Figure 10

Number of first order lateral roots of Hordeum vulgare plants for treatments control (“C”), urea (“U”) and urea with nitrification inhibitor (“U+NI”), separated for three depths for each harvest. Top layer (0–5 cm) is above fertiliser zone, bottom layer (10–23 cm) is below fertiliser zone. Statistical comparison is performed for number of first order laterals per layer between treatments. Significant differences (p < 0.05) are indicated by different letters. Bottom layer at 16 DAP was too complex for a reliable analysis; dashed lines in the boxplots represent mean values while solid lines represent the median.
