“…The experiment was set up using a standard response surface methodology (RSM), namely central composite design (CCD) for the optimization of the selected independent variables. Seed disinfection and germination were carried out as per Roy et al (2021b). Seedlings were trimmed to 10 plants per pot at the 5 th true leaf stage, and then the 5 different W doses were applied and followed for two months.…”

“…However, in areas with acute water shortages like Northwest China, revegetation depends profoundly on artificial irrigation, since groundwater is usually inaccessible in that region (Gao et al, 2016). In practice, covering soil, and/or inorganic and organic amendments are normally applied to support the revegetation in such degraded land (Roy et al, 2022(Roy et al, , 2021b(Roy et al, , 2021dXie and van Zyl, 2020).…”

“…There is substantial evidence that compost and biochar can increase soil fertility status and a plant's resistance to stress in degraded environments (Antonious, 2018;Pandey et al, 2021;Ren et al, 2021;Roy et al, 2021b). However, less is known about the impact of the coupling effect of water (W), CMC and BC on the morphological, physiological and biochemical growth responses of O. viciifolia planted on coal-mined spoil.…”

Surface mining is a critical anthropogenic activity that significantly alters the ecosystem, while the use of appropriate revegetation techniques can be considered an important and feasible strategy in the way to improve the ecosystem services of degraded land. In the present study, we carried out a pot experiment to investigate the effects of three different variables on morpho-physiological and biochemical parameters of Onobrychis viciifolia to assess the capability of this species to be used for restoration purposes. Specifically, the variables studied were: (a) water (W) regime, working at five values as regards field capacity (FC) (i.e., 80% FC = highest, 72% FC = high, 60% FC = moderate, 48% FC = low, and 40% FC = very-low dose); and (b) rates of cattle manure compost (CMC) and wood biochar (BC) (weight/weight ratio), working at five rates (i.e., 4.0% = highest, 3.2% = high, 2.0% = moderate, 0.8% = low, and 0% = either no-CMC or no-BC dose). In addition, soil physical-chemical properties and enzyme activities were also investigated at the end of the experimental period. It was found that morphological growth attributes such as plant height, maximum root length, and dry biomass significantly increased with W, CMC and BC applications. Compared to control, moderate-to-high W, CMC and BC doses (W 80 CMC 2 BC 2 ) increased net photosynthesis rate (by 42%), stomatal conductance (by 50%), transpiration rate (by 29%), water use efficiency (by 10%), chlorophyll contents (by 73%), carotenoid content (by 81%), leaf relative water content (by 33%) and leaf membrane stability index (by 30%). Under low-W content, the application of CMC and BC enhanced osmotic adjustments by increasing the content of soluble sugar and the activities of superoxide dismutase, catalase, peroxidase and ascorbate peroxidase, decreasing the oxidative stress, as verified by low levels of hydrogen peroxide, superoxide anion, malondialdehyde and proline contents in leaf tissues. Moreover, application of W, CMC and BC significantly improved soil water holding capacity, available nitrogen, phosphorus and potassium, urease and catalase activities, which facilitate plant growth. These results would aid in designing an appropriate strategy for achieving a successful revegetation of O. viciifolia, providing optimum doses of W (64% field capacity), CMC (2.4%) and BC (1.7%), with the final aim of reaching ecological restoration in arid degraded lands.

“…In sustainable agriculture, biochar addition should be planned according to a specific fertilization scheme taking into account environmental conditions, and chemical fertilization should be at least partially replaced by organic fertilization ( Ayaz et al, 2021 ; Latini et al, 2021 ; Roy et al, 2021 ). In this regard, anaerobic digestate (AD) obtained after biogas production using plant biomass (e.g., maize) and/or manure as a feedstock has been proposed to replace inorganic fertilizer to maintain grassland productivity at less environmental cost ( Walsh et al, 2012 ; Nkoa, 2014 ).…”

