Abstract
Abstract
The date palm cv. Braim, is one of the commercial Iraqi dates, that are consumed at khalal, rutab and tamar stages. Therefore, this study was conducted with the aim of decreasing fruit drop, improving physical and chemical features, increasing yield and possibility of extending shelf life of the fruits. The trial has been implemented on 28 years old date palms cv. Braim for the period from April to October 2023 at Horticulture Research Station in Latifiya, 45 km south of Baghdad. Three factors were used in this study, including spray three concentration of NAA (assay 90%) till run off, which include (0,50 and 100 mg L-1), The second factor include three concentrations of K2SO4 (0, 15 and 20g L-1), spraying was done for NAA and K2SO4 three times after pollination, i.e. during hababuk stage, beginning of Kamri stage and at the beginning of khalal stage. The third factor included, spray of licorice root extract at two concentrations (0 and 10 g L-1), spray was done after 2,8 and 14 weeks after pollination. Results showed that the three factors increased fruit weight, bunch weight, yield and reducing fruit drop especially in high concentration, on the other hand, NAA spray at (50 and 100 mg L-1) delaying fruit ripening, reducing total sugars and TSS, while spray potassium and licorice root extract, at concentration (20 and 10 g L-1) respectively, increasing total sugars and TSS consequently increasing fruit ripening.
