The influence of biological preparations on the productivity and use of moisture by winter barley plants in the conditions of the Southern Steppe of Ukraine

In the Southern Steppe of Ukraine, the agricultural sector attaches primary importance to grain production. Wheat stands out as the dominant crop among the diverse cultivated plants of this region. In place of spring wheat, a significant part of crops is occupied by winter barley. The combination of winter and spring contributes to the growth of both crops, ensuring a diverse and high yield [1]. For the intensification of grain production and the full use of the biological potential of spring barley varieties, the development of resource-saving growing technologies is relevant in modern times. The steppe zone of Ukraine presents difficult conditions for agricultural crops, as rising temperatures and drought limit their productivity by depriving them of moisture. Among the decisive factors for successful plant growth, moisture plays a significant role, but when it comes to the technology of growing winter barley, one of the key elements that cannot be forgotten is nutrition, as it plays a significant role in the development of all agricultural crops
