12 claims from these papers; 1 citation between them.
Papers whose results differ, checked claim by claim 2
2 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 APPLIED COPPER ON VEGETABLE CROPS GROWN IN PRINCE EDWARD ISLAND (1983)
no changeCopper at 2 and 4 kg/ha did not increase rutabaga yields.
EFFECT OF FOLIAR AND SOIL APPLICATION OF COPPER ON THE LEVEL AND QUALITY OF WINTER RAPESEED YIELDS (2008)increaseSoil copper fertilisation at 8 and 12 kg Cu per ha significantly increased rapeseed yield relative to the no-copper control.

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.
