Primes¶
- Blocking (In Experimental Design)
- T6 — Feasible block definition versus theoretical nuisance-factor purity. In practice, blocking variables are often crude proxies for the underlying nuisance factor — e.g., geographic region as a proxy for soil heterogeneity, age-stratum as a proxy for physiological developmental stage
This sourceEarly crop-variation analysis using geographic/field structure as a (crude) proxy for soil heterogeneity, an antecedent of ANOVA-based blocking.

- Factorial Design
- T2 — Additive-effect simplification versus interaction complexity. OFAT studies are conceptually simple and easy to explain, but rely on an additivity assumption that is often wrong in nonlinear systems
This sourceThe first analysis-of-variance / variety-by-manure interaction study, demonstrating that variety effects are not additive with manurial response — the empirical basis for the claim that OFAT's additivity assumption fails in nonlinear systems.
Supported in partVerified against the publisher's abstract
The abstract raises variety-by-manure response differences as a hypothesis, which is background for non-additivity but does not state the result or discuss OFAT.
“differ not only in their suitability to different climatic and soil conditions, but in their response to different manures”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
