kolza

Kolza refers to the common name for plants in the genus Brassica, particularly those cultivated for their oil-rich seeds. While often used interchangeably with canola, the term "kolza" can also encompass other related species like Brassica rapa. The most common type of kolza grown commercially is Brassica napus, from which canola oil is derived.

The cultivation of kolza has a long history, with evidence suggesting its use in agriculture dating back centuries. Its popularity stems from the versatility of its seeds, which are processed to produce vegetable oil for human consumption, animal feed, and industrial lubricants. The residual meal after oil extraction is also a valuable source of protein for livestock.

Kolza plants are typically annuals or biennials with yellow flowers. They are grown in temperate regions worldwide, with major production areas including Canada, Europe, China, and Australia. The crop requires specific growing conditions and can be susceptible to pests and diseases, necessitating careful agricultural management.

In recent decades, the development of low-erucic acid, low-glucosinolate varieties of Brassica napus has led to the widespread adoption of canola oil. This refinement made the oil more suitable for a wider range of culinary uses and dietary guidelines. The term "kolza" itself is of Slavic origin and has been used to describe oilseed rape for centuries.
