On-farm variety trial audit
Audit a farm variety comparison from the predeclared question and design through seed-lot identity, randomization, execution, deviations, plot-level measurement, analysis, uncertainty and bounded conclusions.

Orient before entering the field.
Connect the intended outcomes, operating stages, stop conditions, and supporting technology concepts before opening the detailed action sequence.
- 01Separate a designed replicated trial from an observational side-by-side comparison
- 02Verify every treatment back to its variety, seed lot and planter load
- 03Expose field variability, randomization, management differences and operational deviations
- 04Trace reported results to raw plot evidence, exclusions, analysis and exact inference limits
- 01Freeze the question and protocol
Changing outcomes, exclusions or analysis after seeing results makes a comparison easier to sell and harder to trust.
3 field actions ↓ - 02Verify treatment identity and execution
A perfect layout cannot recover from the wrong seed lot, planter carryover, treatment crossover or undocumented substitution.
3 field actions ↓ - 03Audit measurements and exclusions
Yield and quality records can inherit header width, delay, calibration, moisture, sample, edge and missing-data problems that differ by plot.
3 field actions ↓ - 04Reproduce analysis and constrain the conclusion
A numerical difference can be practically unimportant, statistically uncertain or inseparable from field and operational variation.

- G01
This guide provides no experimental design, replication count, statistical model, variety, seed rate, agronomic treatment, yield forecast, purchase or investment recommendation.
- G02
Use qualified agronomists, statisticians, Extension specialists and local protocols before designing or interpreting a trial.
- G03
Never hide failed plots, operational errors, exclusions, missing data, unfavorable results, conflicts of interest or changes made after results were known.
Freeze the question and protocol
Changing outcomes, exclusions or analysis after seeing results makes a comparison easier to sell and harder to trust.
- 01Record the farm decision question, intended population, varieties, comparison or control, primary and secondary response variables, practical relevance and claims excluded
- 02Version field eligibility, blocks, experimental unit, plot or strip geometry, equipment widths, real treatment replication, random allocation, buffers, common management and stop rules
- 03Name protocol, field, execution, measurement, analysis and approval owners; obtain qualified agronomic and statistical review before planting
Verify treatment identity and execution
A perfect layout cannot recover from the wrong seed lot, planter carryover, treatment crossover or undocumented substitution.
- 01Connect randomized treatment code to exact variety, seed lot, container, tender and planter load while protecting blinding where used
- 02Preserve field boundary, plot polygons, as-planted records, equipment state, cleanout and carryover, dates, weather, soil and prior-management context
- 03Log every substitution, missed or doubled area, overlap, drift, crop injury, flooding, wildlife, machinery issue and unequal management with affected plots and status
Audit measurements and exclusions
Yield and quality records can inherit header width, delay, calibration, moisture, sample, edge and missing-data problems that differ by plot.
- 01Trace each response value to plot, harvest or sample event, machine or instrument, calibration and comparison context, units, raw file, operator and time
- 02Check plot and harvest geometry, excluded borders, partial passes, crossover, missing observations, sample custody, laboratory report and corrections
- 03Keep raw, accepted and excluded data together; require reason, author, timing and protocol authority for each status change
Reproduce analysis and constrain the conclusion
A numerical difference can be practically unimportant, statistically uncertain or inseparable from field and operational variation.
- 01Reproduce the dataset version, treatment coding, experimental units, model or statistical method, estimates, uncertainty and sensitivity checks with qualified support
- 02Compare the report with predeclared outcomes, all exclusions, protocol deviations, missing data and alternative explanations; reject unsupported causal or marketing language
- 03Publish field, season, soil, weather, management, varieties and lots, design, uncertainty, practical context and explicit limits on transfer to other farms and years

Move beyond one task into the complete evidence, technology, operating, and review sequence around it.
Build trustworthy on-farm trials and evidence
Move from a bounded farm question through defensible comparison, repeatable measurement, transparent deviations, crop-specific audit and multi-site transfer to a controlled local pilot decision.
