Effect of mineral fertilizers on yield and grain quality of winter wheat in the conditions of foothill plains

Sometimes there is a concept that once applying fertilizer mean there is a good harvest. But it is not. When the soil phases are found crops there is a change in the ratio of nutrients. This ratio is of great importance in the development of these elements. With the help of science - based management to form the ratio of elements in the soil, you can get the expected and high-quality harvest. The use of seeds in different varieties of winter wheat not only increases the yield, but also improves the quality of grain. When developing a mechanism for improving the quality of grain, it is necessary to take into account the genotypic characteristics of varieties. Different varieties have their own reactions due to their different needs for the nutrient medium in the soil [1–4].
