Influence of biochar on soil physicochemical traits and Triticum durum L. physiology during abiotic stress

قواسمية لؤي,

Résumé: Improving soil nutrient reserves through effective land management practices and pasture utilization is a continuing focus in agricultural discussions. Among the various methods aimed at boosting crop productivity, the use of mineral or organic fertilizers is prominent. Biochar, a carbon-rich substance derived from the pyrolysis of organic residues, is commonly employed as a soil amendment to enhance fertility and improve soil characteristics. This study aims to evaluate the impact of biochar on soil physicochemical properties and the yield of a vital forage crop: durum wheat. Three different doses of biochar were applied (D0 = 0g of biochar, D1 = +20g/pot, and D2 = +60g/pot), in conjunction with two types of water and salt stress. Water stress levels were categorized into four stages (S1 = 100%, 80%, 40%, and 20% of field capacity), while salt stress was administered at three varying concentrations: S0 = 0g of NaCl/l, 4g of NaCl/ l, and 9g of NaCl/l. The results indicate an increase in pH (7.77) and electrical conductivity (1369.13 µS/cm), accompanied by a noticeable improvement in nitrates (7.36 mg/g of soil). Significant increases were also observed in total carbon (2.83%) and soil moisture (8.81%), along with a substantial accumulation of active limestone (3.60%). The plant's response to biochar was particularly notable, especially in terms of chlorophyll levels (3.88µg/g FW) and leaf water content (45.54%).

Résumé: The objective of this study is to characterize the bacterial strain Bradyrhizobium sp. (Lotus) and to determine its resistance to trace metal elements (TM) such as copper (Cu(II)) and cadmium (Cd(II). Bradyrhizobium sp. (Lotus) was isolated from nodulated plants of Lotus ornithopodioïdes. Different characteristics of the strain were evaluated, such as growth, bacterial mobility, enzyme and polysaccharide production. The minimum inhibitory concentration (MIC) of TM was determined in vitro and in silico by measuring the optical density at a specific wavelength. The isolate is identified as Bradyrhizobium sp. (Lotus ), which is a Plant Growth Stress Regulating Bacteria (PGSRB) Gram-negative and slow growing, producing succinoglycan, mobile, possessing urease activity. The isolate produces Indole Acetic Acid (IAA) at 70.6 µg/ml. Bradyrhizobium sp. (Lotus) showed more pronounced resistance to Cd(II) compared to Cu(II). The MIC of Cd(II) was estimated in silico to be approximately 10 gL -1 , while the MIC of Cu(II) was 2 gL -1 . Statistical analyzes confirmed a significant relationship between the concentration of TM and the number of bacterial cells. This study made it possible to characterize the bacterial strain Bradyrhizobium sp. (Lotus) and determine its resistance to TM. The results suggest that this strain can be used in remediation or bioremediation applications involving environments contaminated with heavy metals such as copper and cadmium
