Repka ozimná
Repka ozimná (Brassica napus) je najvýznamnejšia olejnina v Česku, pestovaná na olej s nízkym obsahom erukovej kyseliny (potravinársky a technický olej, bionafta) a bielkovinové šroty. Vysieva sa na konci leta a po prezimovaní tvorí husté porasty zberané v júni–júli.

Agronómia
- Výsevok
- 40–60 klíčivých semien/m² (cieľová hustota 30–50 rastlín/m² po prezimovaní)
- Hnojenie
- N 150–200 kg/ha celkovo — jesenná štartovacia dávka síry a časti N, jarné delené dávky N + síra 30–40 kg/ha
- Výnos
- 3–5 t/ha
- Zber
- jún–júl (pri vlhkosti semien <9 %)
- Využitie
- rastlinný olej (potravinársky, bionafta), bielkovinový šrot (krmivo), med (medonosná plodina)
Osevný postup
- 1 Predplodina
Repka ozimná sa nesmie vrátiť na ten istý pozemok skôr ako po 4 rokoch. Najlepšie predplodiny sú ozimné obilniny. Vylúčiť predplodiny z čeľade kapustovité.
- 2 Príprava pôdy a sejba
Skorý zber predplodiny a rýchla príprava kvalitného sejbového lôžka do hĺbky 2–3 cm. Sejba 15. augusta – 5. septembra, výsevok 40–60 klíčivých zŕn/m².
- 3 Jesenné hnojenie
Pred sejbou alebo pri sejbe aplikovať P, K a síru; štartovacia dávka N (30–40 kg/ha) podporí vývoj do prezimovania. Porasty vstupujú do zimy v ružicovom štádiu.
- 4 Jarné hnojenie
Hlavná N výživa na jar v 2–3 dávkach (celkovo 120–160 kg N/ha). Síra 30–40 kg/ha podporuje úrodu a obsah oleja.
- 5 Ochrana rastlín
Fungicídy (fómová hniloba, sklerotíniová hniloba), insekticídy (byľomorka, krytonosce stonkové, blyskáčik repkový), herbicídy jeseň + jar.
- 6 Zber
Zber priamy alebo s podsúšaním. Pri priamom zbere čakať na vlhkosť semien pod 9 %. Straty zo šešúľ minimalizovať správnym nastavením mláťačky.

Časté otázky
Kedy sa seje ozimná repka?
Optimálny termín sejby je 15. augusta – 5. septembra. Neskorá sejba oslabuje rastliny pred zimou a znižuje prezimovanie aj úrodu.
Prečo je síra dôležitá pre repku?
Síra je nevyhnutná pre syntézu aminokyselín a glukozinolátov. Nedostatok síry znižuje úrodu aj obsah oleja. Odporúča sa 30–40 kg S/ha, najlepšie vo forme síranu.
Aký dlhý musí byť osevný postup pri repke?
Repka a ostatné kapustovité plodiny nesmú na ten istý pozemok skôr ako po 4 rokoch, ideálne po 5–6 rokoch, kvôli hromadeniu patogénov (fómová hniloba, sklerotíniová hniloba) a škodcov.
Aký výnos semena dosahuje repka ozimná?
Priemerný výnos v Česku je 3–4 t/ha, v priaznivých podmienkach a s dobrou agrotechnikou možno dosiahnuť 4–5 t/ha.
