Examination of the evapotranspiration dynamics of maize in Thornthwaite-Mather type compensation evapotranspirometer

According to the data provision of National Meteorological Service, since early 1980’s an intense warming has begun and it is also reflected in domestic observations. In Hungary, just as other Central European countries, extremes weather events are becoming more common. As a main crop, maize (sweet corn) outstanding national global significance. Certainly, changes water supply will harmfully affect cultivability too. Water stress reduces leaf surface, therefore because less captured photosyntetically active radiation, biomass production yields be reduced. Weeds with wider tolerance range than crops may become increasingly dangerous competitors field crop their wide range, fertility strong adaptability changing climate- precipitation conditions. this research effect climate change on evapotranspiration was investigated at Agrometeorological Research Station MATE Georgikon Campus Keszthely, between 21 May 2021 1 September Thornthwaite-Mather type compensation evapotranspirometer. The aim study assess characteristics (like area index, daily evapotranspiration, yield) sweetcorn under optimal Furthermore determine how weeding affects plant so half treatment (1 vessel evapotranspirometer) kept weed-free, while exposed natural weeding. terms results, positive relation temperature found been established, that maximum greater mean temperature. case yield indicators, negative statistically detectable pointed out, presence weeds can negatively quantity crops. results compared number researches subject, concluded consequences change, especially increasing frequency drought-hot periods could pose major threat successful future.
