Cultivation factors have a significant effect on the yield and yield security of maize. Ensuring a suitable green crop is important. Tricultural crop rotation (pea–wheat–maize) in the average of 25 years provided a 2 t ha -1 higher yield compared to monocultural cultivation. A harmonious NPK nutriment supply determines yield and yield security, which can be especially realized by means of the application of precision cultivation technologies. Under average circumstances N 80 kg ha -1 , P 2 O 5 50 kg ha -1 , K 2 0 60 kg ha -1 active ingredient is the agro-ecological dosage of artificial fertilizer. Plant density is a factor that determines yield. Optimal plant density – beside the genetic characteristics of the hybrid – is mostly influenced by the level of water and nutriment supply.
