The present study was carried out at a private orchard , in Abu-Al-Khaseeb region –Basrah, during the season of 2008 .The aim was to investigate the effect of bunches bagging by brown papar and spraying of liquorice extract at three concentrations of ( 0 , 5 , 8 ) g l−1,Spraying the trees was done 50 days from Pollination , The study included the interaction effect of both factors on some Physical and Chemical Characterizes of two date palm cultivars ( Sayer and Hillawi ) , The results were summarized as follows: The treatments of bagging bunches, spraying with 8 g l−1 liquorice exteact , and Hillawi cultivar increased bunch weight significantly, whereas the interaction effect of spraying bagging bunches at concentrations of 8 g l−1 and the treatment of bagging bunches of Hillawi cultivar increased bunch weight significantly as compared with the other interaction treatments, The treatment of bagging bunches significantly increased fruit weight significantly, while the treatment of spraying with 8 g l−1 liquorice extract increased fruit weight significantly , The treatment of bagging bunches, treatment of spraying with 8 g l−1 liquorice extract and treatment of Sayer cultivar increased total soluble solids significantly, The interaction effect between the factors were spraying bagging bunches with 8 g l−1 liquorice extract significantly increased the total soluble solids as compared with other treatments,while the treatment of bagging bunches and Hillawi cultivar significantly decreased protein and tannin content,However , the treatment of spraying liquorice extract with 5 g l−1 decreased Tannin content significantly compared with other treatments .
