The effect of nitrogen fertilization on root length (RL) distribution of winter wheat (Triticum aestivum L.) was investigated. The study was conducted in Prague-Ruzyne on clay loam Chernozemic soil in the years 1996–2003. Two (N0, N1) and three (N0, N1, N2) treatments, unfertilized (N0), fertilized with 100 kg (N1) and 200 kg N/ha (N2) were studied in 1996–2000 and 2001–2003, respectively. Nitrogen rate 100 kg/ha had no effect on RL in soil layers (P > 0.1) in years 1996–2000 and 2002–2003 and there was not significant interaction between N treatment and soil layer except for year 1998 (P < 0.01). Nitrogen fertilization affected RL distribution significantly (P = 0.013) only in 2001 due to reduction of root growth in subsoil layers in treatment N2 (200 kg N/ha) in comparison with N0 and N1. The effect of N fertilization on total RL in rooted soil volume was insignificant. There was a significant effect of year on total RL (P < 0.01) but not of interaction of year and N treatment. Roots reached, with the exception of two years, the depth between 100 and 130 cm. Nitrogen fertilization (N1) had no effect (P = 0.59) on rooting depth (RD) in years 1996–2000 but there was a significant effect of interaction between year and N fertilization on RD (P < 0.01). In the second experimental series (2001–2003) N fertilization rate 200 kg N/ha significantly reduced maximum RD (P < 0.01) in comparison with N0 and N1. The year had highly significant effect on RD.

The after-effects of pre-preceding crops (second year), i.e. legumes and spring wheat, and nitrogen fertilization rate (0, 60, 120 and 180 kg N/ha) on the yield and chemical composition of winter wheat grain were analysed in a field experiment conducted in 2013–2015. Winter wheat was characterized by higher yield when sown after blue lupine (increase of 0.23 t/ha) and faba beans with a determinate growth habit (increase of 0.37 t/ha) than after spring wheat. Grain yield increased significantly with a rise in nitrogen fertilization rate (by 2.03, 3.47 and 4.02 t/ha, respectively). The species of pre-preceding crops had no significant effect on the phosphorus, potassium, magnesium and calcium content of winter wheat grain. Winter wheat grown after faba beans with an indeterminate growth habit was most abundant in nitrogen. The applied nitrogen fertilizer rates did not modify the concentrations of phosphorus, magnesium and calcium in winter wheat grain. The nitrogen content of grain increased significantly with a rise in nitrogen fertilization rates. A significant increase in manganese and zinc levels was observed when spring wheat was the pre-preceding crop and the iron content of grain increased significantly when winter wheat was grown after peas and blue lupine.
