Hlushko T. Optimization of technological methods of growing corn in the Southern Steppes of Ukraine

The object of researches is productivity of hybrids of corn of different groups of ripeness depending on the explored factors in the conditions of South Steppe of Ukraine. Purpose of researches - to optimize the technological receptions of forming of productivity and quality of corn of hybrids of corn of different groups of ripeness depending on the background of mineral feed and new complex preparations. Methods of researches - scientific, special, mathematical-statistical; computation-comparative. Results of researches - For a theory: First in the conditions of South Steppe of Ukraine the basic technological receptions of growing of new hybrids of corn of different groups of ripeness are optimized, the processes of their growth and forming of productivity and quality of corn depending on the background of feed and treatment of plants by modern preparations on irrigation are explored. For practice: For the receipt it is assured high productivity and quality of corn of new hybrids of corn of different groups of ripeness for growing of them on irrigation in the conditions of South of Ukraine, it is offered to apply the recommended dose of mineral fertilizer for providing of productivity of corn 11-14 to process t/ga plants by modern complex preparations in a phase 7-9 sheets, that provides high recoupment, economic and power efficiency of the noted measures. The sphere of the use is the agricultural enterprises of south of Ukraine.
