data collected in the field (fruit size) using Calibit, the digital caliper with datalogger onboard. Proprietary algorithms were created for the main varieties of apple and pear. Perfrutto provides forecasting information allowing growers to optimize irrigation, fruit thinning and fertilization. Their goal is the success of the growers making them able to produce the best possible fruit quantity and sizes. PerFrutto maximizes crop yield (+20% = +4K€/ha) and optimizes the production. Fruit can be used as natural active drivers for irrigation management. Early information about production (size and quantity) is fundamental for commercial staff.
