Enhancing yield and stress resilience in toria (Brassica rapa L.) through salicylic acid application under moisture stress conditions

Abstract

 Moisture stress is a significant constraint affecting the yield of toria (Brassica rapa var. toria) in rainfed and semi-arid
 regions. Salicylic acid (SA), a plant growth regulator, plays a crucial role in mitigating abiotic stress and enhancing plant
 resilience. This study investigates the impact of foliar application of salicylic acid on the physiological traits, growth
 parameters, and yield of toria under moisture stress conditions. Results indicate that SA application improves
 photosynthetic efficiency, water use efficiency, and antioxidant defense mechanisms, leading to increased seed yield
 and oil content compared to untreated controls. These findings suggest that salicylic acid could be an effective strategy
 for enhancing toria productivity in moisture-deficient environments.
