“…The fresh weight was measured immediately after harvesting, while the dry weight was recorded once the constant weight was obtained by placing it in an oven at 75°C for 48 h [ 37 ]. The leaf area of fully expanded leaves was measured using a leaf area meter [ 38 ].…”

This research was carried out to evaluate the effect of biochar and compost application on Spinacia oleracea growth in cadmium contaminated soil. Cd toxicity decreased plant growth and biomass significantly and also negatively affected the physiological and biochemical attributes of plants. However, the application of biochar and compost improved the contaminated soil by reducing Cd toxicity and causing its immobilization, which in turn improved plant growth. The combined application of biochar and compost significantly (p < 0.05) enhanced biomass and photosynthetic pigments development in plants. The treatments also increased membrane stability index by 45.12% and enhanced water using efficiency by 218.22%, respectively. The increase in antioxidant activities was 76.03%, 29.02%, and 123.27% in superoxide dismutase, peroxidase, and catalase, respectively. The combined application also reduced the cadmium content (reduced 40.14% in root and 51.16% shoot), its translocation (19.67% decrease), and bioaccumulation (52.63% and 40.32% decrease in Cd content in shoot and root, respectively) in spinach plant. Among the two selected varieties of S. oleracea, Desi palak (V1) performed better as compared to Kanta palak (V2). It can be concluded that the combined application of biochar and compost is one of the best strategies to reduce the toxicity level of Cd in plants and to improve their growth.

“…Wagner and Kaupenjohann (2013) found that biochar produced from maize straw applied at 0, 1, 2.5 and 5% in pots reduced the concentration of Zn and Cd but did not reduced the concentration of Cu and Pb in oat grains irrigated with wastewater. More recent finding of Tahir et al (2018) demonstrate that application of cow-manure-derived biochar applied as 3%, 5% and 10% amendment in soil (soil was also applied with 2% cow manure as fertilizer), did not reduce the accumulation of Zn, Cu, Ni and Fe in spinach irrigated with municipal sewage sludge effluent. However, the NUE (nutrient use efficiency) for Zn and Cu was significantly higher in the plants grown in biochar amended soils and irrigated with wastewater, which indicates that these plants accumulated less Zn and Cu per weight biomass production.…”

Present study analysed the influence of slow-pyrolyzed wood-derived biochar on growth performance and heavy metal accumulation in the leaves of spinach grown under groundwater and wastewater irrigation. Biochar was applied in soil as 5% (~30 t·ha−1) and 10% (~60 t·ha−1) amendment. According to results, plant biomass was significantly higher under wastewater than groundwater irrigation. Biochar amendment increased significantly the aboveground plant biomass and root biomass and promoted water use efficiency (WUE). Under groundwater irrigation, biochar amendment at 10% application rate, increased the leaf area index (P < 0.05), while amendment of biochar at all application rates significantly reduced leaf area index under wastewater irrigation (P < 0.05). Application of biochar also reduced accumulation of rhizosphere soil around roots under wastewater irrigation, indicating less exudate production in the rhizosphere of plants. Biochar significantly reduced the concentration of copper (Cu) in under wastewater irrigation. Biochar increased the nutrient use efficiency (NUE) of plants for zinc (Zn) and Cu under wastewater irrigation.

“…Wastewater also contained heavy metals, particularly As, Ni and Cd above the permissible limit which could disturb the various physiological processes and reducing radish growth and yield. Tahir et al reported that wastewater contained significant amount of salt ions and different heavy metals such as Cu, Fe, Pb, Cd, As, Ni and Cr which adversely affected the plant growth and physiological processes, reducing plant growth and yield [35]. Najam-us-Sahar et al, also reported a decline in plant growth and yield with untreated wastewater due to the toxic effect's wastewater on plant physiology [10].…”

Recent climate changes make the use of wastewater an emerging priority in many parts of the world to meet food security. However, wastewater use without adequate precautionary measures may deteriorate soil health as well as crop yield and quality due to the presence of heavy metals. The present study aimed to investigate the protective role of silicon (Si) against the harmful effects of wastewater on growth, yield, and metal accumulation in radish (Raphanus sativus L.). Experimental plan comprised of wastewater and six Si levels (0, 40, 80, 120, 160 and 200 mg Si kg soil -1 as potassium silicate), with five replications. Silicon as potassium silicate (K 2 SiO 3 ) was thoroughly mixed into soil before filling the pots. Recommended dose of Nitrogen (N), Phosphorus (P) and Potassium (K) fertilizers, 960 mg N pot -1 as urea, 960 mg P 2 O 5 pot -1 as triple superphosphate and 1200 mg K 2 O as potassium sulfate, were applied. Results revealed that all levels of added Si could alleviate the deleterious effects of wastewater on plant growth and yield characteristics, more pronounced protective effects at 120 mg Si kg -1 . There was an increase of 53.10% in shoot length, 113.74% tuber length, 50.0% tuber diameter and 68.63% tuber yield plant -1 with 120 mg Si kg -1 compared to wastewater irrigation without Si. It was found that N concentration improved by 37.60% in leaf and 37.58% in tuber, P 48.47% in leaf and 41.37% in tuber while K 39.11% in leaf and 36.38% in tuber with 120 mg Si kg -1 compared to wastewater irrigation without Si. Lead (Pb) concentration reduced by 27.24%, Arsenic (As) 33.89%, Nickel (Ni) 35.13%, Cadmium (Cd) 32.87%, and Chromium (Cr) 57.14% in radish leaves with 120 mg Si kg -1 compared to wastewater irrigation without Si. Moreover, plant available fraction of heavy metals in soil also markedly reduced with Si under wastewater irrigation. In conclusion, Si could protect radish plants against wastewater-induced metal toxicity by improving the concentration of N, P and K while decreasing Pb, As, Ni, Cd and Cr in plants. Wastewater could efficiently be used for growing radish by amending with Si, particularly at 120 mg Si kg -1 . However, future studies on wastewater utilization with Si can be extended to other vegetables.
