Abstract

The results of research on the effect of pre-sowing treatment of seeds and plants with Vimpel-2, Oracle multicomplex, Oracle zinc separately and together in different phases of maize plants of the early hybrid DN Meotida are presented. The research was conducted by us in the field conditions of Khmelnytsky SARS IFAP NAAS of Ukraine (2018-2020). As a result of the conducted researches the following conclusions are made. The combination of pre-sowing treatment of seeds with subsequent treatment of corn crops in the early stages of development of the complex of drugs provided an increase in height of corn plants, corn plant height increased, on average over the years by 26,0 cm or 11,5%, leaf surface area by 0,075 m2 or 23,5%. All studied variants of pre-sowing seed treatment and foliar fertilization provided an increase in the number of productive cobs, compared to the control, by 2-9 pcs. or 2-9 % - on average over the years of research. All studied methods of pre-sowing seed treatment and foliar feeding of corn in the early stages of growth provided an increase, on average over the years of research, the weight of grain from 1 head of corn by 9,0-29,2 g or 7,8-25,5%, weight gain 1000 grains - by 18,0-29,3 g or 6,8-11,2% compared to the control. All studied methods of pre-sowing seed treatment and foliar feeding of maize plants in the early stages of development provided a significant increase in grain yield compared to control – 0,65-1,62 t / ha or 9,1-22,6%, on average for two years of research.
