Evaluation of the effect of nano-fertilization and disper osmotic in treating the salinity of irrigation water on the chemical and mineral properties of date palm (Phoenix dactylifera l.)‎

الملخص EN

This study was conducted during the two growing seasons (2018 and 2019) in Date Palm Trees Station-Al-Hussinya District-Horticulture and, Department of Forestry, Ministry of Agriculture, Karbala Governorate.

Two cultivars of date palm trees Zahdi and Khistawi were studied.

The 27 palm trees for each cultivars were randomly selected, homogeneous in vegetative growth and similar in size and shape.

The results showed that the Zahdi cultivar recorded a significant increase in the content of chlorophyll and proline which reached 0.

939 mg.

g-1 and 12.

854.

g-1, respectively.

The Khistawi cultivar recorded a significant difference in the carbohydrate content of leaf which reached 9.

564 μg.

g-1 compared to Zahdi cultivar.

The results were also showed that superiority of the concentration was 1 g.

L-1.

palm -1 in all studied characteristics.

The study showed that in the concentration of 2 g.

L-1.

Palm-1 of disper osmotic had significant difference in the most of studied characteristics.

Bilateral and triple inequalities have a significant moral effect in all studied characteristics.
