Abstract: The purpose of research is to study the effectiveness of foliar fertilization when growing grafted grape seedlings on a nursery garden in the conditions of the Rostov Region. The studies were carried out at the production complex and experimental field of ARRIV&W (a branch of FSBSI FRARC) located in Novocherkassk. The study examined the inclusion of foliar application of modern complex fertilizers of the following names: Bio-Don 10 Fe (0.2 %); Beres (0.05 %); Juss Argentum Agro (0.2 %); Helios Boron Molybdenum (0.3 %); Nano Silicon (0.06 %); Fertigrain Foliar (0.2 %) in the technology of growing grafted seedlings of the technical white grape variety Sibirkovy (rootstock Kober 5 BB). The development of the main biometric indicators of the annual growth of the experimental variants using fertilizers increased significantly in comparison with the variant without additional treatments (control) by: 45.0–189.7 cm along the total length of the increase (LSD05=32.84); 23.7-104.7 cm along the length of the hardwood part (LSD05=15.46); 2.7–29.4 % on aging (LSD05= 6.37); 0.2-4.0 mm in diameter (LSD05=0.75); 693.1-5101.5 cm2 of the leaf surface area (LSD05=630.76). The survival rate in the control was 22.4%, and when using fertilizers, it increased to 32.4–51.9 %, which is significant for LSD05 = 1.4. The yield of seedlings in the control was the lowest (19.0%), non-root treatment increased the bottom indicator to 27.5–44.1 %, which is significant at LSD05= 1.31. An increase in the multiplicity of foliar fertilization (Bio-Don 10 Fe; Beres; Helios Boron Molybdenum; Nano Silicon; Fertigrain Foliar) from 2 to 4 times increased the survival rate by 1.4–14.8 %, and the yield of seedlings by 1.2–12.5 %. Correlation analysis showed positive linear dependencies: 1 – increase in the diameter of the increment with an increase in the multiplicity of processing (r=0.589); 2 – increase in survival rate and yield of seedlings with an increase in the frequency of processing (r = 0.659).
