| Abstract | ||||
| The worsening water crisis in Egypt,aggravated by climate change, has necessitated the exploration of innovative strategies by agricultural scientists. These efforts aim to enhance productivity and optimize of this study was to evaluate the growth, yield, water-use efficiency and grain quality of the Giza 179 rice cultivar under different irrigation treatment,supplemented with anti-transpirants application and amino acids, in order to improve tolerance to water deficiency. A strip-plot experimental design with three replications was utilized for this study.Three irrigation treatments were applied in the vertical plots of 100% AOWU, 90% AOWU,and 80%AOWU. Horizontal plots represented anti-transpirants spray treatments:Control(without spraying), Kaolin, Amino acids and Kaolin+ amino acids.The study demonstrated a significant positive correlation between growth, grain yield and its attributes under well-watered conditions 100% AOWU and moderately reduced irrigation 90% AOWU in compared to the reduced water treatment 80% AOWU. Furthermore, the combination of anti-transpirants spray and amino acid treatment(Kaolin+ amino acids)led to enhanced growth and grain yield compared to the other treatments.Meanwhile, the A1 treatment required the highest amount of irrigation water, and the 80% AOWU treatment utilized the least amount. The 90% AOWU treatment exhibited superior water use efficiency compared to the other treatments. The combined application of kaolin and amino acids and amount irrigation 90% AOWU irrigation level resulted in the highest water use efficiency. Based on the results, the Kaolin+ amino acids and 90%AOWU irrigation regime were identified as the most effective in optimizing growth, yield, grain quality, and water use efficiency of the Giza 179 rice cultivar. | ||||
