A doctoral thesis at the College of Agriculture at the University of Basrah discussed (the effect of foliar spraying with ascorbic acid and organic nutrients on some physiological and anatomical characteristics and the yield of the fruitful date palm cultivar Barhi). The thesis included the researcher (Dhafer Nasser Abboud) This study was conducted in one of the private orchards affiliated to Basra Governorate - Al-Haritha District - Al-Mashab area during the growing season 2020-2021 in order to know the effect of foliar spraying with ascorbic acid at three concentrations (0, 500, 1000) mg L-1 and the organic nutrient Youngren in three concentrations (0, 500, and 1000) , 2, 4) ml L-1 and Al-Reef Al-Extra in three concentrations (0, 500, 1000) mg L-1 in the physiological and anatomical characteristics and yield of the fruitful tissue date palm cultivar Al-Barhi, for three sprays per season (before the emergence of the pollen and after the completion of the appearance of the pollen and in chimeric stage). The current study aims to enhance the physiological performance of the fruitful tissue date palm trees of the Barhi variety, newly planted in Basra Governorate, by using ascorbic acid and some organic nutrients through which we hope to raise the efficiency of the trees, as well as physiological processes such as photosynthesis and the production of organic compounds. In light of the results of the current study, we conclude the following: The treatment of tissue date palm trees of Barhi cultivar with ascorbic acid (1000 mg L-1) and the organic nutrients Youngren and Al-Rif-Extra (4 ml L-1, 1000 mg L-1) had a role in improving most of the physical and chemical characteristics of fruits, chemical, physiological and anatomical for fruits and leaves , as well as indicators of the outcome. And the components of the materials used in the study had a positive effect on improving the quality of the fruits. In light of these results, we recommend the following, and given the high demand for textile palm cultivation, we recommend conducting similar studies on other varieties using organic nutrients with different concentrations and evaluating their positive impact on vegetative and fruitful growth indicators.
