“…To overcome this water scarcity, many countries are adopting the use of poor quality water for irrigation purposes. Studies have demonstrated that excessive salts disrupt the ionic distribution (Ankush et al 2020) and water potential equilibrium, resulting in physiological changes and reduced plant growth (Phogat et al 2010). Therefore, there is a need for the efficient use of poor quality water and balanced fertilisation to have better crop production and make effective use of the input resources.…”

The ever-growing population is driving an increase in the food demand and increasing the need for water in agriculture. Therefore, keeping food security in view, agricultural production requires the continuous improvement of irrigation prac-tices due to the global constraints on freshwater availability and increasing demand of water in the agricultural, industrial, and urban sectors (Dalin et al. 2017;Ma et al. 2020). In the face of dwindling freshwater supplies, and an increasing require-

“…Salinity stress causes an imbalance in the uptake of mineral nutrients and their distribution within the plants [8]. Salinity prompts heavy metals' accumulation and adversely affects nutrient contents in soil and plants, thereby reducing crop yields [9]. The study was undertaken by Alam [10] to determine the effects of varied salinity regimes on the morphological traits (plant height, number of leaves, number of flowers, fresh and dry weight) and major mineral composition of 13 selected purslane accessions.…”

The main purpose of the two consecutive experimental studies presented here was to compare the effect of salinity on nutrients in leaves of the halophytic plant species Portulaca oleracea L. and in soil. The first experiment was conducted to study the effect of salinity on plant growth, biomass accumulation, yield, root layer development, salt accumulation, and the dynamics of changes in mineral substances in plants and soil. In the second experiment, P. oleracea seeds were sown directly into salinized soil (treated immediately before plant growth) to determine the nutrient levels in leaves and soil. Three salinity treatments (saline water solution with NaCl: T1, 5 dS m−1; T2, 9.8 dS m−1; and T3, 20 dS m−1) and a control treatment (T0, 1 dS m−1) were used in the first experiment. The soil in the second experiment was used in a previous study (performed immediately before P. oleracea growth) (salinized soil: T1, 7.2 dS m−1; T2, 8.8 dS m−1; T3, 15.6 dS m−1; T0, 1.9 dS m−1). The plants were irrigated with tap water at amounts in the range of 0.25–0.50 L/pot. Analysis of the experimental results showed that P. oleracea is resistant to salinity, is able to remove ions (400–500 kg ha−1 NaCl), and can be grown in saline soil. The results indicated that P. oleracea is able to grow in high-salinity soil. This finding was confirmed by the dry matter obtained under high-salinity conditions. Salinity stress affected nutrient uptake in leaves and soil.

“…Sewage sludge is a likely by-product of the operations of wastewater treatment plants (Ankush et al 2021), and its rapidly increasing production is a key issue in many developing countries. Furthermore, it can be utilized as a source of fertilizer (Roy et al 2019, Sharma andDhaliwal 2019).…”

The present two-year experiment (2017-19) evaluated the impact of domestic sewage sludge (SS) on yield parameters and soil nutrient status under the pearl millet-wheat system using saline irrigation. The field study consisted of three irrigation treatments [canal water (0.35 dS/m); saline water (8 and 10 dS/m)], and five fertilizer treatments [control, SS (5 t/ha), SS (5 t/ha)+50% recommended dose of fertilizers (RDF), SS (5 t/ha)+75% RDF and 100% RDF]. The results revealed a significant reduction in the biological yield and yield attributes, and protein content of both crops with increasing salinity levels of irrigation water during both the years. However, all these parameters recorded significantly highest values under 100% RDF which was statistically at par with SS (5 t/ha) + 75% RDF treatment. The soil available sulphur (S) was significantly increased with 8 and 10 dS/m EC of saline water over canal water (0.35 dS/m) irrigation. But, SS (5 t/ha) + 75% RDF obtained 36.7 and 22.3% higher available S over control and 100% RDF, respectively. No significant effects were made in DTPA-extractable micronutrients (Fe, Mn, and Cu) with saline irrigation except Zn, which was reduced under saline environment. SS added treatments obtained higher micronutrient concentration over control. Hence, SS incorporation has proven useful in sustainable crop production and improved micronutrient availability in the soil.
