Abstract

Oranges have been cultivated in nearly all parts of the world where rainfall or irrigation can support their growth, resulting in high levels of fruit production. Global orange production is estimated at around 60 million tons per year. Major orange-producing countries include Australia, Brazil, China, Cuba, Egypt, India, Israel, Italy, Japan, Mexico, Morocco, South Africa, Spain, and the United States (Whiteside, 1989).

Indonesia’s natural potential strongly supports the development of tropical fruits as leading commodities. Variations in climate, land conditions, and altitude across regions allow for differences in harvesting times, ensuring year-round fruit availability. In addition, the potential land area for fruit crop development remains substantial. According to data from the Central Bureau of Statistics, there are 4.9 million hectares of yard land, 12.8 million hectares of dry land, and approximately 9.7 million hectares of uncultivated land (Soerojo, 1992).
