| Abstract | ||
| Managing rice cultivation under salt stress in arid and semi-arid regions is a considerable challenge for ensuring food security and sustainability while enhancing rice production. This research was conducted during the 2022 and 2023 seasons at the Experimental Farm of El-Sirw Agriculture Research Station, located in Damietta Governorate, Egypt, aiming to identify an anti-salinity substance that could effectively assist rice plants in coping with salinity stress. The experiment a employed a split-plot design arrangement in randomized complete block design (RCBD) with four replications. The main plots featured rice varieties; Giza179 and Sakha108, while the subplots included treatments such as control, Salicylic acid (SA), Gibberellic acid (GA3), folic acid vitamin (B9), elements as NPK and micronutrients(E), Glycine betaine (GB) and their combination which were applied at three growth stages. The outcome demonstrated that all treatments improved the examined characteristics compared to the control treatment. The optimal treatment involved spraying a gibberellic acid on the foliage during mid tillering, applying elements at panicle initiation, and administering salicylic acid at the booting stage, which improved biochemical traits, the effectiveness of the antioxidant defense system, agronomic characteristics, yield attributes, rice yield and cost-effective compared to other treatments, followed by the mixture of the materials utilized in the study. In conclusion, the external application of gibberellic acid, nutrient elements, and salicylic acid at specific growth stages provides an efficient strategy to alleviate oxidative stress in salt-affected soils, thereby improving rice growth, productivity, and economic return. | ||
