| Abstract | ||
| Currently in Egypt, using the agricultural drainage water (ADW) for irrigation purposes as a partial or complete alternative to fresh water (FW) is unavoidable. Therefore, it must find approach that will reduce this harm and maintain productivity without a significant decline in productivity. For this purpose, a field experiment was implemented during two successive seasons (2023/24 and 2024/25) to evaluate applying enhanced biochar (EB) combined with natural extracts on the faba bean irrigated with ADW. Three factors were studied under split-split plot design, as the main factor was the irrigation water type (FW and ADW), while the sub main factor was applying EB [applied at 2.4 ton/hectare]. Also, four foliar treatments [control, green tea, turmeric, and grape seed extracts at a rate of 10.0 cm3 L-1 for each extract] were arranged in the sub-sub plots. The growth criteria (e.g., fresh and dry weights), quantitative and qualitative traits (e.g., seed yield, carbohydrate and protein contents) of faba bean were evaluated. The values of the evaluated parameters under FW treatment were higher than that under AWD treatment. Additionally, the boichar led to improvements in all studied criteria. The superior natural extract was grape seed followed by green tea then turmeric. On the other hand, applying the biochar combined with the grape seed extract under irrigation with ADW had a non-significant effect on the faba bean performance compared to the irrigation with FW without any studied substances. Therefore, it can be recommended to incorporate this approach into the management of low-quality irrigation water. | ||
