“…[18] showed that the water use efficiency ranged between 0.77 gm of cereals per kg of water for tall and late-growing varieties and 1.32 gm of cereals / kg of water for short and early varieties. Irrigation management strategies help to increase the area of the irrigated area, which in turn increases the productivity of the crop per unit area [19].…”

This experiment was carried out using the RCBD randomized complete block design in the Yusufiya district in Baghdad governorate during the agricultural season 2020/2021. The experiment included three spraying levels of seaweed extract of 2,4,8 ml L−1 and three levels of depletion of available water 25,50,75%, with three replicates for each treatment. Some plant tests and some water calculations were conducted, as the results indicated that there were significant differences between spray levels of marine algae extract in plant height, number of branches, leaf surface area, grain yield and biological yield. The spray level of 8 ml L−1 exceeded the levels of 2 and 4 ml L−1. It was also found that treatment 25% was significantly superior according to the different levels of depletion of the available water, as the treatment and for all the studied traits, and there was a significant superiority for the water consumption according to the level of spraying and the level of depletion, and the values ranged from 548.5 to the depletion treatment 25% and at a seaweed extract level of 8 ml L−1 to 404.5 for 75% depletion treatment and at a seaweed extract level of 2 ml L−1, As for the productivity of crop and field water, its values ranged from 1.16 and 1.54 kg m3, respectively, for 50% depletion treatment of the available water and spray level of 8 ml L−1 to 0.87 and 1.13 kg m 3 respectively, for 75% depletion treatment of available water and spray level of 2 ml L−1.

In recent decades, numerous studies have examined the effects of climate change on the responses of plants. These studies have primarily examined the effects of solitary stress on plants, neglecting the simultaneous effects of mixed stress, which are anticipated to transpire frequently as a result of the extreme climatic fluctuations. Therefore, this study investigated the impact of applied chitosan on boosting the resistance responses of peanuts to alkali and mixed drought-alkali stresses. Peanuts were grown in mid-alkaline soil and irrigated with full irrigation water requirements (100%IR), represented alkali condition (100% IR × alkali soil) and stress conditions (70% IR × alkali soil—represented mixed drought-alkali conditions). Additionally, the plants were either untreated or treated with foliar chitosan. The study evaluated various plant physio-chemical characteristics, including element contents (leaves and roots), seed yield, and irrigation water use efficiency (IWUE). Plants that experienced solitary alkali stress were found to be more vulnerable. However, chitosan applications were effective for reducing (soil pH and sodium absorption), alongside promoting examined physio-chemical measurements, yield traits, and IWUE. Importantly, when chitosan was applied under alkali conditions, the accumulations of (phosphorus, calcium, iron, manganese, zinc, and copper) in leaves and roots were maximized. Under mixed drought-alkali stresses, the results revealed a reduction in yield, reaching about 5.1 and 5.8% lower than under (100% IR × alkali), in the first and second seasons, respectively. Interestingly, treated plants under mixed drought-alkali stresses with chitosan recorded highest values of relative water content, proline, yield, IWUE, and nutrient uptake of (nitrogen, potassium, and magnesium) as well as the lowest sodium content in leaves and roots. Enhances the accumulation of (N, K, and Mg) instead of (phosphorus, calcium, iron, manganese, zinc, and copper) was the primary plant response to chitosan applications, which averted severe damage caused by mixed drought-alkali conditions, over time. These findings provide a framework of the nutrient homeostasis changes induced by chitosan under mixed stresses. Based on the findings, it is recommended under mixed drought-alkali conditions to treat plants with chitosan. This approach offers a promising perspective for achieving optimal yield with reduced water usage.
