Abstract
Organic fertilizer can be viewed to diminish the negative effect of saltiness on the plant.
Foliar application of yeast (4 g l-1
) and algae (4 ml l-1
) extracts on Hillawi offshoots,
watered with salt or freshwater examined. The outcomes demonstrated that yeast
extracts improved both the hormone levels and the date palm biochemical reactions.
Salinity reduced all examined growth parameters (leaf area, plant height, and leaves
number). Likewise, chlorophyll content in leaves decreased. Organic fertilizers
improved date palm growth. Yeast application increased chlorophyll content, organic
solutes, and substances growth included indole-3-acetic acid, zeatin, and gibberellin.
However, the yeast extracts increased amino acids and ascorbic acid. The organic
fertilizer lowered the accumulation of sodium in the leaf. It increased uptake of
potassium, bringing about a higher K+
/Na+
ratio. Improving plant development under
saltiness conditions was identified with an enhancement in the content of amino acids
and carbohydrate content. The use of yeast extract could induce the recovery of the
plant exposed to salinity. Organic fertilizers (yeast and seaweed extracts), which are
economically and environmentally friendly, can be recommended to farmers for
alleviating salinity.
