This study was carried out in 1398 in Seed Physiology and Technology Laboratory of Agriculture Faculty of Mohaghegh Ardabili University to investigate the effect of seed coating and priming on canola seed germination. Experimental treatments included humic acid, seaweed extract, amino acid each at 3 levels, growth stimulus combination (humic acid, seaweed extract, amino acid) at 4 levels, hydropriming with second level humic acid, hydropriming to The second level of seaweed extract and control treatment included 16 treatments. Results showed that seed coating and priming had positive effects on germination percentage and germination rate. Seed coating with level 2 composition of seaweed extract and level 2 humic acid composition with 98% and 97.333% had the highest germination percentage, seed cover with level 2 humic acid and level 1 humic acid respectively The highest germination rate was obtained with 0.031553 and 0.030993 and the lowest seed germination treatments with level 3 of seaweed extract 0.023557. The results showed that control and level 2 humic acid treatments reached 10% germination with 22.920 and 24.886 hours, respectively compared to other treatments
