeke. Swakoteka kuva u tshika mihlata yitshama kwale masinwini kufikela nkarhi lowu munhu alavaka kuyi tshovela. Swikahle kuva u engetelela nguva yotshovela hikuva u siya nkarhi wa mavhiki eka kubyala mihlata laha u siyaka mavhiki yambirhi exikarhi.
Tsundzuka: Unga cheleti eka nkarhi lowu. Eka tindzhawu leti kutitimelaka mihlata yihatla yivaviseka yiri emisaveni. Kasi loko maxelo yaha pfumela, mihlata yita kota kuya emahlweni yikula.
Hlayiselo rinwani ra mihlata roka ringa durhi ikuva yi celeriwa eka goji roka ringa entangi emisaveni. Laha unga tlhelaka u vekela mabyasi yo oma laha henhla. Paka mihlata yiva eka 40-45 cm hiku enta. Se uvekela byasi na misava leswinga oma ehenhla kayona. Pfala hi byasi byo oma lebyi ungata byi endla lwangu. Mihlata leyi yinga tshama kuringana 4 wa tinhweti. Ma endlelo lawa yanga endliwi hi xixika eka tindzhawu letingana timpfula.
Switirhisiwa: Mihlata yinga tirhisiwa hiti ndlela tohambana hambana:
Mihlata yinga dyiwa yinga swekiwangi, yi virisiwile, yi bakiwile, kumbe yiswekiwile
Le makumu ka mihlata na matluka swinga dyiwa tani hi matsavu
Matshindi yakona yanga nyikiwa swiharhi swidya
Mihlata yinga tirhisiwa ku endla xinkwa, swo baka hiswona, machipisi, jamu na juzi
