This study was implemented in the Horticultural Field, College of Agric.

& forestry, Mosul Univ.

, Iraq, during the growth seasons (2012/2013, 2013/2014) to study the effect of humic acid and some seaweed extracts on some yield of dry seeds 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-1), spraying seaweed extracts Algaren and ALG 6000 at conc.

(2ml.

l-1) for each one, spraying a mixture of the two extract at conc.

(1.

5ml.

l-1.

Algaren + 1.

5ml.

l-1.

ALG 6000) in the two mentioned cultivars.

Humic acid was added in three doses (before sowing, after30and 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 all fertilization treatments upon the control treatment in most traits of seeds yield.

The humic acid treatment registered the best performance in the yield and its components which had a significant surpassing in most traits over Algarea and ALG6000 treatments, also was superior on the mixture of the two extracts in traits (less no.

of days for ripening the 1st.

pod in the 1st.

season, no.

of seeds pod-1in both growing seasons, seed yield of plant & hectar during the two seasons).

On the other hand.

the mixture treatment gave better results in the yield traits than application of each extract alone.

The results exhibited that Mezza Rama cv.

was superior over Little Marvel cv.

in the mostdry seeds yield characters as in (pod's length & weight, weight of 100 seed in both seasons, no.

of seeds pod-1, seeds yield plant-1 and hectar-1 in the two seasons).

Interaction treatments between adding H.

A.

to the soil and spraying a mixture of the two extracts with the cultivar Mezza Rama cv.

.

in addition to the interaction treatment between H.

A.

with Little Marvel cv.

had a significant increase in most yield traits.
