Other claims from this paper (8)
- Association Wheat yield variability correlated positively with 9-month SPEI.
- Observation Wheat yield sensitivity to medium and long drought declined over three decades.
- Association SWC explained 38.9 ± 3.2% of short-term SSPEI variability.
- Association SWC, CO2 and Nfer jointly accounted for 84.0 ± 6.2% of long-term SSPEI variation.
- Association Nitrogen fertilizer enhanced sensitivity during prolonged drought.
- Association CO2 enrichment decreased sensitivity in long-term drought.
- Association CO2 enrichment increased yield reductions during short-term drought.
- Recommendation Water conservation and fertilizer practices should vary with drought episode.
