“…Conversely, the sole application of compost caused a noticeable augment in SOD, CAT, and POX activities [ 64 ]. However, it was noted that SOD, CAT, and POX activities are further increased under the coupled application of compost and PGPR perhaps owing to reduced Na uptake [ 65 ]. In harmony with our findings, prior investigations presented augmented SOD, CAT, and POX under abiotic stress [ 66 ].…”

Plant growth and crop productivity under unfavorable environmental challenges require a unique strategy to scavenge the severely negative impacts of these challenges such as soil salinity and water stress. Compost and plant growth-promoting rhizobacteria (PGPR) have many beneficial impacts, particularly in plants exposed to different types of stress. Therefore, a field experiment during two successive seasons was conducted to investigate the impact of compost and PGPR either separately or in a combination on exchangeable sodium percentage (ESP), soil enzymes (urease and dehydrogenase), wheat physiology, antioxidant defense system, growth, and productivity under deficient irrigation and soil salinity conditions. Our findings showed that exposure of wheat plants to deficit irrigation in salt-affected soil inhibited wheat growth and development, and eventually reduced crop productivity. However, these injurious impacts were diminished after soil amendment using the combined application of compost and PGPR. This combined application enhanced soil urease and dehydrogenase, ion selectivity, chlorophylls, carotenoids, stomatal conductance, and the relative water content (RWC) whilst reducing ESP, proline content, which eventually increased the yield-related traits of wheat plants under deficient irrigation conditions. Moreover, the coupled application of compost and PGPR reduced the uptake of Na and resulted in an increment in superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX) activities that lessened oxidative damage and improved the nutrient uptake (N, P, and K) of deficiently irrigated wheat plants under soil salinity. It was concluded that to protect wheat plants from environmental stressors, such as water stress and soil salinity, co-application of compost with PGPR was found to be effective.

Shrimp waste is rich in organic compounds and essential plant nutrients, e.g., calcium (Ca), and converting these wastes to organic fertilizer is important for environmental preservation and to achieve sustainable agricultural management. In the current study, Ca-rich biochar was prepared from shrimp wastes (SWB) by pyrolysis at 300 °C. We hypothesized that the Ca-rich biochar will help in solving the problem of plant growth in saline soil by reducing sodium (Na) uptake and mitigating oxidative stress. The current study aimed to investigate the effect of SWB on the quality of saline sandy soil and the mechanism of salt resistance in pearl millet (Pennisetum glaucum L.). Pearl millet plants were planted in saline sandy soil (10 dS m−1) in wooden boxes (1.3 × 0.8 m size and 0.4 m height), and 5 doses (0, 1.0, 1.5, 2.0, and 2.5% (w/w)) of SWB were added. SWB application increased the soil quality and nutrient uptake by pearl millet plants. The highest rate of SWB increased the soil microbial biomass carbon and the activity of dehydrogenase enzyme by 43 and 47% compared to the control soil. SWB application reduced the uptake of sodium (Na+) and chloride (Cl−) and increased the K/Na ratio in the leaf tissues. SWB addition significantly increased the activity of antioxidant enzymes, e.g., ascorbate peroxidase (APX), polyphenol oxidase (PPO), and pyrogallol peroxidases (PPX). The application of 2.5% SWB to the saline soil increased the soluble carbohydrates and proline in plant leaves by 75 and 60%, respectively, and reduced the malondialdehyde (MDA) by 32% compared to the control. SWB enhanced the antioxidant defense and mitigated oxidative stress by improving the synthesis of osmoprotectants, e.g., soluble carbohydrates and proline. Sandy saline soils in arid and semiarid areas suffer greatly from low organic matter contents, which reduces the soil quality and increases the risk of salt during plant growth. The high organic matter and calcium content (30%) in the shrimp waste-derived biochar improved the quality of the saline sandy soil, reduced the uptake of toxic salts, and increased the quality of the forage material. The addition of recycled shrimp waste to saline low-fertility soils improves soil productivity and is safe for soil health.

“…Cadmium stress significantly reduced the root and shoot growth and biomass production of mash beans plants (Figures 1 and 2). Cadmium stress disturbs plant metabolic processes, nutrient uptake, photosynthetic pigments, biological structures, and anti-oxidant activities which, therefore, reduces the root and shoot growth and subsequent biomass production [64,65]. Additionally, Cd stress also inhibits cell expansion and elongation, which is also a major reason for Cd-induced reduction in root and shoot growth and biomass production (Figures 1 and 2) [66].…”

Cadmium (Cd) stress is a serious environmental hazard that has devastating impacts on plant growth and productivity. Moreover, the entrance of Cd into the human food chain by eating Cd-contaminated food also poses serious health issues. Organic amendments (OA) possess an excellent potential to reduce the adverse impacts of Cd stress. Therefore, the aim of this study was to determine the potential of different OA in improving the mash beans growth and yield grown under Cd-contaminated soil. The soil was spiked with different concentrations of Cd (0, 10 and 20 mg/kg) and subjected to different OA, i.e., control, cow manure (5%), sugarcane press mud (5%) and a combination of cow manure (2.5%) and sugarcane press mud (2.5%). Results indicated that Cd stress induced a significant reduction in growth and yield traits, leaf water status, photosynthetic pigments, protein accumulation and anti-oxidant activities. However, the application of OA appreciably reduced the Cd-induced toxic effects and caused a significant increase in growth and yield. The application of 5% sugarcane press mud remained the top performer and it increased the mash bean growth and yield through improved photosynthetic pigments, leaf water status (56%) and reduced Cd uptake (18%), hydrogen peroxide (H2O2) production (38.52%), electrolyte leakage (EL) (42.13%) malondialdehyde (MDA) accumulation (55.88%) and increased accumulation of soluble protein (60.15%) and free amino acids (54%) through improved activities of anti-oxidant enzymes. Therefore, these findings suggested that the application of sugarcane press mud enhanced the growth and yield through reduced Cd accumulation, enhanced photosynthetic pigments, leaf water status, protein and amino accumulation and reduced H2O2, EL and MDA accumulation through a stronger anti-oxidant defense system.
