However, the use of this fertilizer is limited due to its high price. An alternative to ammonium nitrate could be the fertilizer KAS-32, which is a urea-ammonia mixture. the cost of which is lower and the application costs are also lower.<br><strong>Aim<\/strong>. The research aims to determine the most efficient application of ammonium nitrate and CAS-32 fertilizer for root-zone fertilization of corn plants. The experimental variants includes: 1) control (no fertilizers); 2) ammonium nitrate (Naa) at 100 kg\/ha in physical weight applied during the 6-leaf stage + 8-leaf stage; 3) ammonium nitrate (Naa) at 100 kg\/ha during the 6-leaf stage + CAS-32 (107 kg\/ha) during the 8-leaf stage; 4) CAS-32 (107 kg\/ha) applied during both the 6-leaf and 8-leaf stages. The effectiveness of nitrogen fertilization was studied on the corn hybrid Mashuk 390 MV (FAO 390). The study was conducted in the Stavropol Krai from 2022 to 2024.<br><strong>Results<\/strong>. After double fertilization with ammonium nitrate, the plant height during the flowering phase increased by an average of 10 cm over the 2022\u20132024 period. When ammonium nitrate and CAS-32 are combined, plants grow 12 cm taller. Fertilization with CAS-32 alone resulted in an increase in plant height of 9 cm. Root-zone fertilization with ammonium nitrate at a rate of 100 kg\/ha during the 6-leaf and 8-leaf stages resulted in an average grain yield increase of 0.71 t\/ha (11.8%) over three years. The combination of ammonium nitrate applied at the 6-leaf stage and CAS-32 at the 8-leaf stage increased grain yield by an average of 0.81 t\/ha, or 13.4%. Double fertilization with liquid nitrogen fertilizer CAS-32 at the 6- and 8-leaf stages increases grain yield by an average of 0.71 t\/ha (11.8%). The lowest costs (an average of 4,535.09 rubles\/ha for 2022\u20132024) were observed when using liquid CAS-32 fertilizer at a rate of 107 kg\/ha, while the highest costs (4973.96 rubles\/ha) are associated with the application of ammonium nitrate. The highest return on investment (4754.52 rubles\/ha) was achieved with ammonium nitrate applied during the 6-leaf stage and CAS-32 during the 8-leaf stage, yielding 1.04 rubles for every ruble spent.<br><strong>Conclusions<\/strong>. Due to its high efficiency and low cost, it is recommended to fertilize corn plants during the 6-leaf stage with ammonium nitrate (Naa100 kg\/ha), followed by a second application of KAS-32 fertilizer during the 8-leaf stage with 107 kg\/ha, or alternatively, KAS-32 can be used as the sole fertilizer for both applications.<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-df03325adc83c022634de6b79d43432f wp-block-paragraph\" style=\"line-height:1.4\"><\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-56f7aa83755ebbc580e7597aa546b42d wp-block-paragraph\" style=\"line-height:1.4\"><strong><em><strong>Keywords<\/strong><\/em><\/strong><em>:<\/em> corn, fertilizers, ammonium nitrate, CAS-32, grain yield, costs, profitability<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family wp-elements-8e999d42d5f9e6baa38695ed5f3dbca6 wp-block-paragraph\" style=\"font-size:12px;line-height:1.4\"><strong><strong>For citation<\/strong>.<\/strong> Bagrintseva V.N., Ivashenenko I.N.
