Researchers tested two groups of wheat plants under identical conditions except for fertilizer application. Group A received a phosphorus-rich fertilizer, while Group B received After eight weeks, Group A showed significantly greater root development and grain yield. However, the researchers emphasized that the experiment was conducted on only one soil type. Which conclusion is most justified?
- The observed benefit may not apply to all soil types
- Phosphorus fertilizer always increases crop yield in every soil
- Soil type has no effect on fertilizer performance
- None of these
Explanation
- Since the experiment was conducted on only one soil type, the results cannot be generalized to all soils.
- The study shows phosphorus fertilizer was beneficial under the tested conditions.
- Different soil types may respond differently to the same fertilizer.
- A scientific conclusion should be limited to the evidence collected.
- More experiments on different soil types are needed before making a universal claim.
