A study of levels of trace elements in water and soil of Hamadan Canal and Its Effect on leaves and fruits of Braim and Hillawi Cultivars of date palms

الملخص EN

This work in during : the study of the quality of Shatt Al-Arab water in two locations in Hamadan Canl and the investigation of the effect of this water on two cultivars of date palms planted on the shores of the river.

The following parameters were specified for investigation : pH ; Electric conductivity(EC) ; Total dissolved solids (TDS) ; and concentrations of Cl,Ca,Fe,Cd ions.

The results revealed that Shatt-Al-Arab water in the two locations is saline.

It is also shown that the pH values fall within the normal limits as stated by FAO(International organization of Food and Agriculture).

The T.

D.

S were within the permitted limits ; Cl was in its highest value in station 2 in summer and in its lowest value in station 1 in winter.

Ca and Fe were like Cl in their behaviour whereas Cd was in its highest value in station 1 in winter and in its lowest value in station 1 in summer.

The obtained values in summer, were higher than those obtained in Winter concerning Cl, Ca, Fe and Cd in the Soil of both stations 1 and 2.

The results also revealed significant variation among the cultivars, the seasons and the stations of the study, Al-Hillawi cultivars and winter gave the highest value concerning Fe and Cd in the leaves, station 1 from Cd and station 2 respectively.

The same can be said about overlaps which had significant variation in values.

As far as the fruits are concerned, the highest value was in station 1 from Fe,Cd and the cultivar of date did not have any significant effect.

It was also revealed, in the study, that there was significant effect on the overlaps on the content of the trace elements in the fruits.
