The Changes in Various Physio-Biochemical Parameters and Yield Traits of Faba Bean Due to Humic Acid Plus 6-Benzylaminopurine Application under Deficit Irrigation

Implementing the deficit irrigation pattern has become a major strategy in crop production systems. However, using less water than is required to irrigate crops associated with changes plant physiology and lower productivity. Therefore, current research aimed assess integrated effect of humic acid cytokinin on faba bean under deficit. Under two levels (full irrigation, FI DI), treatments (without addition, H0 addition 10 kg ha?1, H10) concentrations spray, C0 spraying 25 mg L?1, C25), growth, physiology, productivity were evaluated. The experiment was implemented for winter seasons 2019/20 2020/21 performed split–split plots design three replicates. findings revealed that low supply (DI), H10 plus C25 most efficient treatment enhancing growth. All physiological traits estimated DI showed remarkable increases application both seasons. proline, catalase, total soluble sugars due 31.4 31.8%, 51.9 55.1% as well 43.8 46.6%, first second seasons, respectively. There no significant difference between × phosphorus content season produced similar number pods plant?1 seed yield bean. Conclusively, combined achieved nutrient homeostasis, adjusting biochemical compounds
