Using Anti-Stress Substances and Zinc Spray Under Phosphoric Acid Fertigation to Grown Under Salinity Stress of Sunflower Plant (Helianthus Annuus L.)
Year: 2021
Type: article
Abstract: Two field experiments were conducted on saline clay soil in a split-split-plot design with four replicates. The main plots were arranged to study the effect of phosphoric acid applied with irrigation water ( without, 6 L ha-1 and 12 L ha-1) where subplots were occupied towith or without the zinc spray Zn (at 13% chelated on EDTA), While the sub- subplots were occupied to anti-stress foliar which included Salicylic acid SA (foliar spraying of 0.01 mM), foliar spraying of calcium (at 10% chelated on EDTA) and Salicylic acid with calcium (foliar spraying of 0.01mM with foliar spraying of calcium at 10% chelated on EDTA). Where the interaction between these treatments showed that using phosphoric acid (12 L ha-1) acid with zinc spray (at 13% chelated on EDTA) and spraying both salicylic acid (0.01 mM) and calcium (at 10% chelated on EDTA) together showed an effective effect on increasing growth, the yield of grains, oil content and salinity tolerance by reducing the concentration of sodium and chloride in the sunflower plant.
