They were distributed throughout the study area in order to take into account the variability of ecological and Agronomic factors. The results obtained by the Correspondence Factor Analysis (CFA) highlight two groups of surveys including two groups of species. These results explain the distribution of citrus weeds in the Skikda region according to climate and edaphic conditions. The appearance of weed species was selective, for example, Oxalis Latifolia. Kunt. is a very common and abundant species in the more or less humid northern zone, whereas it is almost absent in the southern zone of the study area. On the other hand, Papaver rhoeas. was frequent and abundant in the southern zone, which is a somewhat dry zone, was almost absent in the northern zone.
