The winter barley variety Carioca is a medium-early and productive type, intended for green feed production. Studies conducted in the Republic of Adygea on heavy clay black earth soils showed that this variety demonstrates stable yield under proper agronomic practices. The most effective cultivation method is plowing with application of 60 kg of nitrogen per hectare, which ensures a yield of up to 7.4 tons of green mass per hectare. Regarding nutrient content, Carioca belongs to the low- and medium-protein feed category, but in terms of energy value and feed units, it corresponds to first-class feed, making it a valuable component in animal feeding.
To increase yield and quality of feed, it is recommended to use potassium humate, which, when applied to seeds and crops at various growth stages, increases yield by 13.7% and improves the nutritional characteristics of the plant. This indicates the high adaptability of the variety to plant growth regulators and the potential for increased productivity through modern agronomic technologies.
Thus, winter barley Carioca is a promising variety for producing green feed with good energy value. Its cultivation requires adherence to optimal agronomic practices, including proper soil preparation and fertilizer application, as well as the use of plant growth regulators to maximize yield and improve the quality of the feed base.
