In order to determine the suitable fodder beet variety and the best planting and harvest dates in Jiroft region, an experiment was performed. Treatments consisted of two cultivars called 1025 and Lacinia, four planting dates (11 September, 02 October, 22 October, and 11 November) and two harvest dates (5 May and 5 June) evaluated in factorial split plot in 2021-2022 and 2022-23 in the research farm of the South Kerman Agricultural and Natural Resources Research and Education Center. Planting dates were assigned in main plots and harvest dates and genotype were randomly placed in sub-plots. Results of analysis of variance showed that the effect of planting and harvest dates on all studied traits including total yield, root and shoot yield, as well as root and shoot dry matter yield were significant (P ˂ 0.01). The effect of cultivar on root yield, root length, shoot dry matter (P ˂ 0.01) and root dry matter (P ˂ 0.05) was significant. The triple interaction effect was significant on all studied traits, except for shoot yield. Bolting was affected by planting date, variety and their interaction. Lacinia was resistant to bolting in all sowing dates. Comparison of the triple mean effect showed that the highest total yield (187.38 tha-1), root yield (136.77 t ha-1), total dry matter (27.69 tha-1), root dry matter (20.39 t ha-1) and shoot dry matter (7.30 tha-1) was related to the Lacinia on planting date of 10 October and harvesting date of 5 June.
