This study was carried out during two consecutive seasons (2015 and 2016)
on Sewy date palm cultivar grown in new reclaimed sandy soil at private orchard
located at Al Assiuty valley, Assuit, Egypt. The effect of spraying algae extract,
boron and silicon nutrients each alone or their combination on some vegetative
growth characteristics, yield and some physical and chemical fruit traits were
studied. The results showed that spraying algae extract, boron and silicon was
very effective on enhancing vegetative growth characteristics, yield as will as
some physical and chemical fruit properties. The promotion increased with increasing
the concentration of algae extract and their combinations. In general, the
best results of this study were recorded when using algae extract 0.3% + Boron
0.05% +Silicon 0.1% compared with the other investigated treatments.
