Nitrogen efficiency of spring barley in long-term experiment

Popis výsledku v původním jazyce

The aim of this study was to evaluate nitrogen (N) efficiency from different organic and mineral fertilizers applied to the spring barley. Dry matter (DM) yield, N content and N uptake of spring barley from 16 years of experiments at two sites in the Czech Republic with different soil and climatic conditions were analyzed. For assessing of nitrogen efficiency Nitrogen utilization efficiency (NUtE, kg/kg), Recovery efficiency of applied N (REN, %), Agronomic efficiency of applied N (AEN, kg/kg) and Summary N balances (??N, kg/ha) were observed. Six fertilizing treatments were utilized: no fertilization (Control), sewage sludge (SS), farmyard manure (FYM), N in mineral fertilizers (N), NPK in mineral fertilizers (NPK) and N in mineral fertilizers + straw(N+ST). Yields were about 68 % higher at NPK (S1 site) and 55 % at N+ST (S2 site) in comparison with Control. The highest NUtE was recorded at both locations after application of FYM. Higher NUtE from mineral fertilizers was obtained at
