ABSTRACT

The article presents scientifically grounded approaches to feed production in the context of risky agriculture in the Republic of Sakha (Yakutia), with a focus on the impact of climatic factors such as extreme temperature fluctuations and a short growing season on traditional agricultural methods. This highlights the necessity of implementing modern technologies, including precision farming and genetically modified crops. In 2024, a total area of 50.9 hectares was sown with sorghum-sudan grass hybrids, oats, and mixed crops. The climatic conditions were characterized as severely drought-prone, with an average daily temperature of +9.1 °C in May and +19.3 °C in June, while precipitation in May was only 7.3 mm. According to the results, the sorghum-sudan grass hybrid reached a height of 120 cm with a yield of 17.4 tons/ha; oats reached 70 cm with a yield of 10.0 tons/ha; vetch yielded 12.3 tons/ha; and peas yielded 14.0 tons/ha. The application of the biological preservative Bonsilage contributed to a reduction in nutrient losses, resulting in the harvesting of 530 tons of silage with quality parameters including a protein content of 30.37%, crude fiber of 24.05%, and a pH of 4.5. The implementation of these technologies increased milk yield from 2800 to 3787 liters per cow per year (a 35% increase). Thus, the results confirm the effectiveness of scientifically grounded methods of feed production and the use of modern technologies, which improve the quality of forages and enhance livestock productivity under the conditions of risky agriculture in the Republic of Sakha.
