First Year Survey Results Now Available

A sample of 271 Tango, W. Murcott Afourer, and White Murcott Mandarin varieties were randomly selected proportional to county and variety bearing acreage. Initial results show an average fruit set of 945 fruit per tree and an average fruit size of 1.49 inches in diameter for these varieties. Because this is a new survey, a production forecast will be not be made for at least three years.

Fruit counts were made from two trees per orchard, and fruit diameter measurements were taken on the right quadrant of four trees surrounding the two sampled trees.
