- ... Plant breeding is a powerful tool for improving nitrogen (N) uptake efficiency and thus reducing the environmental impact relating to crop production. This study evaluated the environmental impact of current barley production systems in two Swedish agricultural areas (South and East) compared with scenarios with improved N uptake efficiency at two levels, in which the fraction of mineral N availab ...

- ... Two field experiments were carried out during 2005 and 2006 to study the effect of four N-fertilization rates (0 (N₀), 100 (N₁₀₀), 200 (N₂₀₀), and 300 (N₃₀₀)kgha⁻¹) on yield, growth, N uptake, and N use efficiency of processing tomato in a silty-clay soil under Mediterranean conditions. N supply positively affected LAI (leaf area index), radiation use efficiency (RUE), above-ground dry weight (DW) ...
