Aira is classified within the genus of beardless brome (Bromus inermis Leyss.). This plant is characterized by the presence of remnants in the glumes, which is reflected in its name derived from the ancient root *kes-/kos-, meaning 'to cut, to slice'. In Russian, a similar word is 'koster', and in other Slavic languages, variants include: Polish kostrzewa, Bulgarian koshtrava, and Slovenian kostrȇvec.
Botanically, Aira is an annual plant with thin leaves and spikelet inflorescences. Due to its structure, it is frequently used in agriculture as a fodder crop for livestock. Additionally, it can be applied as mulch or ground cover, as it can quickly cover the soil, retain moisture, and suppress weed growth.
The advantages of Aira include drought resistance and the ability to adapt to various soil types. This makes it a valuable resource for farmers seeking to increase pasture productivity and improve fodder quality. Due to its ease of cultivation and low maintenance requirements, Aira is becoming a popular choice among agricultural enterprises looking for reliable and cost-effective solutions for animal feeding.
