Birba is a bulb onion (Allium cepa L.) hybrid registered in official breeding achievement registries. Open publications lack data on its biological properties, such as plant height, maturity dates, and disease resistance.
When searching for information, it is important to consider the existence of a tomato hybrid of the same name and other non-agricultural brands named Birba, as data on them is often conflated in search engines.
