Developing new tools for using low-quality irrigation waters is vital for the sustainability of irrigated agriculture and minimizing salt accumulation. Therefore, the present study focused on the interactive influence of irrigation treatments (magnetized (MT) and non-magnetized (NMT)) and water salinities (0.38, 1.5, 4.5, and 7.0?dSm?1) on soil salinity, water use efficiency, yield and morpho-physiological changes of Balk?z bean. A pot experiment was conducted in a randomized complete block design with three replications under the rain shelter condition. Irrigation water MT treatment increased fresh bean yield, water use efficiency (WUE) and irrigation water use efficiency (IWUE) by 21.35, 23.00 and 14.8%, respectively, while saturated soil salinity was reduced by 20%, compared to NMT treatments. The leaf area, stomata, and leaf succulence in green beans in the MT treatment significantly increased by 13.4, 23.9, and 3.3% compared with those in the NMT treatment. Stems of the bean crops were more sensitive to salinity stress followed by roots and leaves. The study revealed that irrigation with magnetically treated water manages salinity related yield loss through increased morphological features as well as osmotic and stomatal adjustments. In addition, the bean crops showed an ability to protect water in tissue against salinity toxicity up to 5.24?dSm?1 soil salinity level under magnetized saline water conditions. Finally, irrigation with magnetically treated 0.38?dSm?1 irrigation water can be recommended due to providing a higher yield, WUE, IWUE, and sustainable production under saline irrigation in water scarcity regions.
相似文献The adverse effects of shallow-saline groundwater may vary among crucial growth stages of crops by decreasing crop growth and productivity. The present study aimed to assess the germination and seedling growth ability of wheat seeds grown in four different (0.38, 2.0, 4.0, and 8.0 dSm?1) groundwater salinities (GWS) and three (30, 55, and 80?cm) groundwater depths (GWD) condition. To achieve this aim, wheat crops were grown in drainable lysimeters under rain shelter conditions until the maturity stage, and then wheat seeds were harvested from various saline groundwater conditions. Afterward, wheat seeds were germinated to identify the performance of germination and seedling growth attributes. Response surface methodology (RSM) was used to determine the optimal growing wheat seeds condition, which had high early seedling growth performance. The results showed that the seedling growth performance of wheat seeds increased with increasing GWDs, while decreased with increasing GWSs. Based on the RSM findings, we suggest that GWD and GWS should be at least 42?cm and at most 5.46 dSm?1, respectively, for sustainable higher wheat yield and seed quality. Finally, this study could provide considerable information for selecting strong and healthy wheat seeds grown under shallow saline groundwater conditions.
