EFFECTS OF PLANT DENSITY ON ROOT YIELD AND LEAF AREA IN CHICORY (CICHORIUM INTYBUS L.)
Chicory (Cichorium intybus L.) belonging to the Asteraceae family has prominent medicinal properties and its root has been reported to be the most abundant source of inulin which has valuable applications in pharmaceutical and food industries. It also contains important compounds such as bitter sesquiterpene lactones, cumarins, flavonoids and vitamins. Due to its various uses as a vegetable and a medicinal plant and considering that it is not yet cultivated in Iran, we endeavored to investigate the effects of plant density on the root yield and characteristics as well as leaf area in two cultivars of chicory. The experiment was conducted in Khalat-Pushan Agricultural Research Station (KARS), University of Tabriz, Tabriz, Iran. Four intra-row spacing (5, 10, 15, and 20 cm) and two cultivars (Pagana and Yellow Star) were compared in a randomized complete block design with three replications. The results showed significant differences in leaf area per plant between cultivars and plant densities. The intra-row distance of 20 cm and Pagana had the highest leaf area per plant. There were significant differences in root length and diameter with plant density but not between cultivars. Moreover, differences in root fresh weight per plant either between cultivars or plant density appeared to be significant. In conclusion, the cultivar Pagana was identified as the highest in root fresh weight per plant and when cultivated at 15 and 20 cm spacings.
