EFFICIENCY OF FOLIAR ADDITIONAL FERTILIZING OF CORN WITH FERTILIZERS OF BRAND BATR
N 2018-2020 the researchers at the All-Russian Research Scientific I nstitute of Corn studied the effectiveness of foliar additional fertilizing of corn plants in the phase of 7-8 leaves with organic and mineral fertilizer Batr 40 Nitrogen (3.0 l/ha), Batr Max (1.0 l/ha), as well as microfertilizer Batr Zinc (1.0 l/ha) in comparison with calurea (carbamide) at a dose of N10. Corn extranutrition with fertilizers had a positive effect on the growth of plants, contributed to an increase in their height. On average, over 3 years, the increase in the yield of green mass of the hybrid Mashuk 220 MV from the fertilizer Batr 40 Nitrogen was 6.85 t/ha, from the fertilizer Batr Max 4.88 t/ha. On average for 2019-2020 the increase in the yield of green mass of corn from fertilizing with fertilizer Batr 40 Nitrogen was 8.19 t/ha, Batr Max - 6.89 t/ha, Batr Zinc - 6.92 t/ha. Spraying corn with fertilizers Batr 40 Nitrogen, Batr Max and Batr Zinc provided an increase in the length of the ears, the number of grains on the cob and their weight. Foliar additional fertilizing of plants with fertilizers Batr 40 Nitrogen, Batr Max gave significant increases in grain yield, which averaged 0.43 and 0.44 t/ha for 2018-2020. The combined use of these fertilizers did not result in a greater yield increase. Microfertilizer Batr Zinc on average for 2019-2020 increased grain yield by 0.73 t/ha, while the increments from fertilizers Batr 40 Nitrogen and Batr Max for the same years were 0.30 and 0.39 t/ha, respectively. Compared with the use of fertilizers for foliar additional fertilizing with Batr 40 Nitrogen (3.0 l/ha), Batr Max (1.0 l/ha) and Batr Zinc (1.0 l/ha) spraying corn in the phase of 7-8 leaves with calurea at a dose of N10 is less effective.
