EFFECT OF RATES AND PROPORTIONS OF MINERAL FERTILIZERS ON THE QUALITY OF WINTER WHEAT GRAIN

Abstract

The article highlights the dependence of the quality of winter wheat grain on the use of fertilizers. The use of mineral fertilizers in different norms and ratios contributed to an increase in grain quality. The nature of the grain is 22-32 g/l higher than the control when mineral fertilizers (N210P105K70) are given in the norm, the vitreousness is 7.5% higher than the control when the mineral fertilizers are increased (P120K80) in the norm, the weight of 1000 grains is higher than the control variant (P120K80) with an increase in the norm increased to 6.6 - 8.6 g, the amount of protein increased by 1.0% compared to the control when mineral fertilizers (N210P105K70) were given in the increased rate, the amount of gluten increased by 5.4 - 6.2% compared to the control in the options with increased rates of phosphorus and potassium fertilizers high, the GDM indicator (N210P105K70) was 95.1 when given in the norm.
