4.5 Prediction of Number of Fruits/Plot

 In the grove where the citrus yield mapping system was tested, two trees in each

plot were designated for hand-harvesting. Those trees were hand-harvested on

Feb. 6, 2004 and number of fruits per plot (NA), average weight of fruit in a plot (AvgWt),

minimum diameter of fruit in a plot (MinD), maximum diameter of fruit in a plot

(MaxD), average diameter of fruit in a plot (AvgD), average boxes per tree per plot

(AvgBT) and number of boxes per plot (NBP) were recorded, Table 4-7. This information

was used to develop yield prediction models.
