The effect of Azotophyt and organic balance biological preparations on the productivity of the P64F66 sunflower hybrid under the conditions of the North-Eastern Forest-Steppe of Ukraine was investigated. It was found that foliar application of the preparations at the 2-3 pair leaf stage increased seed yield compared with the control treatment. The highest seed yield (3.55 t ha^-1) was obtained using organic balance, confirming the potential of biological preparations for sustainable sunflower cultivation.
