Abahinzi b'imbuto z'umurabe baragirwa inama yo gukoresha uburyo bwo kugenzura imikurire y'ibimera ku bihingwa bifite igipimo cyo gukura kiri hejuru.

Ni byiza ko abahinzi ba canola bakoresha uburyo bwo kugenzura imikurire y'ibimera (PGRs) ku bihingwa bya canola bikura vuba kugira ngo umusaruro urusheho kwiyongera kandi bikomeze guhindagurika.
Muri iki gihembwe cy'impeshyi, ibimera ntibitandukanye gusa mu bunini, ahubwo biratandukanye no mu byiciro by'iterambere: kuva ku bimera bifite amababi atandatu nyayo kugeza ku bimera bifite cotyledons gusa.
Bityo rero, imicungire izarushaho kuba ingorabahizi kandi bizasaba uburyo bwihariye bwo gukoresha aho hantu,” ibi ni ibyatangajwe na Nigel Scott, umuyobozi ushinzwe tekiniki mu karere muri Procam.
Nubwo abahinzi batifuzaga gushora imari, bamwe babuze umusaruro mwinshi mu mpeshyi ishize bitewe n’ibura ry’ishoramari n’umusaruro mubi mu gihembwe gishize.
None se kuki abahanga mu by'ubuhinzi bavuga ko umusaruro uhindagurika? Mu myaka icumi ishize, Nigel agaragaza ko igihe cyo kubiba impuzandengo ari icyumweru cya gatatu cya Kanama.
Ariko, kubera ikibazo cy’udusimba two mu bwoko bwa cabbage stem fleake, amatariki yo kubiba yimuwe mbere cyangwa agasubikwa kugira ngo hirindwe ko umusaruro uba uri mu cyiciro cya cotyledon ubwo udusimba two mu bwoko bwa fleake dukuze tugaragara mu mpera za Kanama.
Muri uyu mwaka, kubiba byarangiye kare mu bice bimwe na bimwe. Yerekeje ku karere ke, Durham, aho, kimwe n'ahandi mu Bwongereza, gusarura byarangiye mbere y'igihe cyari giteganyijwe.
Ibimera bifite amazi bikura vuba. Ariko, mu turere dufite ibura ry'amazi cyangwa ubutaka bwumye, igihe cyo kumera kiriyongera.
Bityo, gukura kw'ibihingwa kuratandukanye bitewe n'amazi ahari; ibihingwa bimwe bikura amababi nyayo ane, atanu, cyangwa atandatu, mu gihe ibindi bikura gusa amababi ya cotyledon.
Itsinda rya nyuma ry'ibimera byatewe nyuma yo kwimuka kwa Nzeri kugeza ubu ryatanze ikibabi kimwe cy'ukuri gusa. Igiteye impungenge ni uko Nigel yatangiye kubona umubare munini w'udukoko dukuze.
“Rero, ndetse no mu murima umwe, twabonye ibimera mu byiciro bitatu bitandukanye byo gukura.”
Ku bihingwa byera kare, abahinzi be barateganya gukoresha uburyo bwo kugenzura imikurire y’ibimera—ikintu batari bagikorera igihe kirekire.
Yavuze ko abahinzi bagomba gukoresha uburyo bwo kugenzura imikurire y'ibimera (PGRs) ubu kugira ngo bongere umusaruro wabo mbere yuko bitinda.
Byaba byiza iyi fumbire ikoreshejwe igihe ikimera gifite amababi ane kugeza kuri atandatu nyayo (hagati ya Ukwakira). Ibikoresho bigenzura ikura ry'ibice biri hejuru y'ubutaka bishobora kugabanya ikura ry'ibice biri hejuru y'ubutaka no gutuma imizi ikomera (reba igishushanyo mbonera).
Ibi bisobanurwa n'uko uko petiole iba ndende, niko ibyago byo kwandura indwara ku giti bigatera ibisebe bigabanuka.
"Iki kibazo kigaragara cyane mu mirima mito yavuwe imiti irwanya udukoko nka difenoconazole."
Amaherezo, yatanze inama yo gufumbira ibihingwa bikura buhoro buhoro kuko ubushyuhe bw'ubutaka buzagabanuka kandi bizakenera kwegeranya ibimera mu rwego rwo kwitegura igihe cy'itumba.
"Ndetse n'ibihingwa byeze bisaba intungamubiri zimwe na zimwe, cyane cyane manganese na boron, kugira ngo bitange umusaruro mwinshi."
Imwe mu mbogamizi zikomeye muri iki gihembwe cy'impeshyi ni ukumenya igihe cyiza cyo gukoresha clethodim mu kurwanya ibyatsi bibi, bitewe n'ubwoko bwinshi bw'ibihingwa bihingwa.
Gukoresha imiti yica udukoko ku gihe biragoye kuko bishobora kwangiza imirima minini. Nigel yagize ati: “Kubera iyo mpamvu, abahinzi bagomba kwitondera cyane igihe cyo gukoresha imiti.”
Avuga kandi ko kwiyongera k'urugero rwa azote rusigaye mu butaka bitewe n'amapfa yo mu mpeshyi byatumye ibimera bikura. Ubushyuhe buriyongera mu butaka nabwo bugaragaza kwiyongera kw'amabuye y'agaciro.
"Ingano y'ingano ikura cyane kurusha imbuto za rapeseed, kandi bitewe n'irushanwa hagati y'ibihingwa, inasimbura imbuto za rapeseed. Iyo hatabayeho imbuto za rapeseed, imbuto za rapeseed ntizakura cyane."
