Reader's Guide
The Bangalore rose onion is significant as a unique agricultural product of Karnataka, distinguished by its deep scarlet red color, high pungency, and nutritional content including higher levels of protein, phosphorus, iron, and carotene. Its exclusive cultivation in the Bangalore region, due to specific soil and climate requirements, underscores its regional identity. The Geographical Indication tag awarded in 2015 protects this identity and grants patent rights to the Bangalore Rose Onion Growers' Association. Economically, the onion is rarely consumed in India but is exported in large quantities to countries such as Malaysia, Singapore, Indonesia, Bahrain, UAE, Bangladesh, and Sri Lanka. In the financial year 2010–11, over 22,000 tonnes were exported, though this was lower than the 36,000 and 32,000 tonnes exported in 2003–04 and 2005–06 respectively. After an Agri Export Zone was set up for the crop in Karnataka, more than ₹500 crore worth of rose onion was exported in five years.
