This study was implemented in the Horticultural Field, College of Agric. and forestry, Mosul Univ., Iraq, during the growth seasons (2021/2013, 2013/2014) to study the effect of humic acid and some seaweed extracts on vegetative growth traits of two pea cultivars (Mezza Rama & Little Marvel) . The study compromised 10 treatments (the control , adding H.A. to the soil at conc. ( 2gm / l.), spraying seaweed extracts Algaren and ALG 6000 at conc. (2cm3/l.) for each one, spraying a mixture of the two extract at conc.(1.5cm3 / l. Algaren + 1.5cm3 / l. ALG 6000) in the two mentioned cultivars (5×2). Humic acid was added in three times (before sowing , after 30 and 60 days from sowing) , whereas seaweed extracts were sprayed three times after (40, 95 , 125 ) days from sowing. The experimental design was Randomize Complete Block Design with three replications. The obtained results indicated that : The significant superiority of most fertilization treatments upon the control treatment in trait of weight dry roots . A significant and greatest values in most mineral content traits of leaves and seed was registered by adding H.A. to the soil with exception of ( N % in the leaves and seeds in both seasons) . The two pea cultivars exhibited variation in mineral content of leaves and seeds . where Mezza Rama cv. was superior in traits of (P % of leaves in the 1st. season . K % of leaves and N % of seeds in the 2nd. Season . K % of seeds in both seasons) and Mezza Rama cv. was superior in trait of weight dry roots in both seasons . Whereas the Little Marvel cv. was the best in (N % of leaves in the 2nd season . P % of seeds in the two seasons) . The interaction treatments between adding H.A. to the soil with both Mezza Rama cv. &Little Marvel cultivars had the highest significant effect in most mineral content traits of leaves , seeds and trait of weight dry roots in both seasons
