Drought stress severely impacts plant growth and agricultural productivity, necessitating strategies to enhance drought tolerance. This meta-analysis synthesizes data from 48 peer-reviewed studies evaluate the effects of exogenous nitric oxide (NO) on growth, photosynthesis, antioxidant defense, osmoregulation under conditions. Results show that NO significantly improves shoot length, root dry weight, weight by 66.60%, 29.38%, 26.71%, 16.17%. Photosynthetic rate, stomatal conductance, intercellular CO₂, Leaf relative water content, total chlorophyll, chlorophyll a b was also improved 17.98%, 67.95%, 12.12%, 10.20%, 19.68%, 52.26%, 39.91%, respectively. Antioxidant enzyme activities, including superoxide dismutase, catalase, peroxidase, ascorbate were elevated 13.69%, 22.60%, 16.98%, 19.33%, Oxidative markers, hydrogen peroxide, superoxide, malondialdehyde, reduced 18.63%, 22.01%, 18.22%, Osmotic regulators, proline, soluble sugars, proteins, increased 17.01%, 18.34%, 30.40%. Subgroup analyses reveal NO's effectiveness is influenced environmental factors, species, application methods. confirms photosynthetic efficiency, osmotic regulation stress. The heterogeneity different conditions highlights importance improving methods, concentrations, These findings encourage focused research maximize benefits in enhancing crop resilience, promoting sustainable practices.
