The purpose of this experiment was to evaluate the flora, damage and determine the critical period of weed control in Camelina plant. Research method: This experiment was conducted in the crop year 1402-1401 in the form of a randomized complete block design, which included two groups in three experimental treatments; The first group includes weed interference treatments from the beginning of the growing season to the end of the 2-leaf, 4-leaf, 6-leaf, 8-leaf growth stages, the beginning of flowering, the beginning of fruiting, and then manual weeding of weeds, and the second group of non-interference treatments. Weeds included manual weeding of grasses from the beginning of the growing season to the end of the 2-leaf, 4-leaf, 6-leaf, 8-leaf growth stages, the beginning of flowering, the beginning of fruiting, and then no weed control). The results of this research showed that by reducing the leaf area index of camellia plant and consequently reducing the production of dry matter produced due to the competition of weeds, the yield and performance components were also affected. The highest number of pods per plant was obtained in weed interference treatments up to 2 and 4 leaves, and the least number of pods per plant was obtained in the stages of interference until the beginning of flowering, mid-podding and harvest. The highest number of seeds per pod and the weight of 1000 seeds were obtained in the interference treatment until two leaves of Camelina plant and the least in the interference treatments until the beginning of fruiting. Also, the results showed that increasing the length of the weed-free period (weed control period) increased grain yield and biological yield.
