Abstract:

A field trial to determine the effect of nitrogen fertilizer on growth, yield and quality of six chicory cultivars viz., 'Monivip', 'Castel Franco', 'Anivip', 'Foresto', 'Palla rossa' and 'Verona' was conducted at the Experimental Station of the Biotechnical Faculty in Ljubljana, Slovenia. Nitrogen was applied as KAN 27% at 0, 50, 100, 150 and 200 kg N/ha in two equal doses

(half as basal and half as top dressing).

As the level of nitrogen fertilizer was increased, a decrease of dry matter and head firmness were observed. However, an increase in fresh weight of heads and plant height were obtained, as the rate of nitrogen fertilizer was increase from 0 to 150 kg N/ha. Further increase however led to a decrease in these parameters. Among the cultivars the highest fresh weight of heads were obtained from cv. 'Verona' and the most compact heads, were produced by cv. 'Palla rossa' and cv. 'Foresto'.
