One way to introduce a new crop to a new region is to find an adaptable variety. Moreover, a suitable planting density is one of the key factors which directly affect yield production. Cichorium endivia is one of plants which grow well in soils with residual nitrogen from the pervious cropping season. The objective of this study was to assess the influence of different varieties and planting densities on the growth and yield production of Cichorium endivia L. To do this, a split plot experiment in the form of a randomized complete block design was used with three replications. The three varieties (Witloof Zoom F1, Witloof Flash F1 and Witloof Mechelse Middelvraeg) were in the main plots and the three planting densities (with intra row spacing of 20, 25 and 30 cm) were in sub plots. Traits were measured in two stages; the first stage in field phase and the second stage in greenhouse phase. Finally, the results indicated that Witloof Flash F1 with 30 cm spacing was the best variety with the heighest yield.
