The soil and climatic conditions of Azerbaijan, located in nine climatic zones, allow to plant fodder beet several times in a row in all zones and get a rich harvest. Fodder beet is a very demanding plant and gives high yields when planted in fertile soils. The article examines the importance of growth regulators, which are important in the life of agricultural crops, and the effect of Nano-Gro (made in USA) growth substance on fodder beet as the first application of nanotechnology to agriculture in our country. Living organisms contain substances in such small doses that even when they are not present in sufficient amounts in the diet, serious diseases can sometimes result in death. These substances are not nutrients, but they contain microelements that affect the physiologically active points in the meristem of all plants and regulate their vital functions, either accelerating or weakening plant growth. Wor-ld research also shows that seeds, twigs and seedlings are soaked with all nutrients, fertilized and sprinkled with green mass. Nano-Gro, a growth regulator used in the study, contains Fe, Al, Ni, Mn, Mg, Ag sulfate compounds and sucrose, and weighs 0.05 grams. The purpose was study of the application of different fertilizer norms and the effect of various norms and proportions of physiological active Nano-Gro substances on fodder beet yields and biometric indicators. Field experiments were laid out in the territory of Absheron Subsidiary Farm (fodder) of the Research Institute of Crop husbandry in 2014-2016. A 2-factor field experiment was carried out using the “Semi-sugar white beet” variety. Field experiments were laid out in 4 replications, 6 options, 2 schemes, the sowing norm was 14 kg per hectare in the sowin area of 70 x 30 cm. The predecessor was a mixed sowing of legumes and cereals.
