Application of New-Generation Growth Regulators and Topdressing Nitrogen Fertilizers Increases Improver Winter Wheat Yield and Grain Quality in South Russia

The need for effective nutrient management is crucial optimizing wheat production and increasing the plant’s ability to tolerate different environmental stresses. In this study, we assessed influence of new-generation PGRs foliar topdressing nitrogen fertilizer their interactive effects on yield quality parameters grain flour. A three-year field experiment was conducted dark chestnut soil Rostov region. We estimated effect liquid consumption rates N32 (N32), N64 (N32 + N32), N96 as well plant growth regulators (PGRs), namely, Zirkon, Silk, Albit, productivity winter Tarasovskaya 70. results experiments indicate that highest average over three years 5.34 t/ha?1 with application N32) Albit PGR. 2020, due favorable weather conditions, greatest attained at 6.27 gluten content >28% obtained when were applied. According results, using made it possible obtain “valuable” in terms quality, which suitable premium beneficial N are worthy further investigation.
