Florida will rebound from a poor citrus crop last year with a 30 percent increase in orange production this year, the federal government predicted Friday.The United States Department of Agriculture orange forecast for Florida is 168 million boxes, each of which weighs 90 pounds. Last year, the state hauled just 129 million boxes, its worst season since devastating freezes in the 1980s. Florida is by far the nation's leading citrus producer, but crop diseases, hurricanes and drought have crippled production the past few years. The state routinely produced more than 200 million boxes from 1999 until 2004.
