| Abstract: |
Egypt suffers from the dilemma of “absolute scarcity” of fresh water and the poor quality of available non-conventional water resources. The problem is further complicated by rapid population growth and climate changes. Available information indicates that individually and/or dual addition of soil amendments such as biochar (B), compost (C), rock phosphate (RP) and phosphorene (P)(trade name of phosphate-solubilizing bacteria) help crop plants to tolerate salinity and sodicity of soil and irrigation water. However, no data is currently available on the potential of BCRPP mixture to utilize poor quality waters for irrigation. Therefore, the aim of this study was to evaluate the potential of BCRPP mixture in mitigating salinity and sodicity stresses of irrigation water on wheat. In a pot trial, soil was amended with BCRPP mixture at four different rates (0, 2.5, 5, and 10%, w/w) while wheat (Triticum aestivum L.) was grown under two type of irrigation water; fresh water (EC= 0.41 dS m-1; SAR= 2.03 and Adj. SAR 2.44) or highly saline-sodic water (EC= 6.23 dS m-1; SAR= 37.82 and Adj. SAR 52.95). Soil properties, plant performance, and nutrient uptake were determined. Results significantly indicated improvements in most growth and development wheat parameters, ie Photosynthetic pigments concentration (Chlorophyll A, B, and total, and carotenoids), non-enzymatic antioxidants (Ascorbic Acid, ASA), and organic osmolytes (proline and total soluble sugars, TSS) in addition to biomass and grain yields. Contents of essential nutrients in wheat parts also increased due to applying of BCRPP mixture, while the content and proportions of Na+ decreased. There …
