name: fcr-topic-selection description: Use when deciding whether an agronomy or crop-science project fits Field Crops Research (FCR) and which article type to target. FCR's defining test is field-based agronomic significance with multi-season/-environment relevance — it rejects controlled-environment-only, single-site single-season, horticultural/woody-perennial, and corroborative/descriptive/local-only work. Helps frame the question; it does not collect data.

Topic Selection & Scope Fit (fcr-topic-selection)

FCR is a field-agronomy journal. The bar is not "a new result in my plot" — it is "a field-based insight of general relevance to field crops." Use this skill to pressure-test fit before you invest, because FCR's scope boundary is strict and a mismatch is a fast desk rejection.

When to trigger

• Choosing among possible projects or framings for an FCR submission
• A reviewer/colleague said the work feels "controlled-environment," "too local," or "descriptive"
• Deciding between an Original Research Paper and a Short Communication
• Considering a Review or Opinion piece (propose to the Editors-in-Chief first)

The FCR scope gate (must clear all four)

1. Field-based. Conducted in the field, not exclusively under controlled conditions (greenhouse, pots, or any system that constricts root growth). A controlled-environment component is fine only when integrated with, and subordinate to, field results.
2. Multi-season / multi-environment relevance. Field experiments should, unless exceptional circumstances apply, span at least two seasons and/or multiple locations/environments. A single-site, single-season trial usually fails the gate.
3. A field crop. Crops grown for food, fibre, feed, or biofuel. Out of scope: horticultural (vegetable/fruit) species, woody perennials, medicinal and non-cultivated species, and natural grasslands.
4. General significance, not local/descriptive. Must show new scientific insight, original technology, or a novel method of general application — not corroborative, purely descriptive, or of only local interest.

Frame the agronomic contribution

Angle	Make it FCR-worthy by…
Yield / yield gap	quantify the gap vs. potential/water-limited yield and what closes it
Crop physiology	connect a process (RUE, WUE, partitioning, phenology) to yield formation
Agronomy / management	show a management response that travels across environments, with G×E×M
Cropping systems	demonstrate system-level effects (rotation, intercrop, residue) over seasons
Crop modelling	calibrate/validate against field data and use the model to generalise beyond the sites

Including yield data is encouraged — it ties the work to the biophysical processes FCR cares about.

Article-type choice

• Original Research Paper — full field/modelling study, multi-environment, general relevance.
• Short Communication — one complete, focused finding that will not be part of a later paper.
• Review — critical synthesis; normally invited, but send a brief proposal/outline to the Editors-in-Chief first.
• Opinion Paper — a reasoned perspective on an issue in field-crop science.
• Loomis Review — major review by invitation only.

Scope-boundary calls (borderline cases ruled)

The gate is strict, so the hard calls are the borderline ones. These rulings reflect FCR's stated exclusions; confirm the current scope wording against the journal's aims & scope, which can change.

Borderline case	Likely call	Reason
Greenhouse mechanism + one supporting field season	In scope only if field results are the spine	controlled-environment cannot be main evidence
Maize agronomy, 2 seasons, 1 site	Borderline — add sites or a modelling generalisation	one location weakens multi-environment relevance
Potato tuber-quality trial	Likely out — horticultural framing	vegetable/horticultural species risk
Forage grass in a cropping rotation	In scope as a feed crop; natural grassland is out	cultivated vs. non-cultivated grassland
Crop model validated on others' field data	In scope if it generalises field results	modelling that extends field evidence is welcome

Worked scope vignette (illustrative)

Illustrative. A student has greenhouse data showing a root-architecture trait improves P uptake, plus 1 field season at 1 site (3.9 vs. 3.5 t ha⁻¹). As framed — "trait improves P uptake and yield" — it fails twice: the mechanism rests on controlled-environment pots, and the field evidence is a single site-year. The FCR-worthy reframe keeps the physiology as context and rebuilds the spine around the field: test the trait's yield and P-uptake response across 2 seasons × 4 environments on a soil-P gradient, so the claim becomes "the trait closes a P-limited yield gap across low-P environments."

Anti-patterns

• A pot/greenhouse-only study dressed up as agronomy (out of scope)
• "First time measured in my region" as the whole contribution (local/descriptive)
• One season at one site with no path to multi-environment relevance
• A horticultural, woody-perennial, or non-cultivated species (wrong journal)
• A result with no yield or biophysical-process link
