Ukulima i-Canola
I-canola ikhiqizwa kusuka enhle imbewu, ngakho kufanele itshalwe ayijule ngaphezu kwe-3 cm, engacacile kunezolimo eziningi. Ukuze kuhlume kahle, inhlabathi encane kufanele ibe kahle ngaphandle kwama-clods amakhulu, enomanzi futhi engahlanganiswa. Ukuhluma okulindelekile kuzokwenza kube nzima ukuba izithombo zikwazi ukuncintisana nokhula futhi ziphinde zinikeze izifo eziningi.
Izinhlobo
Izinhlobo ezihlukahlukene zitholakala eNingizimu Afrika, zihlukaniswa ngokuvumelana nezidingo zazo zokushisa. Isikhungo Sokucwaninga Ngezolimo sigqugquzela abalimi ukuba bacabangele izifo zezitshalo, ubude obukhulayo, ukukhiqiza okukhona kanye nenkinga yokhula lapho bekhetha izinhlobo kanye nokukhetha ingxube ukunciphisa izingozi zokukhiqiza. Izinsuku kuya kwezimbali zihluka kusukela ezinsukwini ezingu-70 kuya kwezingu-120.
Izinhlobonhlobo Ezintsha
Ukuthuthukiswa kwezinhlobonhlobo ezintsha kuyinkqubo eqhubekayo okuhloswe ngayo ekuthuthukiseni ukuncintisana kanye nokutholakala kwemali yesitshalo. Izinhlobonhlobo ezintsha zihlolwe ukuphikiswa ezinhlobonhlobo noma izifo ezihlukahlukene, noma izakhiwo zezempilo ezingcono.
Ukutshala
Ukuhlwanyelwa kwamanzi kuzohluka kusuka kwelinye ipulazi kuya kwesinye, kuye ngokuthi imishini yokutshala nezimo zenhlabathi. Ngokuvamile, isisindo sembewu yamakhilogremu amathathu kuya kwangu-4 ngehektha ngalinye isetshenziselwa, kanti izitshalo zihlukaniswa ngokulinganayo ukuze zihlume kahle. I-canola ivame ukutshala kusukela ngemva kwemvula yokuqala ngo-Ephreli kuze kufike ngo-June. Isivuno sibhekene nokushisa nokucindezeleka kwesomiso ngesikhathi sokuhluma nokukhula.
Umanyolo
Ngenkathi ukuntuleka kwanoma yikuphi izakhi kuzoba nethonya ekukhiqizeni, i-nitrogen nesulfure yizinto ezibalulekile ezihambisana nokuthuthukiswa kwezivuno. Izindleko ezidingekayo kuxhomeke kwisitshalo esakhiwa ngonyaka odlule, uhlobo lomhlabathi, izimo zezulu, uhlobo lomanyolo osetshenzisiwe kanye nohlobo lokukhiqiza, isibonelo, ngabe izindlela zokulima zasetshenziswayo noma cha.
Buza isiphathimandla esandisiwe noma umanyolo wokufaka umanyolo ukukusiza ukuba uthuthukise uhlelo oluzobhekana nezidingo zokudla okunomsoco wesitshalo sakho ezindaweni ezithile zokukhula. Njengoba umanyolo udinga ukusetshenziselwa lapho isitshalo sidinga kakhulu ukubiza imali. Ukuvimbela ukulimala kwembewu, i-nitrogen ne-potassium kumele ihlukaniswe nembewu kanye ne-nitrogen izicelo kufanele zihlukaniswe zibe izicelo ezimbili kuya kwezintathu.
Izakhi Ezincane
I-canola iyakwazi ukulahlekelwa yi-boron ne-molybdenum futhi inesidingo esiphakeme sesethusi, i-zinc kanye ne-manganese kunezinye izitshalo zokusanhlamvu. Ukuhluleka kungalungiswa ngesikhathi noma ngaphambi kokutshala noma nge-spliys kamuva.
Imali eningi ingasetshenziswa ekudaleni "ukudla okulinganiselayo", kodwa lokhu kusetshenziswa kufanele kube nokulinganisela nokuzuza okungenzeka ukuqinisekisa ukuthi abalimi basenza inzuzo ngaphandle kokukhiqizwa. Amazwe ampofu, isibonelo, azokhiqiza isivuno esibi kungakhathaliseki ukuthi ufaka umanyolo kangakanani kuwo.
