Influence of precipitation and temperature on maize production in the Czech Republic from 2002 to 2019

Abstract Maize is one of the important food crops in the Czech Republic, its growth and productivity are influenced by climate change. This study investigated the influence of precipitation under recent climate change on maize yield both for grain and silage in the whole Czech Republic during 2002–2...
