In order to study effect of planting date and seed priming on some morphological characteristics, sugar yield and yield sugar yield components of sugar beet (Beta vulgaris), An experiment was conducted on a farm land in Mahabad city at 2020 growing season. The experiment design was split plot based on randomized complete block with four replications. planting date (March 5, April 3 and May 4) assigned to main plots, and priming types (Salicylic acid, hydropriming, chitosan and control (no priming)) assigned to sub plots. In this study, the traits of chlorophylla and chlorophyllb content, carotenoids, relative leaf water content sugar content, white sugar content, root yield, sugar yield and white sugar yield were measured. In this study, the highest content of chlorophyll a, chlorophyll b, carotenoids, leaf area index, was allocated to the March 5th planting time. Also, salicylic acid priming and hydropriming had the highest content of chlorophyll a, chlorophyll b, carotenoids, leaf area index. Among the interactions of planting time with priming treatments, the highest relative water content of leaves (75.50%) , root yield (60.1 t / ha), sugar content (19.49), white sugar content (15.02), sugar yield (10.91 tons per hectare) and white sugar yield (8.31 tons per hectare) were allocated to April 3 planting time and priming with salicylic acid.The results also showed that salicylic acid priming and hydropriming at all planting times increased the white sugar yield compared to the control treatment and moderated the adverse effect of delay at planting time on the white sugar yield.
