Ostapenko S. Varieties of spring triticale reaction on agrotechnical receptions of cultivation in northern Steppe of Ukraine

The objects are the spring triticale under technological agronomy approaches impact. The goal – to work out technological measures to rise triticale adaptation taking in account weather conditions variability, new varieties morphological peculiarities, their reactions on growth regulation and biological preparations. The methods are field, micro-field experiments. Results: An optimum time for planting and rate of seedling of spring triticale for seed using forage and brewing direction was established. The varieties of spring triticale reaction was certain on basic agrotechnical factors – terms of sowing, depth of wrapping of seed, norm of sowing, top-dressing of fertilizers in different doses, and also application of growth regulators. Among the probed varieties selected «Zhaivoronok» as more productive, and «Khlibodar» which has advantages in quality of corn, they are made to order in a production. Novelty: Establishment of technological agronomy approaches for spring triticale with complex biologicalpreparations using growing in the south-western part of Steppe zone of Ukraine worked out for the first time. Productivity of varieties «Khlibodar» and «Zhaivoronok» under ordering technology – 2,89-3,05 t/ha. The scientific results were tested in the production conditions in the 70 ha and implemented in the farms of the Dnipropetrovsk province. Sphere of use – Agricultural.
