| The anticipated consequences of climate change include adverse effects on numerous agricultural ecosystems and diminished water resources, which are projected to result in a decline in the yield of significant food crops such as wheat. Hence, the prioritization of crop research is the development of crop types capable of sustaining or enhancing yields while minimizing water usage. Hence, it is imperative to employ a technique aimed at mitigating the plant's water loss by transpiration, with one such approach being the utilization of antitranspirants. The current investigation involved a field in a split split-plot design experiment aimed at comprehending the effects of antitranspirants on the physiological and yield attributes of wheat cultivars (Triticum aestivum L.) under varying irrigation levels. The present investigation encompassed three different irrigation treatments, namely 100%, 80%, and 60% of the recommended irrigation levels, applied at rates of 5476, 4381, and 3285 m3 ha-1, respectively. Additionally, three distinct wheat cultivars, namely Sids 14, Giza 171, and Sakha 95, were included in the study. Furthermore, four treatments consisting of kaolin at a concentration of 5%, potassium sulphate at a concentration of 200 mg L-1, paraffine at a concentration of 6%, and a control treatment involving water spray were also incorporated. The physiological parameters that were assessed included total chlorophyll, membrane stability index, relative water content, stomatal density, and transpiration intensity. The growth and yield parameters were documented subsequent to the crop's harvest. The findings of the study indicate that exposing wheat cultivars to prescribed irrigation resulted in notable enhancements in the examined feature, as compared to alternative irrigation treatments. The application of antitranspirants resulted in notable enhancements in the observed characteristics across all cultivars when subjected to irrigation intensities of 80% and 100%. Furthermore, the three wheat cultivars exhibited varying responses under the three irrigation regimens, as well as in the presence or absence of foliar spray application of antitranspirants. | ||||
