“…Since maize, a C4 crop, has more photosynthetic activity compared to other crops, it can metabolize high levels of N from waste water (Alkhamisi et al, 2011). As a result of different studies, it has been reported that irrigation with waste water increases the chlorophyll content (Petousi et al, 2015;Alkhamisi et al, 2017;Petousi et al, 2019;Cakmakci and Sahin, 2021;Soltani-Gerdefaramarzi et al, 2021). The decrease in chlorophyll content due to increased water stress can be explained by insufficient soil moisture limiting the uptake of N which improved chlorophyll.…”

Increasing fresh water shortage has revealed the use of waste water in agricultural irrigation, deficit irrigation approaches and integrated management of soil moisture with tillage-sowing practices. The crop productivity in the irrigated conditions is directly controlled by photosynthetic activities. Therefore, the effects of the irrigation with recycled domestic waste water at different irrigation water levels (100%, 67% and 33%), compared to full irrigated fresh water, on the chlorophyll content of silage maize and surface soil moisture in conventional tillage and direct sowing conditions were examined in the irrigation periods of two experimental years (2020 and 2021). The soil moisture was determined by 1.5% higher in direct sowing than in conventional tillage, and the chlorophyll content in full irrigation with waste water and the direct sowing was found by 4.9% and 1.9% higher than in full irrigation with fresh water and conventional tillage, respectively. However, chlorophyll content decreased by 20.7% and 34.0% at 33% and 67% deficit irrigation with waste water compared to full irrigation with waste water. The significant (p<0.01) linear correlation between the soil moisture and chlorophyll content showed that chlorophyll content can be managed with the soil moisture. It can have concluded that full irrigation with waste water in the direct sowing can be recommended with positive effects on the conservation of fresh water resources, effective managing soil moisture, thus saving irrigation water, increasing chlorophyll content and crop productivity.

The growing population in the face of water scarcity inevitably necessitates the quest for alternative sources of irrigation water, which integrates them with irrigation strategies for improved agricultural productivity to meet the Sustainable Development Goals. A three-year field experiment was conducted in 2017, 2018, and 2019 to investigate the effect of water quality (reclaimed water (RW) and clean water (CW)), irrigation techniques (subsurface drip irrigation (SDI) and furrow irrigation (FUI)), irrigation methods (full irrigation (FI) and alternate partial root-zone irrigation (APRI) (70% ETc)), and their interactions on the fresh fruit yield (FY), irrigation water use efficiency (IWUE), and nitrogen use efficiency (NUE) of tomatoes. Further, electrical conductivity (EC), pH, and organic matter (OM) of soil were evaluated. The experiments were undertaken over three growing spring seasons in a greenhouse at the Chinese Academy of Agricultural Sciences in Henan Province, China. Throughout the three years of this study, the yield, the IWUE, and the NUE values of all treatments under RW were higher than those corresponding values under CW. The trend was the same under SDI as it was under FUI. Statistical analyses revealed that there was no significant effect (P > 0.05) of water quality, irrigation technique, and irrigation methods on the soil EC, pH, and OM over the three years. In addition, the interaction between the different experimental factors over the three years of the study was not significant. In conclusion, the application of RW under SDI can result in saving CW and increasing productivity without any negative effect on the investigated soil properties. Furthermore, when RW-SDI is used in conjunction with APRI, it can result in increasing IWUE.
