AbstractThe study has been conducted in a private orchard of Abu Al-Khasib district in Basrah governorate -Iraq. To investigate the effect of some seaweed extracts and nutritional solutions in the physical properties of date palm trees. Trees of two date palm cultivars, Bream and Hillawi, were sprayed with two seaweed extracts, Phlygreen Mira (3.5) ml / L and Alga AL-Zuhoor (3) ml / L , as well as bio nutrition Callmax with a concentration of (4.5) ml / L.
The trees under the study were divided into two groups. The first group was sprayed with the studied solutions on the leaves and the spraying continued on the fruits of the same trees to the end of the chimri stage, while the second group was sprayed only on the fruits until the end of the chimri stage. The results of this study showed that:
The spray by the seaweed extract phylgreen Mira improved physical properties of date palm fruits except seed weight for both cultivars, which fruit weight was increased from 5.12 g in control to 6.85 gm for Bream cultivar and from 5.43 g in control to 6.33 g for Hillawi cultivar. The highest value of pulp weight and fruit volume was found in Bream cultivar fruit which was 5.73 g and 6.33 cm3 respectively. Also, sprayed with seaweed extract Phylgreen Mira on leaves and fruits led to increase fruit lenght and diameter, which were 2.97 and 2.13 cm for Bream cultivar and 3.44 and 2.11 for Hillawi cultivar respectively.
