a Farm size is defined by the range of acres in each category. For example, acreage of Small farms ranged from 1 to 5.9 acres and for the four Large growers the farm acreage ranged from 86 to 305 acres.
b Historical acres refers to the total papaya acreage in the Puna region just prior to the first observation of papaya ringspot virus infection on papaya. Thus, historical data was reported for different years, from 1992 when papaya ringspot virus first entered the Puna area, to 1997 at which time all farmers in this survey had observed infected plants in their fields.
c Percent of acreage by farm size.
