PRODUCTIVITY AND ECONOMIC EFFICIENCY OF SPRING FALSE FLAX DEPENDING ON FERTILIZERS RATES IN THE CONDITIONS OF THE WESTERN FOREST-STEPPE

In the western Forest Steppe, the influence of fertilizers on false flax yield on dark grey soils was studied. It is determined, that yield of false-flax variety Mirage under fertilizers influenced increased from 1.28 t/ha on the variant without fertilizers up to 2.44 t/ha on the variant with N₁₂₀R₆₀K₁₂₀, application, increased by 1.16 t/ha, or by 90.1%. It is shown,that the increase application of fertilizers led to higher expenses from 7376 UAN on control up to 14.312 UAN for N₁₂₀R₆₀K₁₂₀. It should be noted, that in spite of considerable increase of expenses, that highest net profit (22.288 UAN pe 1 hectare) was obtained applying high rates – N₁₂₀R₆₀K₁₂₀.
