Efficiency of Fertilization and Utilization of Nitrogen and Sulphur by Spring Wheat

摘要

The aim of our study was to evaluate the effects of nitrogen (N) and sulphur (S) fertilizer on harvest index (HI), agronomic efficiency (AE), physiological efficiency (PE), utilization (U), and final efficiency index (EFI). We conducted a field experiment (2009-11) in southeastern Poland on Cambisols (WRB 2014). The experiment included two variables: N fertilization (0, 40, 80, and 120 kg/ha) and S fertilization (0 and 50 kg/ha).
