تأثير إضافة حامض الهيوميك و الرش بمستخلصات الأعشاب البحرية في بعض الصفات المعدنية للأوراق و البذور الجافة لصنفين من البزاليا (Pisum sativum L.)‎

Abstract EN

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.
