Camelina is one of the plants that it seed yield is highly dependent on planting date. This experiment was conducted using randomized complete blocks design with three replications in research farm of Fasa Branch, Islamic Azad University, Fasa, Iran in 2018 and 2019 cropping seasons. Planting dates at six levels; November 1, 11, 21 (autumn sowing) and February 20, March 1 and 11 (winter sowing). The results showed that the autumn planting on November 1 (with 1550 GDD) had the highest seed yield (2373 kg.ha-1) and oil yield (621.kg ha-1). Harvest index of autumn planting was 4.34% higher than winter planting. Thousand seed weight was not affected by planting date. The highest water productivity of 0.18 kg oil ha-1.m-3 was obtained in February 1 planting date. Analyisis of camellia seed oil revealed that linoleic acids (C18: 2) and oleic (C18: 1) had the highest proportion (30.2%) of fatty acids. the proportion of erucic (C22: 1), eicosenoic (C20: 1) and stearic (C18:0) acids which were affedted by low environmental temperatures in autumn planting dates increased compared to winter planting dates. According to results of this experiment, autumn planting of camellia had higher seed yield with higher oil quality. With delaying planting date, especially in winter, seed developmental stage coinicded with terminal heat that reduced seed yield and seed oil content. However, early winter planing had the highest water productivity.
