Abstract. In 2021–2023, in the forest-steppe zone of North Ossetia-Alania, research was carried out on the use of a growth regulator – “Bigus VR” and complex fertilizers “Nutrivant Plyus”, “Ul’tramag Kombi” on winter wheat of different varieties Bagrat and Alekseich. The purpose of the study is to increase the yield of winter wheat with high quality indicators of food grain through the use of biopreparations and mineral fertilizers. Scientific novelty is to achieve the goal, a comparative analysis of the morphological parameters of winter wheat was carried out depending on the influence of a growth regulator and complex fertilizers. Methods. On carbonate-chestnut soils of the steppe zone of North Ossetia-Alania, Mozdok region, under rainfed conditions, experiments were carried out on two varieties of winter wheat, Bagrat and Alekseich. Results. As a result of the research, it was revealed that the growth regulator and complex fertilizers used have a positive effect when cultivating winter wheat. It was revealed that during the period of spring development, the height of plants of the studied varieties of winter wheat ranged from 21.6–27.3 cm, during the booting phase – 38.4–52.7 cm, during the heading phase - 62.4-74.7 cm, and in milk ripeness – 66.5–75.1 cm. For the Alekseich variety in the control variant, the yield was 3.79 t/ha, with the addition of the growth regulator Bigus – 4.43 t/ha and the complex fertilizer “Ul’tramag Kombi” – 4.47 t/ha. The maximum values for grain yield were noted for both studied varieties using the complex fertilizer “Nutrivant Plyus”, where it was 4.59 and 4.70 t/ha, which exceeds the control variant by 0.7 and 0.8 t/ha. With the use of “Nutrivant Plyus”, the net income was 25.43 rubles/ha, the profitability level was 74.2 %. For the winter wheat variety Bagrat, the highest yield was also noted in the variant using “Nutrivant Plyus” – 4.70 t/ha, with a profitability level of 78.4 %.
