Wheat (Triticum aestivum) is one of the most important agricultural crops, used for human nutrition, animal feeding and as industrial raw material. High crop yields of wheat appear the guarantee of national food security and public welfare. The most effective method of crop yield increase is the development of plant stress resistance due to application of special chemical and biological preparations with physiologic activity (humates, complex preparation and bio-preparations). According to above mentioned, the main goal of the research is evaluation of the influence of mineral fertilizers, complex preparations with micro elements and growth regulators on productivity and seed quality of different varieties of spring wheat in the conditions of North-West zone of the Republic of Belarus. It is established that a variety of Tom is the most responsive to increasing doses of mineral fertilizers with N65P60K90+N25UAN to N75P70K120+N25UAN+N20, where the observed increase in grain yield of 5.4 t/ha of crude protein in the grain by 2.2%. The best option is the use of fertilizer Fiovital against N65P60K90+N25UAN, where the yield is 49.0 t/ha and crude protein content of 15.1%. Grade Sabine provides a higher grain yield if compared with a grade Tom. The highest grain yield and crude protein content obtained in the form N65P60K90+N25UAN+Fitovital – 54.0 t/ha and 14%.
