“…The same pattern of increase in K + concentration was recorded in the current work, which might be related to the controlling mechanism of Na + due to N and Zn fertigation. As a divalent macromolecule, calcium plays an imperative role in membrane integrity, signaling, and sustaining the metabolism of crop plants 76 . The current illustration indicates a higher level of Ca 2+ , which is vital for normal metabolic processes and growth.…”

An ample amount of water and soil nutrients is required for economic wheat production to meet the current food demands. Nitrogen (N) and zinc (Zn) fertigation in soils can produce a substantial wheat yield for a rapidly increasing population and bring a limelight to researchers. The present study was designed to ascertain N and Zn’s synergistic role in wheat growth, yield, and physio-biochemical traits. A pot experiment was laid out under a complete randomized design with four N levels (N1-0, N2-60, N3- 120, and N4-180 kg ha−1), Zn (T1-0, T2-5, T3-10, and T4-15 kg ha−1) with four replications. After the emergence of the plants, N and Zn fertigation was applied in the soil. The growth traits were considerably increased by combined applications as compared to the sole applications of the N and Zn. The photosynthetic pigments were found maximum due to combined applications of N and Zn, which were positively associated with biomass, growth, yield, and wheat grain quality. The combined application also substantially enhances the antioxidant enzyme activities to scavenge the ROS as H2O2 and reduce lipid peroxidation to protect the permeability of the biologic membranes. The combined higher applications of N and Zn were more responsive to ionic balance in a shoot by maintaining the Na+ for osmotic adjustments, accumulating more Ca2+ for cellular signaling; but, combined applications resulted in K+ reduction. Our present results suggest that appropriate sole or combined applications of N and Zn improve wheat's growth, yield, and antioxidant mechanisms. Previous studies lack sufficient information on N and Zn combined fertigation. We intend to investigate both the sole and combined roles of N and Zn to exploit their potential synergistic effects on wheat.

“…Many studies have proven that Cd pollution has a variety of negative effects on plant growth (Zhao et al, 2021;Kaleem et al, 2022). Cadmium stress significantly (P < 0.05) decreased plant height and leaf area of Soybean by 17.65% and 47.71%, when compared with the control treatment.…”

Cadmium (Cd) is a heavy metal that affects plant growth and yield. Biochar can mitigate the detrimental effect of Cd on plants. To assess effectiveness of wood biochar (WB) in mitigating Cd stress, a pot experiment was conducted with six treatments in Soyabean crop viz., control (0% biochar and no Cd stress), 1.5% WB, 3% WB, 100 mg CdCl2 Kg-1 soil, 100 mg CdCl2 Kg-1 soil +1.5% WB, 100 mg CdCl2 Kg-1 soil +3% WB. The impact of Cd on the growth, physiological status, yield and yield-contributing characters of Soybean were found to be significant (p<0.05). The application of 1.5% and 3% WB significantly (p < 0.05) alleviated Cd toxicity to Soybean under Cd stress conditions. There was no significant difference in the effect of two rates of wood biochar’s (1.5% and 3% WB) on growth, physiological status and yield of Soybean. Therefore, it can be concluded that 1.5% WB is sufficient to reduce toxicity caused by Cd stress in Soybean. SAARC J. Agric., 21(2): 157-168 (2023)

“…Amino acids regulate pH, enzyme synthesis and redox homeostasis [57]. During HM stress, amino acids upregulate osmotic adjustments, maintain integral proteins and ion homeostasis, neutralize redox potential and scavenge ROS by maintaining plant antioxidant levels [58]. However, Cd toxicity induces damage to proteins in the cell cytoplasm [49].…”

Soil contamination with cadmium (Cd) is a severe concern for the developing world due to its non-biodegradability and significant potential to damage the ecosystem and associated services. Industries such as mining, manufacturing, building, etc., rapidly produce a substantial amount of Cd, posing environmental risks. Cd toxicity in crop plants decreases nutrient and water uptake and translocation, increases oxidative damage, interferes with plant metabolism and inhibits plant morphology and physiology. However, various conventional physicochemical approaches are available to remove Cd from the soil, including chemical reduction, immobilization, stabilization and electro-remediation. Nevertheless, these processes are costly and unfriendly to the environment because they require much energy, skilled labor and hazardous chemicals. In contrasting, contaminated soils can be restored by using bioremediation techniques, which use plants alone and in association with different beneficial microbes as cutting-edge approaches. This review covers the bioremediation of soils contaminated with Cd in various new ways. The bioremediation capability of bacteria and fungi alone and in combination with plants are studied and analyzed. Microbes, including bacteria, fungi and algae, are reported to have a high tolerance for metals, having a 98% bioremediation capability. The internal structure of microorganisms, their cell surface characteristics and the surrounding environmental circumstances are all discussed concerning how microbes detoxify metals. Moreover, issues affecting the effectiveness of bioremediation are explored, along with potential difficulties, solutions and prospects.
