Organic fertilizer modulates IAA and ABA levels and biochemical reactions of date palm Phoenix dactylifera L. Hillawi cultivar under salinity conditions

Organic fertilizercan 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. Salinityreduced all examined growth parameters (leaf area, plant height, and leaves number). Likewise, chlorophyll content in leaves decreased. Organicfertilizersimproved 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 fertilizerlowered the accumulation of sodiumin 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 contentof amino acids and carbohydrate content. The use of yeast extract couldinduce the recovery of the plantexposed to salinity. Organic fertilizers(yeast andseaweed extracts), which are economically and environmentally friendly, can be recommended to farmers for alleviating salinity.
