Stress modifiers are recognized as biostimulants providing beneficial effects on various plant species. However, the specific potential of modulators such melatonin, chitosan, humic acid, and selenium in enhancing resistance ajwain (Carum copticum L.) plants to water scarcity remains an open question. To address this knowledge gap, we conducted a randomized, field block-designed factorial experiment over two years (2022–2023) compare effectiveness these mitigating impact shortage plants. This study involved three irrigation regimes: 100% capacity (FC100%—unstressed), 75% deficit (FC75%—moderate) 50% (FC50%—severe), four modifier treatments (melatonin, selenium), plus untreated controls. Plant growth, seed yields, essential oil production, well eco-physiological traits were studied assess efficacy compounds stress modulators. Water regimes applications, single factor or synergy, significantly affected physiology yield, highlighting importance sustainability agricultural practices. Compared FC100%, biological chlorophyll, nutrient content decreased under FC75% FC50%, while proline, soluble sugars, flavonoids, phenols antioxidant enzymatic activity increased. Notably, regardless type modulator used, application improved all physiological attributes moderate severe deficits. Among compounds, melatonin induced most pronounced effects, leading higher fixed relative leaf content, chlorophyll concentration, activity. Our results demonstrate that effectively function against by preserving promoting saving. These findings provide valuable insights into their use nature-based solution for addressing sustainable agriculture climate change challenges.
