Abstract
Present study has been conducted during the growing season of 2016 at Al-Bida Date palm Station The study evaluate the effect of the irrigation quantity of water (0, 70 and 140) Liter-1/date palm tree-1/ week-1 with spraying the tree with bio-growth promoter 'Delzi' (2 and 4 ml/L-1) on some physical, chemical, and physiological characteristic of fruits and leaves of two date palm cultivars Shwethee and Khadrawi. Studies also carry out the effect of various treatments on total productivity of two cultivars under investigation. The cultivar Shwethee significantly superior in fruit weight fruit size, , bunch weight and The cultivar Shwethee recorded significant decreased in rate of total soluble solid comprise, comparative with cultivar Khardawi The irrigation treatment (140 L/tree-1/week-1) significantly superior on the two control's treatments (distilled water). Whereas the heights fruit physical (fruit weight, fruit size, the percentage of soluble solid comprise comparative with control and 70L tree/week treatments. The findings revealed that the spraying with Bio- growth promoter (4ml/L-1) significantly superior on other treatments. This treatment gave rise the heights fruit physical characteristics that included (fruit weight and fruit size, the percentage of soluble solid comprise bunch weight comparative with other treatments (control and 2 ml/L-1). The results shows that there is an prominent impact between the interactions of Shwethee cultivar and the irrigation treatment (140 L/tree-1/ week-1), whereas it gave rise the highest significantly superior in fruit weight and flesh, fruit size, bunch Whereas the results also revealed that the interactions of Khadhraawi cultivar and the irrigation treatment (140 L/tree-1/ week-1) gave rise the significantly increased in percentage of total The results shows that there is an prominent impact between the interactions of Shwethee cultivar and spraying with bio-growth promoter treatment (4ml/L-1), whereas it gave rise the highest significantly superior in fruit weight and flesh, fruit size of bunch weight Whereas the results also revealed that the interactions of Khadhraawi cultivar and the spraying treatment (4mL/L-1) gave rise the significantly increased in total soluble comprise The dual interaction between of irrigation treatment and spraying with bio-growth promoter (140 L/tree-1/week-1+4 ml/L-1 bio-growth promoter) shows significantly increased in physical characteristic of fruits (weight of fruit, , fruit size the percentage of soluble solid comprise and bunch weight compare with other treatments The triple interaction treatments between Shwethee cultivar, irrigation treatment (140 L/tree-1/week-1) and bio-growth promoter (4 ml/L-1) significantly weight of fruit, weight of fruit , fruit size percentage of soluble solid comprise bunch weight Whereas the triple interaction treatments between Khadhaawi cultivar, irrigation treatment (140 L/tree-1/week-1) and bio-growth promoter (4 ml/L) gave rise the significantly increased total soluble.
