Introduction situates the research question in a clear agricultural and physiological context
Well‐justified independent variable selection linked to real‐world fertilizer ranges
Comprehensive table of controlled variables (seed mass control) enhances reproducibility
No procedure to ensure uniform cavity volume in the egg tray, risking pot‐to‐pot variability
Minor ambiguities in methodology description (raw‐data table format confusion, ANOVA setup unclear)
Preliminary trials lack specified replicate number, reducing transparency
Correct calculation of means, standard deviations and execution of one‐way ANOVA
Presentation of both raw and processed data with units and a summary table
Clear communication of data processing steps despite minor formatting issues
Inconsistent significant figures and cluttered raw data table layout
Uncertainty consideration is present but missing propagation and percentage errors
Minor calculation inaccuracies (growth rate over 12 vs. 13 days, R² from linear trend)
Conclusion is directly tied to the processed data, quantitatively identifying the 0.6 M optimum
Mechanistic explanation linking zinc inhibition and oxidative stress is clear and scientifically appropriate
Terminology inconsistencies (fluctuation vs. increase) create slight ambiguity
Comparison to external studies remains superficial, lacking deeper quantitative or mechanistic contrast
Four specific methodological weaknesses are identified with discussion of their likely impacts
Realistic, relevant improvements are proposed for each limitation
Depth of explanation for the relative impact of limitations is uneven
Effect sizes or expected magnitude of improvement are not elaborated
