On average, over three years, the maximum yield (4,16 t / ha) and a significant increase in yield (1,10 t / ha) from the payback of 1 kg of fertilizers - 5,2 kg of grain in relation to control, provided the hybrid Guslar with the background of fertilizing in a dose of N60P60K60 in the main application and N30 in spring in nutrition. For the normal growth and development of sunflower plants, the optimal conditions for the aeration of chernozem regenerated, the volumetric mass of which varied from 1,12 to 1,27 g / cm3 in the total spatula from 50,3 to 57,23%, and aeration of aeration - 23 , 0-42,3%.
