| dc.description.abstract | In the present study, the effect of nitrogen (N) application rate on plant growth and quality of Cichorium spinosum L. was examined. Four nitrogen rates were applied, namely: a) Control (no added N), b) 200 mg L-1 of total N, c) 400 mg L-1 of total N, and d) 600 mg L-1 of total N. Plant growth (rosette diameter, number of leaves, SPAD index, and fresh and dry weight) and chemical composition of leaves (sugars, organic and fatty acids, tocopherols, minerals and nitrates content) were recorded. Fresh weight increased up to 400 mg L-1, whereas dry weight was not affected by N rate. Plants treated with N formed larger rosettes and more leaves comparing to control treatment, except for the rate of 600 mg L-1 where number of leaves did not differ from control. SPAD index was higher at the rate of 600 mg L-1. The application of N resulted in higher content of sugars, whereas tocopherols showed a significant decrease. In conclusion, the application of nitrogen rates up to 400 mg L-1 is suggested for high yields without compromising the quality of the final product. | pt_PT |
