| Abstract | Sunflower and corn are among the most profitable crops in Ukrainian agricultural production. The main issue remains increasing the productivity of crops while realizing the genetic potential of hybrids in terms of yield and grain quality while improving growing technology, in particular, providing plants with nutrients during a certain period of their ontogenetic development. The goal of the research was to test the effectiveness of the improved technology of growing crops and increase the productivity of hybrids of sunflower and corn by realizing the genetic potential of the samples using foliar nutrition of plants with the preparations of «Vitera Ukraine» LLC in the Southern Forest Steppe of Ukraine. In the process of research, it was confirmed that without a sufficient balanced amount of nutrients, it is impossible to fully reveal the genetic potential of the plant and to maximize the biological yield of agricultural crops. The effective use of products of "Vitera Ukraine" LLC in the technological scheme of sunflower and corn cultivation to increase the productivity of crops in the Southern Forest Steppe of Ukraine has been established. To realize the genetic potential of sunflower hybrids, it is advisable to treat the seeds with Raykat Start at the rate of 2.0 l/t, in the phase of BBCH 13–14 (3–5th leaf) – to apply Raykat Growth (0.6 l/ha) and Aminocat 30 (0.4 l/ha), in BBCH 17–18 (7–8th leaf) – Nutrivant Plus Oil (2.0 kg/ha) and Ikar Bo-Mo (0.5 l/ ha), and in BBCH 50 – Nutrivant Plus Oil (2.0 kg/ha), Ikar Boron-Molybdenum (0.5 l/ha) and Brandt Converge CRN 28-0-0 (1.0 l/ha). To increase the productivity of corn hybrids, it is recommended to apply Microcut Zn–Mn (0.5 l/ha) and Aminocat 30 (0.5 l/ha) in BBCH 13–14, and in BBCH 16–18 Brandt Converge CRN 28-0-0 (2.0 l/ha) and Fitomare (1.0 l/ha). | ||
