Abstract
The economic evaluation of the efficiency of mineral fertilizers at the cultivation of spring triticale on sod-podzolic light loamy soil (Podzoluvisol) with different content of exchangeable magnesium in the soil was carried out. It was found on control plots without fertilizers the yield increased on 35 % in the limits of Mg content 46-147 mg/kg of soil. Further increase of Mg content in soil up to 198 mg/kg was excessive; it followed by reduction of grain yield on 10 %. Maximal yield response to basic NPK treatment and response to foliar spray of Mg fertilizer was noted on low and medium content of exchangeable Mg 46-92 mg/kg in soil with total net return of 76 USD/ha. Efficiency of NPK and Mg fertilizers were strongly reduced on the plots with high level of soil Mg supply.
