APPLICATION OF PLANT GROWTH REGULATORS ON CORN CROPS IN THE SOUTHERN STEPPE OF UKRAINE
Keywords:
corn, biostimulants, plant density, fertilization, productivity
Abstract
The aim of the research was to determine the productivity of the Ingulsky corn hybrid of the medium-ripening group of maturity depending on seed and plant treatment during the growing season when applying Regoplant and Vermystym biostimulants, as well as the effect of a plant density in different moisture conditions. Methods. The field laboratory and mathematical and statistical methods were used in the course of the research. Results. Irrigation provided an increase in the yield of silage mass by 1,4-2,2 times. Thus, on average, over three years, the highest productivity of corn for silage was observed when having a plant density of 90 thousand/ha without applying biostimulants – 48,6 t/ha and with applying biostimulants – 59,3-64,7 t/ha. The highest dry matter yield of 17,3-18,5 t/ha, feed unit yield of 16,1-17,4 t/ha and digestible protein content of 0,75-0,82 t/ha was obtained when biostimulants were applied when having a plant density of 90 thousand/ha. It was found that in non-irrigated conditions, the highest grain yield was 3,1-4,7 t/ha on the variant with a plant density of 30 thousand/ha. Applying Regoplant biostimulant provided an increase in grain yield by 1,6 t/ha, while applying Vermystym biostimulant provided an increase in grain yield by 1,2 t/ha, respectively. Conclusions. In non-irrigated conditions, it is necessary to apply Vermystym biostimulant with a sowing rate of 70 thousand/ha to obtain the highest yield of fodder units of 9,6 t/ha and 0,42 t/ha of digestible protein content from corn green mass. In irrigated conditions, the seeding rate should be increased to 90 thousand/ha and Regoplant biostimulant should be used to obtain the highest yield of feed units of 17,4 t/ha and 0,87 t/ha of digestible protein content. The cultivation of the Ingulsky hybrid corn for grain in non-irrigated conditions provided the highest yield of 4,7 t/ha with a plant density of 30 thousand/ha and applying Regoplant biostimulant. In irrigated conditions increasing a plant density to 70 thousand/ha and applying Regoplant biostimulant provided the maximum yield of 11,2 t/ha.
