Dudka N. Optimization of cultural methods of summer cabbage, cereal and leguminous cultures in joint crops for green fodder in northern Steppe of Ukraine

Object- process of optimization of methods of cultivation for complex agrocenosis (specific structure, ratio of components, rate of seeding, dozes of fertilizers, terms of harvesting). Purpose - by optimization of methods of cultivation to increase fodder efficiency of annual аgrocenosis in conditions of northern Steppe of Ukraine. Methods -field and laboratory. Results - the offered early summer mixes raise gathering of digesting protein on 18,8-45,2 % concerning barley and оats with peas, and combined agrocenosis of maize on 11,1- 68,5 % concerning one-specific crops of maize. Novelty - for the first time in conditions of the subzone is carried out the complex estimation of efficiency of spring cabbage cultures depending on methods of cultivation. The expediency of spring аgrocenosis use as predecessor of after-cutting crops on the forage and winter wheat on the grain is established. Results are introduced in farms of the Dnipropetrovsk province on the area 430 hectare. Branch - an agriculture.
