32 claims from these papers; 5 citations between them.
Papers whose results differ, checked claim by claim 4
4 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.
- Effect of silicon on the morphology of shoots and roots of alfalfa (Medicago sativa) (2006)
increaseSilicon increased alfalfa root volume, secondary-root number and root biomass.
Silicon‐induced root nodulation and synthesis of essential amino acids in a legume is associated with higher herbivore abundance (2017)no changeSilicon uptake did not affect root growth.

Papers reporting a negative result or no effect 1
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.
