“…On the contrary, Elfanssi et al (2018) found that the mean leaf area of Medicago sativa L. (alfalfa) irrigated with FW decreased, while the mean leaf area of alfalfa irrigated with treated wastewater continued to increase, indicating that irrigation with FW has a positive effect on alfalfa growth. Similarly, Ben Said et al (2017) observed that crops irrigated with FW showed better growth in both growth cycles compared to those irrigated with FW. The quality of irrigation water significantly influenced the height and leaf width of Cenchrus ciliaris (foxtail buffalo grass).…”

Currently, the convergence of climate change, population growth, and deteriorating water quality has triggered a scarcity of freshwater resources, presenting substantial hurdles for agricultural endeavors. Consequently, repurposing treated wastewater for agricultural use is gaining prominence. This strategy offers a noteworthy advantage by furnishing an alternative water source, distinct from conventional freshwater, for agricultural irrigation. The considered irrigation water categories encompass treated wastewater, sewage treated with supplementary fertilization, treated water of a specific quality, and treated water quality fortified with fertilizer. An assessment of the treated wastewater extracted from the Imzouren‐Bni Bouayach treatment facility was undertaken, encompassing scrutiny of its physical, chemical, and bacteriological attributes. This analysis yielded measurements for a range of parameters, including pH, temperature, electrical conductivity, dissolved oxygen, suspended matter, biochemical oxygen demand, chemical oxygen demand, total phosphorus, nitrate, nitrite, total coliforms, fecal coliforms, and fecal streptococci. These measurements align with acceptable thresholds for direct discharge and are following Morocco's established water quality standards tailored for irrigation. In light of the soil analysis, the soil is classified as alkaline, with a pH of 8.2, and displays low salinity, evidenced by an electrical conductivity of 2.42 mS/cm. Furthermore, the soil exhibits deficiencies in organic matter and essential nutrients, with carbon content measuring 0.84%, organic matter at 1.45%, nitrogen at 0.07%, phosphorus at 10.6 mg/L, and potassium at 56.5 mg/L. The utilization of treated wastewater for irrigation purposes bestows the crop with a dependable water supply, ensuring stability in its growth.

“…Additionally, wastewater contains many different types of pathogens that can represent a great risk for human and animal health. However, wastewater, for its richness in biodegradable organic material (carbon and nitrogen) along with macronutrients and micronutrients, may have beneficial effects on soils and crops representing a valid alternative to FW In this study, the municipal wastewater had been treated with the biological stabilization ponds that reduced the biochemical oxygen demand (BOD) and chemical oxygen demand (COD) values and pathogen load (Ben Said et al, 2017), making them more suitable and safer for irrigation purpose. Accumulation of OM in soil through irrigation with wastewater can result in an improvement of soil chemical and physical properties, with consequent positive effects on environment and plants.…”

“…Considering the raising demand of sheep and goat meat, it results necessary to find sustainable solution to improve forage cultivation in arid environment, where food, essentially dependent on the rangelands, can affect the economy of countries that otherwise will be forced to import animal proteins, worsening their economic status (Valone et al, 2002). A previous study (Ben Said et al, 2017) evaluated the possibility of reusing municipal TWW to irrigate the tetraploid C. ciliaris , demonstrating that TWW can be a sustainable option to the use of fresh water (FW) for watering this fodder species. In addition, it has been also demonstrated that when irrigated with TWW, ‘tetraploid’ plants improved their growth than plants irrigated with FW (Ben Said et al, 2016).…”

The increasing aridity exacerbated by climatic changes is leading to loss of perennial herbaceous plants Cenchrus ciliaris, an apomictic, polyploid grass used as forage in hot and dry areas, and is currently under threat for the increased scarcity of water. In this study, treated municipal wastewater (TWW) was used to irrigate two ploidy levels of C. ciliaris for two consecutive years. The objectives were (1) to assess the possibility of using unconventional water for watering C. ciliaris and (2) to identify at what extent TWW irrigation affected growth and nutritive properties of C. ciliaris that differed for polyploidy level. TWW irrigation positively affected growth and physiological plant parameters. In leaves of TWW watered C. ciliaris, the concentration of Nt, P and K significantly increased. The tetraploid C. ciliaris showed a better growth and quality than the hexaploid ones, appearing the most suitable cultivar to be irrigated with TWW for feed uses. In short, TWW can be strategically used for irrigating forage species with the double output of ameliorating soil properties, recovering degraded area and improving the nutritive values of fodder species contributing to the promotion of a green and sustainable circular economy, more in climatically under pressure developing countries.

It was concluded that the reclaimed municipal wastewater treated with biological stabilization ponds could be used to irrigate fodder due to its low biochemical oxygen demand (BOD), reduced COD, and the absence of pathogens.…”
