“…Although the use of wastewater in irrigation brings high yield and quality, the risks they create should not be ignored. Wastewaters contain dissolved salts, heavy metals, and some other harmful chemicals and pathogens apart from nutrients (Dogan Demir and Sahin, 2019;Cakmakci and Sahin, 2021). This situation can reveal many negativities in soil quality, crop production, and live health.…”

Increasing pressure on water resources in the world has revealed the necessity of using marginal water resources in irrigation. With the use of wastewater, which is one of the marginal water resources, the pressure on freshwater resources is alleviated, the discharge problems of wastewater are solved, and soil and crop productivity increase with the high nutritive effect of wastewater. However, salinity, heavy metals, some harmful chemicals, and the pathogen risks of wastewater should not be ignored. In this context, in this study, the effluent of the wastewater treatment plant located in the central Edremit district of Van province was evaluated in terms of usability in irrigation. Samples were taken from treated wastewater during the vegetation period in 2020 and 2021 and pH, EC, cation and anions, micro elements and heavy metal, total nitrogen and phosphorus, total suspended solids, chemical oxygen demand, biological oxygen demand, fecal coliform, percent sodium, sodium adsorption rate, residual sodium carbonate and Langelier saturation index were determined by analysis and calculations. As a result of the study, the treated wastewater does not pose a risk in terms of pH, EC, cation and anions, micro elements and heavy metal, total suspended solids, percent sodium, sodium adsorption rate, residual sodium carbonate, langelier saturation index and fecal coliform, but attention should be paid to the total nitrogen and phosphorus, chemical and biological oxygen demand contents. It was concluded that the treated wastewater is in compliance with national and international standards, and there is no harm in its use in irrigation and thus treated wastewater can be recommended as a reliable water source for irrigation in the semi-arid province of Van/Edremit. However, in order to ensure safe and sustainable management in irrigation with wastewater, it is necessary to monitor water quality and make necessary inspections of soil, crop and irrigation systems.

“…vapour pressure deficit) are closely linked in transitional soil moisture regimes (ranging from dry to wet soil conditions), the identification of which is critical for quantifying these relationships under different soil moisture conditions. Demir and Sahin (2020) stated that drip irrigation over other irrigation methods improves efficiency in use of water and nutrients since it decreases water and nutrient loss through deep percolation, and declines total water requirements with more controlled irrigation. Cakmakci and Sahin (2021) found that the subsurface drip method saved 20.7 and 49% more irrigation water than the surface drip and furrow methods, respectively under fully irrigated conditions.…”

An experimental field was carried out during the growing season of 2019/20 and 2020/21 at The Experimental Farm, Fac. of Agriculture, Assiut, Egypt (27 12-16.67= N latitude and 31 09-36.86= E longitude) in order to evaluate the change in soil moisture retention and wheat plant response to different irrigation practices as well as their performances and water productivity. The tested irrigation practices (border, furrow, alternative furrow, gated pipe and surface drip) were arranged as factorial in a completely randomized design with three replicates. The soil moisture retention decreased clearly with soil depth for all irrigation practices through both seasons. On average basis of both seasons, the soil water retained in 60 cm soil depth was 12.36, 12.17, 11.99, 11.91 and 11.75 cm water depth for basin, furrow, alternative furrow, gated pipe and drip irrigation practices, respectively. It could be arranged the amount of retained water in descending order of basin > furrow > alternative furrow > gated pipe > drip irrigation practices. In general, it was noticed that the retained water in the top layer (0 -30 cm) was higher than that in sub layer (30-60 cm). On average basis of both seasons, the relative increases in soil water retention in 60 cm soil depth were 3.79, 3.60, 2.00 and 1.40% for basin, furrow, alternative furrow and gated pipe, respectively compared to drip irrigation practice. The irrigation performance indices of gated pipe and drip irrigation were utmost the other irrigation practices. Water application efficiency, the non-beneficial water consumption, water storage efficiency and distribution uniformity was 84.15 and 85.29%, 18.85 and 17.25%, 58.04 and 56.15% and 90.68 and 90.90 for gated pipe and drip irrigation practices, respectively. The highest wheat grain and straw yield were attained at gated pipe and drip irrigation practices since grain yield was 3164.0 and 3113.0 kg/ fed. and straw yield was 3691.5 and 3646.0 kg/fed., respectively. It might be concluded that applying more irrigation water than can be stored in the top 60 cm of the soil profile will result in inefficient utilization of this water by winter wheat. Selection of a suitable irrigation method would depend on the specific conditions of water resources, crop types and management requirements.

Irrigation with recycled domestic wastewater has been known to obtain positive effects on improving soil fertility, but it may also become a risk factor in case of causing an increase in soil salinity and/or heavy metal concentration of soil. No-tillage can retain soil moisture, helping to reduce irrigation water necessity, and thus lower amounts of heavy metals and salts are added to soil under wastewater irrigation conditions. The objective of this study was to analyze the effects of wastewater irrigation at different levels of on silage maize cultivation under conventional tillage and no-tillage conditions by comparing to full irrigation with fresh water. The two-year experiment was planned according to the split-plots design in the random blocks with three replications. The results indicated that full irrigation with wastewater increased soil salinity, organic matter content, total nitrogen, plant available phosphous, exchangeable cations, exchangeable sodium percentage and soil essential and non-essential heavy metal contents, but decreased soil pH and lime content. Increasing rates in organic matter content, total nitrogen, plant available phosphorus and exchangeable potassium were higher, but in electrical conductivity, and heavy metal accumulation were lower in soil under no-tillage as compared to conventional tillage. Contamination and enrichment factors and geographic accumulation index showed that non-essential heavy metal contamination due to cadmium and nickel, increased in full irrigation with wastewater. Irrigation with wastewater also increased heavy metal accumulation in silage maize. No-tillage can be a recommendable water management practice considering that the risks of soil salinity and heavy metal accumulation can be reduced and that soil fertility can be increased. Also, in reducing the risk of accumulation of cadmium and nickel in soil, 33% deficit irrigation with wastewater can make no-tillage more available.
