Dynamics of the nitrogen uptake by spring barley at injection application of nitrogen fertilizers
Original language description
Influence of CULTAN system on the nitrogen uptake by spring barley was observed at 5-year small-plot field experiments. Nitrogen uptake by CULTAN-fertilized plants was more even during vegetation period. Post-heading nitrogen uptake and contribution of nitrogen translocation to total nitrogen in grain did not differ among both nitrogen fertilization treatments. Increase in grain size of spring barley by the CULTAN system can be explained by tendency to lower number of ears per area rather than by prolonged nitrogen uptake from soil. Lower protein content in grain of CULTAN-fertilized spring barley can be caused by increase in grain retained on a 2.5 mm sieve and also decrease in total nitrogen concentration in above-ground biomass at BBCH 51. No significant effect of CULTAN treatment on nitrogen use efficiency and nitrogen uptake efficiency was recorded. Higher nitrogen utilization efficiency at CULTAN treatment could be explained by lower grain protein content compared to conventional
