Demyanchuk A. Efficiency and fodder value of corn hybrids depending on terms of sowing and outroot top dressing in the conditions of right-bank Forest-Steppe of Ukraine

The object of research - crops of corn hybrids during formation of their productivity in dependence on time of a sowing and top dressing in conditions of the right-bank Forest steppe of Ukraine. The purpose - to establish influence of a sowing and a outroot top dressing on formation of productivity and quality of corn hybrids of different ripeness groups in conditions of the right-bank Forest steppe of Ukraine. The methods of research - field, laboratory, chemical, settlement, statistical, rather - settlement. In conditions of the right-bank Forest steppe of Ukraine dependence formation of productivity of corn hybrids of different ripeness groups (Zoren, Bogun, Meteor) on a sowing and a foliar top dressing by microfertilizers. Directions of improvement processes of formation corn productivity in technology in dependence on conditions of cultivation are theoretically and practically proved. Correlation dependences between hydrothermal conditions and productivity, and also between elements of technologyof cultivation and productivity of plants are established. An economic and relative power evaluation of elements of technology of cultivation of corn hybrids are carried out. Scientific developments into economies of area Tetiivskiy region of the Kiev district on the area 180 gа are entered. Sphere of using - agricultural production.
