تأثير التباين الملحي في ترب حوض نهر أبي الخصيب في كثافة و إنتاجية نخيل التمر (Phoenix dactylifera L.)‎

الملخص EN

A field experiment was conducted during the growing season 2013, from Feb.

1st to 30th Oct.

at an area of up to 2400 Donems, located in Abu-Al-Khaseeb River Basin (20 km south of region –Basrah) to investigate salinity variations in the soil profile and ground water and their effects on the productivity of date palm.

The results showed that the variation in salinity values of the soils and the groundwater was the largest to stay away from the river Shatt al-Arab, compared to stay away from Abu-Al-Khaseeb River.

However, the significant increase in the salinity of the soil and the ground water values to stay away from the course of rivers, as well as increase towards the end of the growing season C.

The results showed a decrease in the total yield of date palm in Abu-Al-Khaseeb River basin significantly as a result of increasing distance from the Shatt al-Arab as well as increasing the distance from Abu-Al-Khaseeb River.

The d2, d3 and d4 sites recorded a significant decrease in productivity values were (27.13 and 59.16 and 85.75 %), respectively, compared to the d1 site which was closed to the Shatt al-Arab , and the number of date palm decreased significantly as a result of distance from the Shatt al- Arab.

Also, the average of the intensity of date palm was 20 palms Dunam-1, whereas the average of the closest region was 53 palms Dunam-1.

However, it is necessary using management of soil and irrigation related with salinity conditions and cultivation of Date Palm to one Km of Shatt al-Arab.
