Abstract
At present, the inclusion of foliar fertilization in the technology of growing grafted grape seedlings is becoming more widely used. Economy, efficiency, undoubted benefits of fertilization and the need to reduce the pesticide load on the soil encourage the study of modern fertilizers in practical use. In the conditions of the Rostov region in 2021-2022, the inclusion of foliar fertilization with modern preparations (Fertigrain Foliar and Juss Argentum Agro) in the technology of growing grafted grape seedlings of the Sibirkovyi, Stanichnyi, Varyushkin varieties on Kober 5 BB rootstock was studied. As a result of the research, the following was established: an increase in the length of growth: from 84.0 cm to 129.0-171.7 cm in seedlings of the Sibirkovyi grape variety; from 83.0 cm to 89.7-148.0 cm in seedlings of the Stanichnyi grape variety; from 43.7 cm to 51.3-96.7 cm in seedlings of Varyushkin grape variety; increase in the ripe part of growth: from 20.7 cm to 44.7-68.3 cm in seedlings of the Sibirkovyi grape variety; from 28.7 cm to 63.3-90.3 cm in seedlings of the Stanichnyi grape variety; from 21.0 cm to 33.3-54.0 cm in seedlings of Varyushkin grape variety; increase in the diameter of annual growth: from 5.6 mm to 7.4-9.1 mm in seedlings of the Sibirkovyi grape variety; from 5.1 mm to 7.0-9.3 mm in seedlings of the Stanichnyi grape variety; from 5.0 mm to 5.1-5.9 mm in seedlings of Varyushkin grape variety; an increase in the survival rate of seedlings on the nursery garden: from 22.4 % to 37.1-51.9 % in seedlings of the Sibirkovyi grape variety; from 34.3 % to 57.1-85.7 % for seedlings of the Stanichnyi grape variety; from 27.1 % to 29.0-48.1 % in seedlings of Varyushkin grape variety; increase in the final yield of seedlings: from 19.0 % to 31.6-44.1 % for seedlings of the Sibirkovy grape variety; from 29.1 % to 48.6-72.9 % in seedlings of the Stanichnyi grape variety; from 19.8 % to 24.2-38.2 % in seedlings of Varyushkin grape variety. Key words: GRAPES, GRAFTED SEEDLING, COMPLEX FERTILIZER, BIOMETRIC INDICATORS OF DEVELOPMENT, SURVIVAL RATE, YIELD OF SEEDLINGS
