On-Farm Treatment
Trial Design Assurance

A side-by-side field strip can be useful observation, but it is not automatically a fair treatment comparison. Trial design makes the question, treatment, experimental unit, comparison, field variation, assignment, replication, measurement and analysis plan visible before machinery and season make corrections impossible.

HOW TO READ THIS PAGE

Visual explanationA diagram or operating scene makes the relationship visible.

Structured modelA flow, comparison, capability set, or boundary map organizes the idea.

Guided explanationOriginal prose connects the concept to its operating context.

This route describes the briefing's editorial structure. It is not an implementation sequence, maturity score, compatibility claim, or field recommendation.
01 / Overview

Design the comparison
before applying treatments.

SARE materials introduce comparison, replication, randomization and blocking as core on-farm research concepts while emphasizing practical field constraints and appropriate expertise.

The experimental unit is the independently assigned unit—not automatically every sensor reading, plant or yield-monitor cell. Confusing observation count with independent replication can make evidence appear stronger than the design supports.

02 / Design chain

Move from a clear question
to an executable protocol.

01QUESTION / 01Define the claimFarm decision, population and season, treatment and comparator, primary outcome and timing, practical importance, hypothesis, exclusions and decision authority
02UNIT / 02Choose the experimental unitIndependently assignable field area, pen, group, facility or other unit; interference, carryover, buffers, field gradients, machinery dimensions and operational feasibility
03ASSIGN / 03Build a defensible comparisonDesign and blocking rationale, assignment method, replication, controls, treatment identity, concealment where feasible, protocol map and prohibited mid-trial changes
04ANALYZE / 04Predefine interpretationPrimary unit and outcome, analysis matched to design, missing and excluded units, uncertainty, multiple outcomes, deviations, sensitivity, practical relevance and transfer boundary
Read left to right as an explanatory evidence path. Arrows do not encode a protocol, automatic control sequence, compatibility claim, or operating instruction.
03 / Validity threats

Visible field differences
can imitate treatment effects.

ThreatExampleDesign response
SelectionOne treatment receives the historically stronger areaRandom assignment or justified allocation with limits
Spatial trendSlope, soil or drainage changes across treatmentsBlocking, orientation and mapped context
InterferenceWater, spray, pests or traffic cross unit boundariesBuffers and explicit spillover review
Pseudo-replicationMany readings come from one assigned stripAnalyze the true independent unit
04 / Practice

Keep design and execution
in one evidence record.

MAP

Freeze a treatment map

Preserve unit identities, boundaries, assignment, treatment, comparator, buffers, excluded areas, machinery passes and field context before execution.

LOCK

Name the primary outcome

Distinguish the primary decision measure from exploratory observations and specify timing, method, units and experimental-unit aggregation.

DEV

Record deviations

Keep weather, missed passes, equipment changes, overlaps, contamination, replanting, animal movement and protocol edits visible without silently deleting inconvenient units.

HELP

Match expertise to complexity

Use qualified statistical and domain support when designs, interactions, repeated measures, spatial dependence or analysis exceed the farm team's competence.

05 / Boundaries

A design briefing is not
a trial prescription.

No treatment, plot size, replication count, design, statistical test or sample-size recommendation is provided.Use qualified local research and domain professionals with the exact question, field, subjects and constraints.

Randomization and replication do not repair poor measurements or protocol noncompliance.Measurement quality, execution, exclusions, analysis and interpretation remain independent evidence layers.

Trials involving pesticides, animals, people, food, machinery or regulated activities require additional authority.Follow applicable labels, welfare, safety, ethics, legal and institutional requirements.
