Figures & Tables (fcr-figures-and-tables)

Exhibits are where an agronomy reviewer checks whether the result is real and general. At FCR every

exhibit must be self-contained and quantitatively complete: units, sample/replication, and a

measure of error or variability (SE, SED, or LSD) belong on the exhibit itself.

When to trigger

• Designing the main results table/figure or a key descriptive exhibit
• Deciding what belongs in the article vs. supplementary material
• A reviewer found an exhibit unclear, mislabeled, or missing error/units
• Presenting G×E, response curves, or model evaluation

Principles

1. Self-contained. A reader should understand each exhibit from its caption, axis/column labels,

and footnote alone. State the **crop, cultivar(s), environments (sites×seasons), N/replication,

units (SI)**, and what the value is (mean? adjusted mean?).

1. Show the error. Yield and treatment means need SED or LSD (with α and df) or error bars

defined in the caption — never bare means. For curves, show fitted line + CI and the data.

1. Right exhibit for the question. Use a response curve for quantitative factors (N, water,

density); an AMMI/GGE biplot or Finlay–Wilkinson plot for G×E; **observed-vs-simulated with the

1:1 line for model evaluation; time series vs. thermal time/phenology** with weather overlays

for development.

1. Accessible. Colourblind-safe palettes; legible in grayscale; no chartjunk, no 3D, no

needless colour. Vector output (PDF/EPS) for print.

1. Reproducible & consistent. Numbers match the analysis script and the deposited data; table and

figure values are internally consistent and consistent with the text.

Agronomy-specific exhibits

• Yield-gap / boundary-line plots; nitrogen- and water-response curves with fitted models.
• AMMI biplots, GGE biplots, Finlay–Wilkinson stability regressions for multi-environment data.
• Weather (rainfall, temperature, radiation) shown against crop phenology (sowing, anthesis, maturity).
• Maps where spatial/regional variation is the point; observed-vs-simulated panels for modelling.

Exhibit-selection table (question → exhibit → annotation)

The right exhibit follows from the agronomic question. Pair each with the annotation an FCR reviewer

expects.

| Question | Exhibit | Must annotate |

|----------|---------|---------------|

| Yield vs. N/water/density | fitted response curve + points | model, SED or CI, units |

| Genotype ranking | AMMI / GGE / Finlay–Wilkinson | environments labelled, % variance |

| Model performance | observed-vs-simulated, 1:1 line | RMSE, nRMSE, EF, n; validation only |

| Treatment means by environment | adjusted-means table | SED/LSD, α, df, replication |

Worked exhibit vignette (illustrative)

Illustrative. A first-draft Table 2 for the maize MET lists raw plot means with **a/b/c letters

across all 5 N rates** and no error term — two flags at once: letters on a quantitative dose hide the

response shape, and raw means do not match the mixed-model output. The fix is two exhibits: an N

response curve per environment with fitted line and SED bar (α = 0.05), plus an

adjusted-means table with one SED column — both self-contained and reproducible from the script.

Anti-patterns

• Means with no SED/LSD, error bars, or units
• Mean-separation letters on a quantitative dose where a response curve is appropriate
• Tables that need the prose to be intelligible (not self-contained)
• Colour-only encoding that fails in grayscale or for colourblind readers
• Exhibit values that don't match the analysis output or the data deposit

Operating pass for Field Crops Research

Treat this skill as an executable review pass, not a prose hint. First lock the crop system, environment structure, GxE logic, and yield or physiology endpoint; then judge whether the current manuscript answers the venue's real reader: agronomy reviewers who expect field-based, multi-environment evidence and crop-level general significance.

• Do the pass: Return a claim-evidence-risk ledger rather than a prose-only diagnosis; every recommendation must point to a manuscript location or missing artifact.
• Return a ledger: give claim / evidence / risk / manuscript location rows, so the next agent can edit rather than rediscover the issue.
• Sibling guard: compare against Agricultural Systems for whole-system modeling, European Journal of Agronomy for agronomic breadth, Crop Science for cultivar or breeding emphasis; if a sibling owns the contribution, recommend re-routing before polishing format.
• Submission-ready gate: do not give final advice until the pack's resources/official-source-map.md has been checked for upload-week rules and the manuscript has one concrete fix for the largest venue-specific risk.
