Peculiarities of corn yield formation depending on the influence of elements of growing technology

Purpose. To establish indicators of corn yield depending on agro-technological measures in the South-Steppe region of Ukraine. Methods. Field and laboratory research methods and statistical methods – descriptive statistics and analysis of variance. Results. The most favorable weather conditions to ensure a high level of yield were in 2018, when the average experiment was obtained 5.96 t/ha of corn, and in 2019 the yield was 5.09 t/ha. It was found that with foliar feeding of corn plants with urea 14 kg/ha + Aminomax 1 l/ha, the protein content in corn grain was 9.9–10.3%. But with foliar fertilization of plants with urea 14 kg/ha + Aidamine complex 2 l/ha protein content in corn grain was 10.1–10.7%, and the use of the destructor “StimOrganic” 2 l/ha and urease inhibitor Stabiluren (Stabiluren 30) did not significantly affect the formation of protein content. The maximum starch content was with the use of the destructor “StimOrganic” 2 l/ha and urease inhibitor Stabiluren (Stabiluren 30) in combination with Aminomax or Aidamine complex. Thus, for foliar feeding of Aminomax 1 l/ha the starch content was 73.6%, but for the use of Aidoma complex 2 l/ha – 73.8%, respectively. Conclusions. The applied factors had a positive effect on the formation of its yield and according to the variants of the experiment it was determined that the use of the destroyer “StimOrganic” 2 l/ha and urease inhibitor Stabiluren (Stabiluren 30) and the use of Aminomax 1 l/ha yielded 6.16 t/ha, but for similar experiments and fertilization Aidamin complex 2 l/ha formed a yield level on average over the years – 6.34 t/ha, respectively.
