Abstract

In the Precarpathians spring wheat can be a valuable crop for replanting destructed winter wheat sowings. Its grain is of high baking and cereal quality. In recent years, domestic and foreign researchers have bred a number of varieties that provide high and stable yields of grain. However, in the Precarpathians spring wheat is poorly distributed. It is explained by its low grain productivity due to the lack of scientifically-grounded cultivation technology. In our opinion, the main technological methods aimed to increase the yield of spring wheat varieties are selection of intensive varieties and determination of sowing terms and seeding rates that are the most suitable for this zone. Spring wheat varieties are characterized by a high ability to absorb nutrients from organic and mineral fertilizers, soil, physiologically balanced system of absorption, transportation and metabolism of ions, high resistance to changes in abiotic and anthropogenic stress factors, stable internal environment despite external fluctuations if the fluctuations are compatible with life, high energy efficiency ratio. The aim of our research was to improve technological methods of cultivation of zoned spring wheat (Struna Myronivska, Elegia Myronivska) with the yield of 4-5 t/ha of high baking quality grain in conditions of the Precarpathians. The results of studies on the impact of the biological characteristics of the variety, sowing terms and seeding rates on the structural performance of spring wheat crop (Triticum aestivum) under conditions the Precarpathians are highlighted. In conditions of the Precarpathians the highest yield of spring wheat is provided by the early sowing term (April 5) and seed rate of 6.5 million seed /ha. Elegia Myronivska variety proved to be productive. Ref. 4 titles.
