Zavertalyuk O. Formation of yield capacity of sugar and bursting corn depending on sowing time and methods of weeds controlling in the Northern Steppe of Ukraine.

Object of research: peculiarities of yield corn sugar and corn rozlusnoyi depending on sowing time and measures of controlling weed-infested crops Objective: To establish a new reaction of corn sugar and rozlusnoyi for sowing, application of herbicides and to develop effective measures to control the weed-infested crops conditions for the Northern Steppe of Ukraine. Scientific novelty: the first time the characteristics of growth, plant development, yield formation of corn sugar and corn rozlusnoyi depending on sowing time, measures controlling weed-infested crops. Research results: Identified reaction corn sugar and rozlusnoyi the effect of herbicides with different doses of application, and the residual amount of herbicides in grain milky stage corn sugar. Established and economically reasonable practices, weed-infested control in maize crops of sugar and rozlusnoyi. Developed and recommended production processing methods of growing corn sugar and corn rozlusnoyi, providing increased yields respectively 1.33 and 0.83 t / ha, profitability by 69 and 187%.
