Zvinokurudzirwa kuti varimi ve canola vashandise zvinodzora kukura kwezvirimwa (PGRs) kuzvirimwa zve canola zvinokura nekukurumidza kuti goho riwedzere uye kuti zvirimwa zvigare zvakanaka.
Mumatsutso ano, zvirimwa zvinosiyana kwete chete muhukuru, asiwo muzvikamu zvekukura: kubva pazvirimwa zvine mashizha matanhatu chaiwo kusvika kune zvirimwa zvine macotyledon chete.
Saka, manejimendi achawedzera kuoma uye achada nzira chaiyo yekushanda,” akadaro Nigel Scott, maneja wehunyanzvi hwedunhu kuProcam.
Kunyangwe varimi vasingade kuisa mari, vamwe vakarasikirwa negoho guru zhizha rapfuura nekuda kwekushaikwa kwekudyara uye goho diki mwaka wapfuura.
Saka sei nyanzvi dzezvekurima dzichiti goho rakasiyana kudaro? Vachitarisa kumashure mumakore gumi apfuura, Nigel anotaura kuti avhareji yezuva rekudyara ivhiki rechitatu raNyamavhuvhu.
Zvisinei, nekuda kwekutyisidzirwa nezvipembenene zvekabheji, mazuva ekudyara akamiswa kare kana kunonotswa kudzivirira mamiriro ezvinhu apo chirimwa chiri muchikamu checotyledon apo zvipembenene zvakakura zvinoonekwa pakupera kwaNyamavhuvhu.
Gore rino, kudyara kwakapedzwa kare mune dzimwe nzvimbo. Akanongedzera kudunhu rake, Durham, uko, semamwe matunhu eEngland, kukohwa kwakapedzwa nguva isati yakwana.
Zvirimwa zvine mukana wekuwana mvura zvinokura nekukurumidza. Zvisinei, munzvimbo dzine kushomeka kwemvura kana ivhu rakaoma, nguva yekumera inowedzera.
Saka, kukura kwezvirimwa kunosiyana zvichienderana nekuwanikwa kwemvura; zvimwe zvirimwa zvinokura mashizha chaiwo mana, mashanu, kana matanhatu, nepo zvimwe zvichikura macotyledon chete.
Miti yekupedzisira yakadyarwa mushure mekutama kwaGunyana kusvika pari zvino yakabereka shizha rimwe chete rechokwadi. Chinonetsa ndechekuti Nigel atanga kuona huwandu hwakawanda hwezvipembenene zvikuru.
"Saka, kunyangwe mumunda mumwe chete, takaona zvirimwa pamatanho matatu akasiyana ekukura."
Pazvirimwa zvinokurumidza kuibva, varimi vake vanoronga kushandisa zvinodzora kukura kwezvirimwa—chinhu chavasina kuita kwenguva yakareba.
Akataura kuti varimi vanofanira kushandisa zvinodzora kukura kwezvirimwa (PGRs) izvozvi kuti vawedzere kushanda kwavo nguva isati yakwana.
Zvakanaka kuti fetiraiza iyi ishandiswe kana chirimwa chave nemashizha echokwadi mana kusvika matanhatu (pakati paGumiguru). Zvinodzora kukura kwemiti zvinogona kudzvinyirira kukura kwezvikamu zviri pamusoro pevhu uye kukurudzira midzi (ona dhayagiramu).
Izvi zvinotsanangurwa nekuti kana petiole yakareba, njodzi yekupararira kwechirwere ichi kusvika padzinde inoderedza.
"Dambudziko iri rinowanzoitika muminda midiki yakarapwa nemishonga inouraya fungi yakaita sedifenoconazole."
Pakupedzisira, akapa zano rekuti zvirimwa zvinokura zvishoma nezvishoma zvifukidzwe nevhu nekuti tembiricha yevhu ichadzikira uye zvichafanira kuunganidza biomass mukugadzirira mwaka wechando.
"Kunyangwe zvirimwa zvakakura zvinoda zvimwe zvinovaka muviri, kunyanya manganese neboron, kuti zvibereke goho guru."
Chimwe chezvinetso zvikuru mumatsutso aya ndechekuona nguva yakakodzera yekuisa clethodim mukurwisa sora, tichifunga nezvemhando dzakasiyana dzezvirimwa zvinorimwa.
Kuisa mishonga yekuuraya zvipembenene panguva yakakodzera kwakaoma nekuti kunogona kukanganisa nzvimbo huru dzezvirimwa. "Saka, varimi vanofanira kunyatsoteerera nguva yekushandisa mishonga," akadaro Nigel.
Anotaurawo kuti kuwedzera kwehuwandu hwenitrogen yasara muvhu nekuda kwekusanaya kwemvura munguva yezhizha kwakakurudzira kukura kwezvirimwa. Kukwira kwekushisa kwevhu kunorevawo kuwedzera kwemineral muvhu.
"Buckwheat inokura yakareba kupfuura rapeseed, uye nekuda kwemakwikwi aripo pakati pezvirimwa, inotsivawo rapeseed. Pasina buckwheat, rapeseed haingakure yakareba kudaro."
