الملخص EN

A field experiment was carried out in Al Bandar, Samawa city in the autumn season of 2016.

Iron fertilize was used at rates of 0, 30, 60, 120 mg.

l-1, and Zinc fertilizer concentrations of 0, 15, 30, 60, Zn mg.

l-1.

The iron significantly increased the plant content of elements K, P, N Concentration index (60 mg Fe.

-1 L) An increase of N and K elements by 27 and 55% sequentially, concentration record (30 mg.

l-1 Fe).

An increase of 36% of the P element was also observed.

Zinc concentration of (30 mg Zn L-1) increased the plant content of N and P elements by 29% and a concentration of 15 mg / An increase of 46% K.

All overlaps also recorded an increase in element concentrations N, p in plant concentration.

The concentration of Fe3 (120 mg.

l-1 Fe) was higher than that of iron orbed by 29% compared with zinc, and zinc was significantly increased in the amount of iron orbed.

The concentration of Zn3 (60 mg.

l-1 Zn) was the best, as compared to other treatments.

120 mg.

l-1 Fe gave the highest grain yield (5.90 t).

The highest mean of 5.96 tc-1, obtained with concentration Zinc was 60 mg.

l-1 Zn, while the combination (120 Fe + 60 Zn) recorded the highest grain yield of 6.28 tons
