Ruban V. Productivity of the corn hybrids depending on density standing of plants and mineral nutrition at drop irrigation

Object of researches - the Technological process of growing in the conditions of south of Ukraine corns of corn depending on hybrid composition, densities of standing of plants and background of nitric feed at the tiny method of watering. The purpose of researches is the ground of elements of technology of growing of different after the groups of ripeness of hybrids of corn depending on density of standing of plants and doses of nitric fertilizers at the tiny method of watering in the conditions of south of Ukraine. Methods of researches - the field and laboratory; biochemical; thermostat - gravimetric; statistical; computation-comparative. Results of researches - For a theory: First for the terms of south of Ukraine on a livery middling to suglinkovoy soil the processes of forming of productivity of plants of corn depending on hybrid composition are explored, densities of standing of plants and background of nitric feed for the use of tiny irrigation. Conformity to the law of growth is set, development and dynamics of forming of productivity of plants of corn depending on hybrid composition, densities of standing of plants and doses of nitric fertilizers. For practice: On results the conducted researches the scientific-grounded recommendations from technology of growing of corn at the tiny method of irrigation are offered. The offered by an author elements of technology of growing provide the receipt of productivity of corn of corn at the level of 16-18 t/ga, high level of economic and power efficiency. The sphere of the use is the agricultural enterprises of south of Ukraine.
