ABSTRACT
Horticultural crops are classified as annual and perennial crops. The planting system remains stable over years, while morphological adaptation of canopy and root develops according to the environment. Temporal data over more than one season are important, since historical plant data potentially provide valuable information on the status of endogenous growth factors, e.g., the status of phytohormones and assimilates. Horticultural products are the consequence of many manual operations and hand harvesting. In perennial fruit trees, several additional production measures like thinning of flowers and fruits, pruning are followed from time to time during the cropping period. Yield monitoring equipment was introduced in the early 90s and is considered as a conventional practice for modern agriculture. In Precision Farming (PA) as well as in precision horticulture, spatial information of the yield is pre-requisite for analysis and evaluation.
