Konoplyova Y. Peculiarities of forming the grain quality of winter wheat depending on the agrotechnical receptions of growing in northern Steppe of Ukraine.

The object of research – the features of growth and development of winter wheat varieties, the quality and productivity of grain depending on weather conditions and agrotechnical measures of cultivation. The purpose - to define the most effective agrotechnical measures for cultivation of winter wheat with improved quality of grain. The methods: field, laboratory, calculated, mathematical (dispersive and correlation). The results: The agrotechnical methods of cultivation of winter wheat varieties are developed, which provide increase of productivity of grain with the improved quality in northern Steppe of Ukraine. An industrial check was carried out in farm "Forward-agro" in the Dnipropetrovs’k district of the Dnipropetrovs’k oblast’ on the area of 96 hectares. Introduction of the concluded scientific work was carried out in the Limited Liability Company "Lyubymivka" in the Dniropetrovs’k district of the Dnipropetrovs’k oblast’ on the area of 1500 hectares. The novelty - for the first time in the conditions of northern Steppe of Ukraine agrobiological features of growth and development of modern winter wheat varieties, their productivity and quality of grain depending on weather conditions and technological methods, including top dressing of sowings by complex fertilizer ecolist multicomponent and carrying out of actions for restriction of injuriousness of a wheat bug are ascertained. The efficacy of agrotechnical methods of cultivation of winter wheat variety Pysanka on different backgrounds of mineral nutrition after barley summer is defined. The scientific proposition concerning mutuality of losses of size of productivity and quality of grain in connection with duration of dead-ripe stage of winter wheat varieties Zemliachka Odes’ka, Zolotokolosa and Apogei Luhans’kyi has received the further development. The branch - agriculture.
