The production of Sathugudi oranges in South India is at present concentrated in parts of Cuddapah, Chittoor and North Arcot Districts. But nowhere has it attained such a great commercial importance as in Rajampet taluk of Cuddapah District, particularly in and around Kodur town. It has been estimated that out of a total area of about 13,000 acres under tight jacket orange, about 4,000 acres are spread out in a small valley in Rajampet taluk bounded by the Velikonda hills on the East and South and Sashachalam hills on the North and West. This tract is favoured by a fertile soil of considerable depth and good texture, a plentiful supply of sub-soil water suitable for irrigation, freedom from cyclonic winds and proximity to markets, factors eminently suitable for making this valley so renowned as the leading orange belt of South India.
