Introduction: Many studies have been conducted on irrigation of upland crops with reclaimed wastewater while there have been a few reports about wastewater reuse for paddies. The majority of irrigation water requirement of paddy field in Bandargaz region (Iran) during the dry season within the last 12 years is dependent on effluent of treatment plant. Accordingly, different water parameters and 12 irrigation water quality indexes and economical- environmental filed management factor (fertilizer application rate) and crop growth and yield were studied in freshwater (FW) and wastewater (WW) filelds. Explanation: Unexpectedly, wastewater and freshwater salinity was less and more than the threshold salinity of paddy (2.0 dS.m-1), respectively and due to the high concentration of chlorine, FW is not suitable for irrigation. Based on almost all of indices and standards for assessing irrigation water quality, WW was significantly better than FW. Conclusion: The average concentration of heavy metals in both FW and WW samples were in the order of Cr˂Cd˂Pb˂Ni. However, results showed that concentration of heavy metals in WW was significantly more than FW. Nevertheless, these were below maximum allowable based on international standards and guidelines. The average nitrogen concentration in the reclaimed wastewater was 11.2 mg.lit-1 that was more than the required nitrogen concentration (7 mg.lit-1). So, a dilution strategy could be adopted when reclaimed water is used. No significant difference was observed in two type farms based on plant height, spike length, and 1000-seed weight, but this factor was significantly effective on seed per spike and seed yield so that they were higher in WW irrigated farms by 12.4 and 10 percent, respectively.

The groundwater is considered as essential resources for Irrigation in Misurata city, this type of Irrigation suffered to some problems affecting their quality. The aim of this study was to evaluate, a physiochemical and biological parameters of wells water in Misurata Area during the period between November 2016 to December 2018. The area of study about 70 Km distance between Tawarq and Eldafina was divided into eight lines per appendicular to sea cost. Five water sample were taken for each line, in which the distance about 20 Km between each line. The pH, SO4, HCO3, Ca, and D.O were within the permissible levels a according to FAO standard as well as, SAR, RSC, SSP were acceptable while EC, TDS, Cl-, K+ and Mg++, were higher than the standard, moreover, the temperature, was normal in all the samples. The heavy metals values of Fe, Mn, Zn and Cu were within the standard. In general, the results showed that high values of EC, TDS, Cl-, and Mg++ were the main reasons which lead to the deterioration of water irrigation. Therefore, the water was inadequate for agricultural purpose without any treatment such as desalination to reduce the salinity, Also the results of microbiologic analysis showed a contamination in most sample.

In order to provide the real-time monitoring for identifying the sources of pollution and improving the irrigation water quality management, the integration of continuous automatic sampling techniques and cloud technologies is essential. In this study, we have established an automatic real-time monitoring system for improving the irrigation water quality management, especially for heavy metals such as Cd, Pb, Cu, Ni, Zn, and Cr. As a part of this work, we have first provided several examples on the basic water quality parameters (e.g., pH and electrical conductance) to demonstrate the capacity of data correction by the smart monitoring system, and then evaluated the trend and variance of water quality parameters for different types of monitoring stations. By doing so, the threshold (to initiate early warming) of different water quality parameters could be dynamically determined by the system, and the authorities could be immediately notified for follow-up actions. We have also provided and discussed the representative results from the real-time automatic monitoring system of heavy metals from different monitoring stations. Finally, we have illustrated the implications of the developed smart monitoring system for ensuring the safety of irrigation water in the near future, including integration with automatic sampling for establishing information exchange platform, estimating fluxes of heavy metals to paddy fields, and combining with green technologies for nonpoint source pollution control.

Malir river, which is passing through industrial area of mega city Karachi is assessed for the suitability of its water for irrigation purposes. It was found that the concentration of studied metals is a function of position and season. Most of the pollutants are within the limits provided by national and international standards however, nickel was above the allowable limit for irrigation water quality (1000 μg/L) which is probably attributed to the discharge of effluent from vegetable-ghee manufacturing factories working in the vicinity. The overall suitability of Malir river based on EC, TDS and SAR is ranked’Permissible’ for irrigation.

A pots experiment was conducted at the Department of Biology/College of Education for Girls/University of Anbar during Autumn season of 2018-2019 to study the effect of the salinity irrigation water and spray by humic acid in some of morphological, physiological, growth and yield traits of wheat cv. IPa. The experiment was randomized complete block design (RCBD) with three replications. The first factor was assigned for irrigation by saline water at four level (S0, S1, S2 and S3), while the second factor was the foliar spraying of humic acid in three level (0.0, 1.0 and 1.5 g l-1). The results showed that there was significant reduction in plant height, vegetative dry weight, biological yield and chlorophyll leaves content when the plants were irrigated by saline water approached to 41.09 cm, 0.747 g, 0.849 g plant-1 and 38.67 SPAD, respectively at salinity level of 8.3 ds m-1 compared with the plants which irrigated by fresh water. The total carbohydrates were significantly decreased at the treatment of 8.3 ds m-1 reached 18.71 mg g-1. Spray levels humic acid achieved a significant increase in plant height, dry weight of the vegetative part, biological yield and chlorophyll leaves content sprayed at 1.0 and 1.5 g l-1 compared to no sprayed. Nitrogen concentration was significantly increased, while both phosphorus and potassium were decreased in the vegetative parts of wheat as the salinity of irrigation water increased. However, the increase of humic acid levels led to significant increasing in nitrogen, phosphorus and potassium concentration.
