Ecological plasticity and stability of common millet (Panicum miliaceum L.) productivity in different environmental conditions of Ukraine

Purpose. To estimate the ecological plasticity of common millet yield under conditions Steppe, Forest-Steppe and Forest Ukraine. Methods. Mathematical statistical: determination stability by Eberhart & Russell method, correlation analysis. Results. As a result analysis cultivated areas during period 2011–2020, it was revealed that in Ukraine depend on world ones (r = 0.34). It determined high level obtained forest-steppe zone, namely Poltava, Khmelnytskyi, Cherkasy, Sumy Kharkiv regions (2.20–2.51 t/ha). Quite rates were Vinnytsia, Kyiv (Forest-Steppe zone) Kirovohrad (Steppe (1.86–2.02 Low over 10 years noted Rivne, Zhytomyr Volyn regions, which belong to Forrest zone (1.09–1.34 is shown 2011–2015 variability observed Vinnytsia regions. The coefficient variation 42.0–71.3%. During 2016–2020 significant Donetsk, Odesa 31.8–43.9%. In from 2016 2020, trait Vinnitsa, Kyiv, Kharkiv, Khmelnitsky Sumy, Cherkasy Poltava Conclusions. According results studies, found with reduction area world, volume its production increases. hig­hest observation. yield, favorable for realization biological potential Donetsk Steppe
