THE COMPARATIVE EVALUATION OF COMPETITIVENESS OF SPRING BARLEY FOR GRAIN GROWING TECHNOLOGIES UNDER CONDITIONS OF RIGHT-BANK FOREST STEPPE
Journal Title: Наукові доповіді НУБіП України - Year 2019, Vol 2, Issue 2
Abstract
The modern resource-saving technologies for the cultivation of spring barley are based on the effective use of hydrothermal and varietal resources and plant life factors. Therefore, the existing and improved technologies of growing spring barley should be aimed at more complete realization of the genetic potential of intensive type varieties. The direction of produced grain using and the competitiveness of the proposed technologies depend on this. We have proved the competitiveness of spring barley varieties growing technology under the conditions of the Right-Bank Forest Steppe. It is established that optimization of spring barley growing technology on the basis of balanced fertilizer system, namely the introduction of nitrogen fertilizers at a dose of N90 on the phosphoric-potassium background P45K45 and the use of plant growth regulators (Binom or Terpel) provides for the implementation of the genetic potential of Nabat and Vinnytskyi 28 varieties by 60-70%, the grain yield level of 6.39-5.78 t / ha, protein content by 13.8-13.9%, and consequently, the coefficient of integrated assessment for competitiveness is 1.09-1.04 and the extensive-intensive development direction. The obtained indicators make it possible to state that the cultivated technologies that were investigated are competitive with the corresponding quality of the products obtained, which is very important when using barley grains for feed purposes.
