Yield and quality of spelta grain (Tríticum spélta L.) in the conditions of the Forest Steppe of Ukraine

The article presents the results of research on peculiarities spelled yield formation and grain quality depending humate plant growth regulator use in conditions unstable moisture Forest Steppe Ukraine. purpose was to identify influence elements technology growing varieties productivity grain. During 2019–2022, conducted at experimental field educational production centre Bila Tserkva National Agrarian University. It found that studied differ biological manifestations formation, namely Zorya Ukrainy had a 5.66 t/ha, Europe – 5.89 Atterhauer Dinkel 4.85 t/ha. And according years research, best were 2021, when average 5.95 worst 2020 5.07 Better observed multi-year perspective with application Humate potassium GK-17 earing phase again milk ripeness by combining it introduction Agriflex Amino phase. Under such conditions, variety Ukraine 5.90 Europa 6.43 5.17 As for qualitative characteristics wheat grain, option using determined. nature 663 g/l, 680 758 protein content 18.55 %, 18.27 14.70 % crude gluten is 48.8 41.6 33.0 respectively. These values experiment confirmed high efficiency factors indicators Key words: wheat, variety, stimulator, humate, productivity, content, nature.
