Description
  • Seeds of rapeseed require (compared to cereals grain) very small amount of water for germination, but they are demanding in air. So we sow them shallow (1-2 cm) and they germinate mostly from dew and rainfall. On the contrary cereals germinate well fromdepths of 3-8 cm, they are less demanding in air, but require plenty of water usually from soil capillarity (VAŠÁK a kol., 2000). The clods after drying (after 1-2 days after ploughing) cold down during the night. Thus they reached the temperature of thedew-point and condensated the dew-water. Main problem with spring poppy is a low stress resistance at the beginning of growth. This is caused by small size of seeds and by poppy sowing in early spring, when there are often dry frosts or soil crust is formed.

  • Koncetrace řepky v České republice překračuje od roku 1999 11% z orné půdy (ČSÚ 2002). Extrémní výměra a nutnost vysoké produktivity práce vedou k pěstování řepky bez orby po ozimé pšenici a jarním ječmeni. Vašák a kol. (2000) odhaduje podíl řepky vysévané po obilovinách na asi 90%. Kolem 50-60% řepky se pěstuje bez orby. Řepka často špatně vzchází a je extrémní výskyt obilí jako plevele v řepce.I když se fyziologie klíčení řepky a obilí zásadně liší ( Vašák a kol. 2002), používá se pro založení porostuřepky stejná agrotechnika jako pro obiloviny. To podporuje obilí jako plevel v řepce. Základním problém u jarního máku je nízká odolnost vůči stresům na počátku růstu. To je dáno jednak malou velikostí semen a jednak potřebou mák vyset na jaře co nejdříve, kdy často přichází suché mrazy, nebo se tvoří půdní škraloup. (cs)
