“…Meanwhile, Pardo et al (2022) reported that the barley yield was decreased over three consecutive years due to deficit irrigation. In addition, Yerli et al (2023) found that reducing the irrigation regime to 67% of full irrigation resulted in a 26% decrease in dry biomass of maize.…”

“…Samarah et al (2020) stated that the higher grain yield under irrigation with TW was due to lower stomatal resistance and higher photosynthetic rate. Some researchers showed that irrigation with treated and untreated wastewater increased the grain yield compared with freshwater (Ait‐Mouheb et al, 2022; Samarah et al, 2020; Yerli et al, 2023). According to the results of Hussain et al (2022), higher salinity levels in the IW led to a remarkable reduction in the barley yield parameters.…”

This study examines the effects of three irrigation regimes with a combination of saline water and treated wastewater on the accumulation of heavy metals in barley grains. A field experiment was designed as a split‐split plot arrangement in a randomized complete block design, in which treatments were different irrigation regimes (50, 70 and 100% full irrigation) and irrigation water types (saline water (SW), treated wastewater (TW), mixed water resources (MWR) and alternative irrigation (AI)). After cultivation and harvesting of the barley crop, the grain yield, 1000‐grain weight and contents of heavy metals in the grains were measured. The grain yield was enhanced by TW alone, MWR and AI to 12.8, 5 and 9.5% under 70%‐deficit irrigation, and 58.3, 21.7 and 8.7% under full irrigation, respectively. Based on the guidelines for safe limits of heavy metals in edible plants and livestock feed, the barley grains were safe for livestock and toxic for humans. The trend of heavy metal contents in the grains was Fe>Zn>Pb>Cu≥Cr>Cd. Irrigation with saline water compared to treated wastewater increased Fe, Cu, Zn, Pb, Cd and Cr contents in the grains to 11.75, 10.97, 5.22, 19.15, 3.45 and 9.21%, respectively. The amounts of toxic elements of Cd and Pb were maximized by using MWR, while the Cr content in the grain was maximized by using AI. There were no significant difference in the metal uptake by the grains among all irrigation regimes in any irrigation water resource. However, compared to the other irrigation regimes, the full irrigation resulted in lower Zn, Cu and Cd contents, while the 50%‐deficit irrigation led to lower Pb and Cr contents in the grains. Therefore, irrigation with TW is recommended based on the grain yield, while AI is suggested due to lower Cu, Pb and Cd contents in the grain, and MWR is recommended due to lower Cr content. Furthermore, full and 50%‐deficit irrigation regimes are recommended to respectively maximize grain yield and minimize the toxic metal contents in the grain.

“…This is in agreement with Zhang, Q., et al (2022b) that efficiency gains in maize yield from no-till can also occur under a combination of mulch and appropriate precipitation conditions. yield, plant height, provide additional contributions to explain yield differences, as evidenced by their significant correlation (Yerli et al, 2023). Interestingly, CP was significantly and negatively correlated with yield, plant height, and LAI.…”

To cope with the change of precipitation pattern, we explored the effects of conservation tillage and precipitation variability on soil moisture status and silage maize productivity, seeking solutions to improve the yield and quality of maize in the karst areas of China. In this study, precipitation variability and conservation tillage were jointly analyzed by precipitation levels (normal precipitation, 30% lower and 30% greater than normal precipitation), tillage methods (conventional tillage and no-tillage) and cover crop mulching (mulching and no mulching). It was found that no tillage (NT) increased the maize yield by 12.85% compared with the conventional tillage (CT) treatments. Above-normal precipitation treatments did not significantly increase biomass and soil water content across different fertility stages, but below-normal precipitation treatments reduced maize yield, crude protein (CP) content and soil water content at all soil levels. CT treatment significantly increased soil water content in the tillage layer (0–40 cm), but NT treatment significantly increased dry matter yield, plant height and CP content at harvest by 10.99, 3.41, 5.62%. Cover crop mulching significantly increased maize yield by 8.26% and soil moisture content at the seedling stage in 0–40 cm soil by 2.76 and 2.52%. The three-way interaction effects involving precipitation levels, tillage methods and cover crop mulching were significant for maize yield, CP content and soil water content (p < 0.05). In addition, this study found that soil water content was positively correlated with crude protein content of maize (p < 0.05). In conclusion, this study concluded that a combination of NT and cover crop mulching should be used to mitigate maize production risks caused by precipitation variability in the karst areas.

“…It also agrees with the finding of Balengayabo et al (2022), which stated that using treated wastewater to irrigate crops increased crop yield by 30 -40 %. Yerli et al (2023), stated that under-treated wastewater irrigation, the yield production of maize was increased, and attributed this rise to the improvement in the soil's physical characteristics, which enhanced nutrient uptake.…”

With increasing global population, the gap between the supply and demand for water is widening and poses a threat to human existence. In the face of water scarcity, urban wastewater is increasing in its attention as an alternate water source for crop production. However, several challenges such as toxicity hazards, salinity build-up and health concerns have been identified with the use of wastewater in agriculture. There are several technological solutions that can help ameliorate or lower the level of contamination associated with using wastewater for irrigation. This paper explores the use of some irrigation technologies to abate the toxicity and health concerns associated with wastewater irrigation. The paper identifies some decision parameters for the selection of identified irrigation technologies and subjects them to multi-criteria decision analysis (MCDA) to rank them based on the level of exposure of the crop and irrigator/field worker to contamination among other relevant criteria. This paper validates that limiting the contact of the wastewater with the edible parts of the crop, especially for leafy vegetables, can minimize contamination to the crop and field workers. Though not totally without constraints, the identified irrigation methods present prospects for a cleaner and more sustainable production with regard to wastewater usage in agriculture. Sub-surface drip irrigation systems were identified as the best irrigation system for filtered and treated wastewater followed by surface drip and pitcher irrigation. Irrigators can fall back on some of these identified methods for wastewater application for sustainable crop production and maximized food safety.