This study aims to highlight the major effects of biochar incorporation into potting soil substrate on plant growth and performance in early growth stages of five elite Italian varieties of durum wheat (Triticum durum). The biochars used were obtained from two contrasting feedstocks, namely wood chips and wheat straw, by gasification under high temperature conditions, and were applied in a greenhouse experiment either as pure or as nutrient-activated biochar obtained by incubation with digestate. The results of the experiment showed that specific genotypes as well as different treatments with biochar have significant effects on plant response when looking at shoot traits related to growth. The evaluated genotypes could be clustered in two main distinct groups presenting, respectively, significantly increasing (Duilio, Iride, and Saragolla varieties) and decreasing (Marco Aurelio and Grecale varieties) values of projected shoot system area (PSSA), fresh weight (FW), dry weight (DW), and plant water loss by evapotranspiration (ET). All these traits were correlated with Pearson correlation coefficients ranging from 0.74 to 0.98. Concerning the treatment effect, a significant alteration of the mentioned plant traits was observed when applying biochar from wheat straw, characterized by very high electrical conductivity (EC), resulting in a reduction of 34.6% PSSA, 43.2% FW, 66.9% DW, and 36.0% ET, when compared to the control. Interestingly, the application of the same biochar after nutrient spiking with digestate determined about a 15–30% relief from the abovementioned reduction induced by the application of the sole pure wheat straw biochar. Our results reinforce the current basic knowledge available on biological soil amendments as biochar and digestate.

“…Under stress conditions, the balance of the enzymatic system in the plant is affected, and excess reactive oxygen species produced in the cells aggravate the peroxidation of the cell membrane. In response to this, plants use their enzymatic and non-enzymatic antioxidant defense systems to remove excess reactive oxygen species (ROS) and protect their photosynthetic organs and cell membranes from injury [29]. Non-enzymatic antioxidants such as reduced ascorbic acid (AsA) and reduced glutathione (Glutathione, GSH) are utilized to scavenge harmful substances such as free radicals, peroxides, and reactive oxygen species.…”

Background: Obtaining superior performance of SupraNova and Lark C3 turfgrasses under shade conditions is a challenging task. Both durability and performance of turfgrass are significantly affected by shade. In particular, morphological and physiological adaptation to low light is critical for maintaining quality and overall performance in turfgrass plants. Results: The purpose of this study was to study the response of SupraNova and Lark turfgrass morphology and photo-physiological potential to shading. The plants of 'SupraNova' and 'Lark' were collected from the lawn plots of the Horticulture Research Center of Northeast Agricultural University of China for 2 years and treated with gradient shading 35.62% after 2 months of culture, normal light intensity 70.79 % and 93.45% with full sun as the contrast represented by CK for comparison. Lark showed TQ and TCI in shady stage compared with SupraNova. Lark showed strong resistance to MDA, H2O2, O2-, SOD, POD, CAT and AsA, indicating that the antioxidant system of C3 turfgrass at 35.6% shade level. Under 70.79% shade treatment, MDA, H2O2, O2-, SOD, POD, CAT and AsA of the two cultivars decreased the most, and the longer the shading time, the average daily growth of the two turfgrasses increased first and then decreased. Lark outperformed SupraNova throughout the shading treatment, with 70.79% and 93.45%, respectively. Lark showed increased Chl A and Chl (A/B) in response to different shading levels, while SupraNova had the highest concentrations of Chl B and total Chl. Chlorophyll fluorescence qP, ETR, and Fv/Fm decreased significantly when shaded at 93.45%;Conclusion: The results of this study proved that decrease was more significant in SupraNova than Lark, and shading caused more severe changes in leaf morphology and anatomical structure than Lark turfgrass has the highest negative tolerance than SupraNova turfgrass, which is due to the better photosynthetic product transport capacity of Lark plants. In its anatomical structure, and" vascular bundle sheath structure, which enables it to have higher photosynthetic efficiency to adapt to negative stress. SupraNova and Lark first increased and then decreased with the increase of shade degree
