Claim by claim

In a 60-day greenhouse pot experiment, single and dual inoculation with rhizobia and arbuscular mycorrhizal fungi significantly affected growth parameters of faba and haricot beans in saline-sodic soils (P≤0.05).
SupportedLaboratory studyLaboratory study. Shown under laboratory conditions, not in the field.
“Agronomic parameters revealed that single and double inoculation had a substantial (P≤ 0.05) effect on all treatments.”
The abstract confirms that in a 60-day greenhouse pot experiment on faba and haricot beans in saline-sodic soils, single and double bioinoculation had a statistically substantial (P≤0.05) effect across treatments.

The tallest plants were recorded with organic matter amendment combined with dual inoculation (R+M).
Partially supportedLaboratory studyLaboratory study. Shown under laboratory conditions, not in the field.
“The OM treatment and double inoculation (R+M) resulted in the tallest plants.”
The abstract states that the OM treatment and double inoculation (R+M) resulted in the tallest plants, but it does not clearly state that this occurred as a single combined treatment rather than two separate treatments.

For the sodic Alage soil, faba bean measurements were highest under R+M+50% NPSB; for the saline Ziway soil, OM+25% NPSB and R+50% NPSB were best for faba bean, while organic matter alone and R+M+25% NPSB were best for haricot bean.
Partially supportedLaboratory studyLaboratory study. Shown under laboratory conditions, not in the field.
“For the sodic soils of Alage, faba bean measurements were higher in the R+M+50%NPSB treatment followed by haricot bean. The optimum results for the saline Ziway soils were obtained with OM+25%NPSB and R+50%NPSB in the faba bean, while single OM treatment and R +M+25%NPSB achieved better results for haricot beans.”
The claim converts comparative findings ('higher' and 'better results') into superlatives ('highest' and 'best').

The study reports growth, nodulation and nutrient uptake after 60 days; no grain yield or field data are reported, and the authors call for field trials to corroborate the greenhouse results.
Partially supportedLaboratory studyLaboratory study. Shown under laboratory conditions, not in the field.
“Finally, for long-term agricultural productivity on the test soils, organic matter and single and dual bioinoculants are recommended, with additional field trials to corroborate greenhouse results”
While the abstract reports measurements of growth, nodulation, and nutrient uptake after 60 days in a greenhouse pot experiment and calls for corroborating field trials, it does not explicitly state that no grain yield or field data were reported.

In a separate field experiment on acidic soil, coffee husk biochar combined with NPSB fertilizer increased bread wheat grain yield, with the highest yield at 5 t/ha biochar plus 100 kg/ha NPSB under limed conditions.
SupportedField trialField trial
“The results indicated that the interaction between coffee husk biochar and NPSB fertilizer significantly increased grain yield. The highest grain yield (3.59 t ha -1 ) was obtained from the application of 5 t ha -1 coffee husk biochar combined with 100 kg ha -1 NPSB fertilizer under limed conditions.”
The claim accurately describes the findings of the field experiment on acidic soil.

In a single-season sweet potato trial, NPSB fertilizer and cattle manure acted additively rather than synergistically.
SupportedField trialField trial
“Both NPSB (estimate = 0.062, P < 0.001) and cattle manure (estimate = 0.401, P < 0.001) showed significant positive effects, with additive rather than synergistic interaction ( P = 0.972).”
The single-season trial on sweet potato found that NPSB fertilizer and cattle manure had an additive rather than synergistic interaction.

What this does and does not prove

It proves that every DOI cited resolves to a real registered work whose returned DOI matches the one requested, that none of them is retracted, and that each claim has a named sentence in a cited abstract behind it.

It does not prove that the paper as a whole supports the claim. An abstract can overstate its own findings, and a sentence can be read out of context. That is why the quote is printed here rather than summarised: if the check is wrong, you can see that it is wrong.

Evidence grading is automatic and conservative. Anything it cannot classify is marked unclassified rather than flattered upward.
