Nitrogen fertilization does not affect micronutrient uptake in grain maize (Zea mays L.)

Popis výsledku v původním jazyce

Due to continuous single nitrogen fertilization, we hypothesized a built up deficiency of micronutrients in crops that would limit plant growth and crop quality. In 2 year field experiments using urea N fertilized grain maize (Zea mays L.), hybrid KWS 2376 at 0, 120 and 240 kg N/ha crop uptake of Zn, Mn, Cu and Fe was studied at DC 32, DC 61 and in the grain harvested. Micronutrient contents at DC 32 stage -- 1st node (aboveground phytomass) and DC 61 flowering (ear leaf) were all at levels indicative of adequate micronutrient supply to the crop. At both sampling occasions the Fe:Zn and Fe:Mn ratios were adequate implying that Fe did not inhibit the uptake of Zn and Mn. The application of nitrogen increased the Fe content at the 1st sampling in both years; in the second year the same was also the case for the Zn content. Nitrogen nutrition increased the contents of Mn and Fe at the 2nd sampling only in year 2; in the other treatments no changes were observed in the micronutrient conten
