Hozh O. Productivity of corn hybrids dependent on micronutrients and growth regulators on the irrigated lands of southern Ukraine

The object of research - the growth and development of new plant corn hybrids of different maturity groups under irrigation southern steppes of Ukraine, laws of formation of their performance in the application of growth regulators and micronutrients. The purpose of research - the study of influence of the use of complex liquid micronutrients and growth regulators on corn productivity and quality of new hybrids of different maturity groups. Research Methods - Field; laboratory; statistical; calculated. Results of research - theory for the first time in the conditions of South Steppe of Ukraine defined performance features of formation of new domestic maize hybrids FAO 180-430. A comprehensive assessment of grain quality depending on the use of new liquid complex of micronutrients and growth regulators for irrigation. To practice: For guaranteed high grain yield 10-14 t / ha of new corn hybrids for cultivation of irrigation in Southern Ukraine proposed to grow early maturing hybrid DN Pyvyha, middle-Skadovsk, middle-Kahovskij and Medium Arabat. Scope - farms south of Ukraine.
