Impact of spraying algae extract, boron and silicon nutrients on growth and fruiting of sewy date palm under new reclaimed soils

Abstract EN

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.
