Title
Effect of Sowing Method, Plant Density and Harvest Date on the Yield and Quality of Chicory (Cichorium intybus L.)
Authors
Abstract
To evaluate the effect of sowing method, plant density and harvest time on the yield traits of Chicory, an experiment was conducted during 2012 in Qazvin Sugar Factory Research Station. crop varieties of Chicory in two sowing method(direct sowing and explanting) and three plant densities (6, 12, and 18 plants per square meter) in three harvest dates (31 August and 20 September and 11 October) were evaluated using a factorial design with three replications. The result of ANOVA showed that the main effect of sowing method was significant for most traits including root yield, inulin content and inulin yield. Inulin contentwas not affected by the main effect of plant density but this main effect was significant for both, root yield
and inulin yield. The delay in harvest time caused a significant increase in the inulin content and inulin
yield; however, it did not have a significant effect on the root yield of Chicory. Comparing notes sowing
method × plant density interaction showed the highest root fresh weight (270.2 g) with explanting and
density of 18 plants per square meter and maximum diameter of the root of explanting with density 6 plants
per square meter. The highest content of inulin (14.9%) of harvest in 11 October and explanting total
Fructose (16.7%) was obtained from direct sowing and harvest on 11 October. in general, explanting and
density of 18 plants per square meter and harvest on 11 October that the potential yield and the percentage
was higher inulin recommended.
