Abstract: (6 Views)
This study was conducted to evaluate the effects of biochar and phosphorus application on the biochemical characteristics of barley (Hordeum vulgare L.) grown in salt-affected soil. The experiment was arranged as a factorial based on a completely randomized design (CRD) with three replications in the research greenhouse of Mohaghegh Ardabili University during 2022. The experimental treatments included four types of biochar (no biochar as control, raw biochar, phosphoric acid-modified biochar, and nitric acid-modified biochar) and three levels of phosphorus (no phosphorus, 50 mg/L, and 100 mg/L). Measured parameters included hydrogen peroxide content, malondialdehyde (MDA), proline, soluble sugars in roots and leaves, and root fresh weight. The results showed that the highest leaf hydrogen peroxide content and chlorophyll b were observed in the treatment with nitric acid-modified biochar without additional phosphorus. The lowest chlorophyll b content was recorded in the same biochar treatment under no phosphorus application, which was approximately 20.64% lower than the nitric acid-modified biochar treatment with no extra phosphorus. The highest root hydrogen peroxide content was observed in the 100 mg/L phosphorus treatment, showing a significant increase of about 91% compared to the control. The maximum total chlorophyll and leaf proline contents were recorded under the control treatment with no phosphorus application. The lowest leaf hydrogen peroxide content (20.64% less than the highest) was observed in the control biochar treatment with high phosphorus. The highest leaf soluble sugar content was obtained in the control biochar with high phosphorus, while the maximum root soluble sugar was found in the control treatment. The highest leaf MDA content was recorded in the treatment without additional phosphorus, while the highest average root MDA content occurred in the high phosphorus treatment. Overall, the application of nitric acid-modified biochar in combination with high phosphorus levels was identified as the most effective treatment in mitigating the adverse effects of salinity stress on barley plants.
