Abstract
ABSTRACT : This study was conducted in Al-mahwel date palm research station / Minstary of Agriculture during two successive seasons 2011and 2012on date palm Sultani c.v at(six years old, to investigate the effect of Salicylic Acid (S0=0, S1=150 and S2=300) ppm, drip irrigation (IR1=16L.hr-1and IR2=32L.hr-1) and chemical fertilizers treatment (F1) and applied mycohrriza (F2) on chemical and physical properties of fruit. Results of this study can be summarized as follows:- Drip irrigation of treatment (IR2) had a significant effect on the fruit,size ,brunch weight and %TSS, during the first season, and fruit size,fruit weight,brunch weight,total and reducing sugars, TSS% , during the second season.The chemical fertilizers treatment (F1) significantly influenced fruit weight, bunch weight and total soluble solid percentage during the first season , and fruit size, bunch weight and total soluble solid percentage during the second season , the mycohrriza treatment (F2) resulted in a effect in the average of most studied characteristicis as compared with control treatment during both seasons. Treatment of S had asignificant effect on the average of fruit size, fruit weight ,bunch weight during the first season,furthermore. Interaction of(IR1F1S1)had significant effect on the average of fruit size , fruit weight ,bunch weight , total and reducing sugars, TSS%, during the first season.
