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 2002–2019. Total maize yield and yield rate increased in the Czech Republic from 1961 to 2010, but they became to decrease after 2010. This is in line with the tendency of decreased precipitation and an increase in temperature after 2010, and changes are especially significant during the maize growing period, which indicates the importance of temperature and precipitation. In detail, there is a low to moderate negative correlation (−0.39 to −0.51) between grain maize yield and the average temperature in August for almost all the regions. While there is a low negative correlation between silage maize yield with the average temperature in July and August from some regions. The precipitation in July exhibited moderate to high positive correlation (0.54–0.79) to grain maize yield rate for almost all the regions, and it had low to moderate positive correlation (0.35–0.70) to silage maize yield rate for all the regions. Water deficit exhibited a negative correlation with both maize yield rate and its influence mainly in July for silage but both in July and August for grain. Farmer’s profit from grain maize is influence by yield rate, temperature, precipitation, and water deficit. A positive correlation was found between profit and grain yield rate and precipitation from July and August, while a negative correlation was detected between profit and water deficit and the average temperature in July and August. In conclusion, our results pointed out the factors influencing maize yield rate under changing climate conditions in the Czech Republic, and it warrants further studies on how to maintain maize production in a changing climate.

Customer Preferences for Organic Agriculture Produce in the Czech Republic: 2016 and 2019

“…Organic farming represents an alternative to the classic intensive production and it is becoming more popular among the consumers as the environmental issues are more highlighted. However, it can be an alternative also for the producers, especially under the changing climate conditions [38,39]. This can be important for countries relying on agricultural production, where organic production can offer higher added value [40].…”

Effects of Fallow Management Practices on Soil Water, Crop Yield and Water Use Efficiency in Winter Wheat Monoculture System: A Meta-Analysis

“…The fallow duration under winter wheat monoculture generally ranges from 3 months ( Wang et al, 2011 ) to 24 months ( Huang et al, 2015 ). Using the data for MAP instead of the precipitation occurred during fallow period or growing season may have led to some bias in this meta-analysis study, as wheat production is affected by not only SWSp but also water supply during growing season ( Brown and Rosenberg, 1997 ; Wang et al, 2011 ; Maitah et al, 2021 ). In Eastern United States, where the relationship between crop yield and precipitation revealed that moisture scarcity, however, herded crop yield ( Huang et al, 2015 ).…”

Maize stomatal responses against the climate change

“…Certainly, there are several works that show the relevance of these factors on maize yield in distinct parts of the world ( Table 1 ). Maitah et al (2021) , for example, demonstrated the influence of precipitation, from 2002 to 2019, on maize yield in the Czechia. They found that both total yield and yield rate increased from 1961 to 2010, but they dropped after 2010, just when precipitation also decreased.…”

“…They found that both total yield and yield rate increased from 1961 to 2010, but they dropped after 2010, just when precipitation also decreased. After 2010, there was also a trend of increasing temperature that correlates with a decrease in total yield and yield rate ( Maitah et al, 2021 ). Data from more than 20,000 historical maize trials in Africa, from 1999 to 2007, combined with daily temperature and precipitation data, showed that each additional degree day above 30°C reduced the final yield by 1% under optimal rainfed conditions, and by 1.7% under drought ones ( Lobell et al, 2011 ).…”
