Analysis of on farm maize production systems and suggestions for improvement
ŠIMKOVÁ, Libuše
Maize is currently one of the most important feed crops. If we want to grow it effi-ciently, we should spend enough time selecting a suitable plot, seed and sowing date. When selecting the sowing date, it is important to achieve a temperature of 8 °C at sowing depth. The maize is sown at a depth of 3-4 cm and can be sown in conventional rows (75 cm), narrow rows (35 cm) or twin rows. Maize is a slow-growing crop, so it is important to pay attention to mechanical or chemical weed control. When harvesting maize for silage, the whole plant can be harvested or the split harvesting technique of CCM and LKS can be used. The hybrids WELAS, PERSEUS and AKANTO were evaluated. WELAS is a double line (Sc), early hyb-rid (FAO 240) and PERSEUS is a triple line (Tc), early hybrid (FAO 250). The PERSEUS hybrid was able to give a higher yield than WELAS in the plots evalu-ated. The hybrid used, agrotechnique and soil moisture availability had the greatest effect on yield.
