Prediction of apple quality distribution at harvest

To improve the logistics of filling storage rooms with fruit of homogeneous quality at harvest, there is an obvious need for early information related to fruit quality. Using a modelling approach prediction of fruit quality distribution at harvest has been studied. The presented model is based on the state-space model. Predicted data consistently describe well the observed packing-houses measurements for 3 different apple varieties for 2 years. The application possibilities of the presented approach are discussed.
