Abstract: Increasing drought and extreme rainfall are major threats to maize production in the United States. However, compared to drought impact, the impact of excessive rainfall on crop yield remains unresolved. Here, we present observational evidence from crop yield and insurance data that excessive rainfall can reduce maize yield up to −34% (−17 ± 3% on average) in the United States relative to the expected yield from the long‐term trend, comparable to the up to −37% loss by extreme drought (−32 ± 2% on average) fro… Show more

“…Most variables exhibit expected behaviors. The response curve of rainfall suggests that both drought conditions and excessive rainfall are harmful to yield (Lobell et al 2014, Li et al 2019a. High maximum temperature of July harms yield, especially when it exceeds 33.5 ºC.…”

“…Importantly, where sufficient observed yield data exist, statistical models may provide additional information about yield sensitivity to climate due to their ability to account for the effects of unobserved farmer management practices or indirect weather-related drivers of yield losses that cannot be simulated by process-based models (e.g. mechanical damage by hail or wind, pests, diseases, extreme rainfall etc) (Roberts et al 2017, Li et al 2019.…”

“…Conversely, well-irrigated fields show little sensitivity to high atmospheric temperature 8,12,[15][16][17] . A further complication is that excess precipitation can cause yield damage through waterlogging, increased pests and fungal pathogens, and loss of nitrogen fertilizer 14,22,24 . Insurance data over the US suggest that maize yield damage associated with excessive precipitation is of the same magnitude as that associated with drought conditions 24 .…”
