EFFICIENCY OF APPLICATION OF POTASSIUM-SILICON FERTILIZER ON INCREASING DOSES OF NITROGEN
The conducted studies in the field experiment on the lugovo-chernozyomnoj to soil have shown that the foliar application of potassium-silicon fertilizer at the stage of 5-6 and 7-9 leaves at a dose of 1,0 l/ha on rice crops sufficiently provided with nitrogen nutrition contributed to an increase in yield by 6,9 %. The greatest productivity has made 9,85 t/hectares. Carrying out of not root top dressing is economically justified. The greatest has been conditionally-net profit received on variant N120 P55K40 + K-Si which has made 7550 rbl./hectares
