- Abstract
The influence of nitrogen injection on winter wheat (Triticum aestivum L.) yield, yield formation, stem lodging, fungal diseases incidence and qualitative parameters of grain was studied. The injection of all nitrogen applied in one dose, so-called CULTAN (Controlled Uptake Long Term Ammonium Nutrition) system, was compared with nitrogen split application during the years 2009-2013 in small-plot field experiments at three experimental sites in the Czech Republic (central Europe). Nitrogen dose applied conventionally on soil surface was split into three partial applications. The CULTAN fertilization was carried out at the beginning of spring vegetation instead of usual term, i.e. the end of tillering (BBCH 29). Grain protein content was significantly lower and grain starch content significantly higher in wheat treated with the CULTAN system compared to the nitrogen split application. Nevertheless, the CULTAN treatment did not lead to significantly higher starch yield in comparison with the nitrogen split application. Plants per m2, number of ears per m2 and thousand grain weight were not significantly different among nitrogen treatments. Significantly lower number of grains per ear was recorded while using the CULTAN system compared to the nitrogen split application when 150kg N/ha was applied, but this had no significant impact on grain yield. No positive effect of the CULTAN system on both stem lodging of winter wheat and incidence of powdery mildew as well as Septoria tritici blotch was confirmed.
