Citrus fruits like lemon and oranges are primarily grown in the Brahmaputra Valley of Assam. The Brahmaputra Valley is a fertile plain located in the central part of Assam. It is the most densely populated region of Assam and is home to the state’s capital, Guwahati. The Brahmaputra Valley is well-suited for the cultivation of citrus fruits due to its warm climate and abundant rainfall. The region also has a long history of citrus cultivation, dating back to the 16th century.
