Abstract
This investigation aims to reveal the physiological responses of two local wheat cultivars (Triticum aestivum L.) to grain yield strived under the extreme conditions of desert environments. In arid and semi-arid regions where contemporary civilization relies on agriculture, we used a Chlorophyll Fluorometer linked to the WinControl-3 software, which enabled us to monitor the health status of the plant accurately. Conventional methods of assessing the health of the crops are beneficial to endeavor, but an infusion of technology as such enables effective resource management while increasing the efficiency of monitored physiological changes. We noted that with critical modular water deficit stress during vital stages of development, there is not a marked reduction in grain yield. The yield data collected at the end of April for the BUHOTH 22 cultivar reveals that the yield for the 6-day irrigation interval was 552 g/m², resulting in a total of 1380 kg for 2500 m². The parameter of fluorescence Fv/Fm was found to be the most important marker able to differentiate the physiological state over a period of time. This parameter is significant as it raises the standard of care and management of plants and determines the optimum irrigation proviso for arid regions, improving the yield of such areas. This study highlights the link between physiological changes in the plant life cycle and grain yield under water deficiency, emphasizing the need to integrate these physiological components into agricultural management strategies. Identifying these correlations enables farmers to swiftly address challenges in their work.
