Agriculture and climate change are internally correlated with each other in various aspects, as climate change is the main cause of biotic and abiotic stresses The land and its agriculture are being affected by climate changes in different ways like Date palm bunch wilt and dry disorder (DBWD), the cause of which remains unknown, is among the most harmful disorders in recent years. No research has been done to identify the main factor of the physiology disorder affecting date production and quality. This research was conducted for duration of two years, 2020 and 2021 seasons on palm groves of “Saidy" afflicted with (DBWD). The experimental site was chosen to study the effect of essential nutrients application by addition of balanced amounts of macro and micro-nutrients (T1) were applied on the basis of soil and leaf analysis. as well as spraying potassium silicate at 10 mL /L water (T2) and salicylic acid at 100 ppm (T3) and the interactions between them on Date Bunch Wilt and Dry disorder (DBWD) Results declared that single and combined applications of the three treatments (T1, T2 andT3) were very effective, as it caused a decrease in the percentage of Date palm bunch Wilt and Dry disorder, and showed a remarkable promotion on bunch weight, yield as well as physical and chemical characteristics of the fruits in comparison with the control treatment (T0). The promote effects of these treatments on the investigated parameters could be arranged as follows in descending order T1, T3, and T2. The combined application of these treatments was superior than using each alone in this respect.
