MODELLING A KIWIFRUIT ORCHARD |
| Authors: | R. Testolin, G. Costa |
| Abstract:
A computer model capable of predicting yield and fruit size distribution for kiwifruit orchards is described. The model is based on three rate variables, namely the proportion of fruit-bearing buds, the number of fruits per shoot, and the fruit weight distribution, which modulate the effect of a number of state variables related to orchard design (plant spacing, male to female ratio) and pruning strategy (cane density, length, and orientation), which are allowed to vary over a wide range of values. Differences in the effectiveness of wind, bee, and hand pollination in determining fruit size are also considered. Finally, the differential pricing of the fruit according to size provides information on grower returns. | |
