Abstract
The aim of this study was to maximize yield and improve fruit quality of Zaghloul date palms by spraying GA3 (50 ppm) or Sida Film (as wetting agent, 1 cm3/1L) at three different growth stages of dates (Hababouk, Kimri and Khelal stages). Therefore, this investigation was carried out at the Fruit Orchard, Faculty of Agriculture, Assiut University in 2001 and 2002 on twenty one palms using split-plot arrangement of complete randomized block design (CRB) with 3 replicates, one palm each.  The chosen palms were pollinated with a known male palm leaving 9 bunches/palm with 8:1 leaf/bunch ratio throughout the two studied seasons.  According to the obtained results from this study, it could be concluded that all treatments with GA3 or Sida film significantly increased bunch weight and consequently yield weight/palm.  Moreover, GA3 was superior than Sida film and it was more effective at the 1st growth stage of dates (Hababouk stage).  In addition, either GA3 or Sida film resulted in significant increase in physical characters of fruits, and showed no constant effect on chemical characters of Zaghloul dates.  These results are important for economic and horticultural point view.  It could be recommended under these conditions and the resembling conditions that spraying either GA3 (50 ppm)or Sida film (1 cm3/1L) at Hababouk stage was useful to get high yield with good dates quality.
