Winter wheat is an important food crop, the demand for grain of which is growing from year to year. The problem of increasing the yield and quality of wheat grain is very acute. Currently, many methods and preventions are being involved in order to improve the technologies for growing this crop and further protection against harmful organisms, in particular, diseases. Efficient, affordable and largely environmentally friendly among these include agrotechnical approaches, in particular the use of biologized fertilizer systems.
The article presents the results of studies of the influence of biologized fertilizer systems on the development of the most common diseases of winter wheat and its productivity. The purpose of the work was to study the features of the influence of biologized fertilizer systems on the development of winter wheat diseases and its yield. To achieve this, the following were carried out: accounting of the development of the main diseases of winter wheat, analysis of the elements of the structure and levels of the yield of specified crop. During the growing season, winter wheat crops were most affected by powdery mildew (Erysiphe graminis), leaf septoria (Septoria tritici) and root decay Ophiobolus graminis Dresh.
It has been established, that the use of biologized fertilizer systems based on pea straw + N90P60K60 and the simultaneous apply of bioeffectors (BS or BS + HF) contributed to the increase of the grain productivity of winter wheat plants and the deterioration of conditions for the development of diseases, and therefore they are promising from an ecological point of view vision. Treatment of winter wheat crops with chelated fertilizer (CF) limited the development of powdery mildew and plant septoria. The application of an increased dose of mineral fertilizers (N150Р120К120) on the background of pea straw + HF provided an increase in the yield of winter wheat and a deterioration in the phytopathogenic state of agrocenosis, namely, it increased the development of the main studied diseases of winter wheat. To limit the phytopathogenic load on plants, this “recipe” can be improved by applying a chelated fertilizer.
