Ngemva kokwenza izivivinyo zokwelapha ukuthuthukisa ukuziphatha kwesitshalo samazambane eCreole ngaphansi kwezimo zokushoda kwamanzi, uphenyo olwenziwa yiNational University of Colombia lwathola ukuthi i-calcium chloride ne-nitrate ingathuthukisa ukukhiqizwa kwayo.
Ngokocwaningo, ngokwemibandela ekhiqizayo, izitshalo ezazingenakho lokhu kwelashwa noma isithasiselo se-calcium zehlise isivuno sazo ngo-55.3%, kanti ezitshalweni ezikwenzile lokho, lokho kuncipha kwaba ngu-3% kuya ku-5 kuphela%.
Lokhu okungenhla kwembulwe isazi sezolimo namahlathi u-Wendy Tatiana Cárdenas Pira, Ingcweti Yesayensi Yezolimo yase-National University of Colombia-Unal Bogotá, okwathi, ngokucabangela ezinye izindlela zokwelapha ezinganciphisa isomiso ezitshalweni zamazambane, wafuna ukuhlola ukuthi ukusetshenziswa kokwelashwa kwe-calcium kungayinciphisa yini le nkinga yokucindezeleka ngenxa yokuntuleka kwamanzi.
"Inhloso bekuwukubheka engxenyeni yezobuchwepheshe nesayensi, ukusetshenziswa kokwelashwa ukuze, lapho isimo sibhekene nesomiso, sikwazi ukusinciphisa ngendlela elula," kusho isazi sezolimo namahlathi esiphinde sacacisa ukuthi lezi zindlela zokwelapha zahlolwa ekuqaleni. i-tuberization (lapho kwakhiwa khona i-tuber), okungesinye sezigaba ezisengozini kakhulu yesitshalo.
Lolu cwaningo lubalulekile njengoba kubonakale ukuthi abalimi abaningi bamazambane basezindaweni ezivame ukuba nesomiso futhi ngaphezu kwalokho, lokhu kuba kubi kakhulu ngoba isimo sezulu esibi siyabikwa esihlanganisa ukwenzeka kwezimo ezifana ne-El Niño. Ngakolunye uhlangothi, abalimi abaningi abanalo uhlelo lokunisela, okusho ukuthi, ekukhuleni kwabo, babhekana nesikhathi sesomiso esizonciphisa ukukhiqiza.
Kuyaphawuleka ukuthi lolu cwaningo, oluqondiswe nguSolwazi Liz Patricia Moreno Fonseca futhi ludidiyelwe nguSolwazi Luis Ernesto Rodríguez Molano, bobabili abavela e-Unal Sede Bogotá, basebenze namazambane ezinhlobonhlobo zeCriolla Colombia, okuyilona elilinywa kakhulu abalimi ngenxa yezimpawu zalo zokusebenza futhi ngenxa yokuthi, ngokwezinye izimo, ukuntula kwamanzi kuyancipha.
Njengoba kuqokonyiswe yi-Unal News Agency, ucwaningo lwaqala kulokho okutholwe ezincwadini futhi kwasetshenziswa izindlela zokwelashwa eziyi-10 ukuze kubonakale ukuthi kungaba yini ukusabela kwezambane elingaphansi kwesimo sokushoda kwamanzi: ezi-5 zahlolwa nge-application edaphic (eqondiswe phansi) kanye ne-5 nge-foliar application (emaqabungeni).
Kwabe sekwenziwa ukuhlolwa kokuphila komzimba: izitshalo zaba ngaphansi kokushoda kwamanzi ekuqaleni kwesikhathi sokufakwa kwe-tuberization kanye nokuguquguquka kokuziphatha komzimba kwesitshalo kwathathwa. Izinga lamanzi elilinganiselwe lakalwa ngokukhethekile, okuguquguqukayo okuvame ukuhlotshaniswa nesimo samanzi sezitshalo.
Ngaphezu kwalokho, amapharamitha acatshangelwa ikakhulukazi ekucutshungulweni kwezimboni anqunywa: indaba eyomile, amandla adonsela phansi athile kanye nesivuno samazambane ngokwenani lezilimo eziyizigaxa ngesitshalo ngasinye namagremu e-tuber ngesitshalo ngasinye. Konke lokhu kwenziwa ngaphansi kwezimo ezilawulwa kancane, ngaphansi kwe-greenhouse, e-Faculty of Agrarian Sciences Unal Sede Bogotá.
Ngale nqubo, eyenziwa ezivivinyweni ezimbili, kwatholakala ukuthi ukwelashwa kwe-calcium chloride ne-nitrate kungaba kuhle ngokunciphisa imiphumela yokuntuleka kwamanzi, ngoba, nakuba kukhona ukuncipha kwesivuno, lokhu kuphansi kakhulu kunesitshalo esingenawo lowo mnikelo.
Okokugcina, kubonisa ukuthi isinyathelo esilandelayo esingathathwa ngalolu lwazi oluyisisekelo ukuhlola le miphumela esimweni sensimu, okungukuthi, ngaphandle kokumboza, okuyindlela izitshalo zamazambane ezivame ukutholakala ngayo e-Colombia. Nakuba kulolu cwaningo izimo bezilawulwa futhi besifuna ukulingisa okungase kwethulwe emkhakheni, okufanelekile ukuhlola ukuziphatha kokwelashwa ezimeni zangempela kakhulu.
