49 claims from these papers; 5 citations between them.
Papers whose results differ, checked claim by claim 6
6 pairs of papers on this question report results that differ: an effect in one paper, the opposite effect or no effect in the other. Two model reviewers reading both claims accepted each pair.
- The timing of exogenous 2,4-dichlorophenoxyacetate (2,4-D) application affects nodulation of soybeans,glycine max(L.) merr. (1991)
decreaseExogenous 2,4-D added at sowing considerably depressed soybean shoot and root development.

A paper is on the positive side when any of its claims here is positive. Claims are grouped by organism, treatment and what was measured or targeted. Claims that compare genotypes are left out; a claim about lacking a nutrient counts the other way round in that nutrient’s question. “Results differ” marks a question where two model reviewers, reading both claims, accepted at least one pair of papers whose results differ.
