Abstract

According to the research it was found that
fertilizers’ application on sunflower crops caused
the cost reduction of nitrogen and potassium per unit
yield formation. Application of N30P30K30 results
reducing of nitrogen’s consumption to 0,9 kg/ha and
potassium to 6,1 kg/t. Application of N60P60K60
reduced the use of nitrogen to 0,9 kg/ha and
potassium – to 8,8 kg/ton, compared with the
control. Use of phosphorus were unchanged.
