name: fcr-cover-letter description: Use when writing the cover letter for a Field Crops Research (FCR) submission to the Editors-in-Chief. The letter must establish scope fit (field-based, multi-season/-environment, a field crop, generally significant), state the novel contribution and article type, and confirm originality and data availability. Drafts the letter; it does not contact editors or invent claims.

Cover Letter (fcr-cover-letter)

The cover letter is the editor's first scope check. Because FCR has a strict scope boundary, the letter's job is to show — in a few sentences — that the paper is field-based, multi-environment, on a field crop, and generally significant, and to name the novel contribution clearly. A vague letter invites a fast desk rejection.

When to trigger

• Preparing the submission package and need the cover letter
• Pitching a Review or Opinion proposal to the Editors-in-Chief first
• Explaining why a borderline design (e.g., exceptional single-season circumstances) still fits scope

What an FCR cover letter must do

1. Address the Editors-in-Chief and name the journal and the article type (Original Research Paper / Short Communication / Review / Opinion).
2. Establish scope fit in one short paragraph. State that the work is field-based, spans ≥ 2 seasons and/or multiple environments, concerns a field crop, and offers general relevance (not local/descriptive). If a single-season design is unavoidable, justify the "exceptional circumstances" explicitly.
3. State the novel contribution. One or two sentences: what new scientific insight, technology, or method of general application the paper provides, and the headline quantitative result.
4. Confirm the essentials. Original work, not under consideration elsewhere; all authors approve; a data-availability position; any generative-AI use disclosed; suggested/excluded reviewers if the journal invites them.
5. Be brief and specific. Roughly one page; no hype; let the agronomic significance speak.

Skeleton

Dear Editors-in-Chief,

We submit "[Title]" for consideration as an [article type] in Field Crops Research.

[Scope + contribution: field-based study across N seasons and M environments on
<field crop>; the novel finding is ___, quantified as ___; it matters generally
because ___.]

The work is original and not under consideration elsewhere; all authors approve
submission. Data availability: [shared in <repository> / restricted because ___].
[We did/did not use generative-AI tools, disclosed in the manuscript.]

[Optional: suggested reviewers / conflicts.]

Sincerely, [Corresponding author, affiliation, contact]

Scope-fit sentence bank (illustrative)

The editor's eye lands on one paragraph: does it clear the gate? Each row pairs a vague opener with one that pre-clears the scope screen.

Weak	Scope-clearing rewrite (illustrative)
"We studied nitrogen on wheat."	"Across 2 seasons and 5 environments, we quantify how N-use efficiency of wheat cultivars varies with N supply."
"This is the first such study in our area."	"We resolve a contested mechanism — whether deficit irrigation raises WUE — across a vapour-pressure-deficit gradient."

Worked cover-letter vignette (illustrative)

Illustrative. Draft 1 of a maize-MET letter paraphrases the abstract and never names the article type or environment spread — a letter the editor cannot scope-check. The repaired opening names it an Original Research Paper, states the work is field-based across 2 seasons × 4 environments on maize, gives the headline result (a 0.9 t ha⁻¹ environment-conditional advantage), and confirms originality, data availability, and AI disclosure — letting the editor tick every scope box at once.

Anti-patterns

• A letter that summarises the abstract but never states scope fit
• Claiming novelty without the quantitative finding or its general relevance
• Hiding a single-site/single-season limitation instead of justifying it
• Overstating impact; emotional or boilerplate appeals
• Forgetting originality, data-availability, or AI-disclosure statements

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.
