Phenological Treatments

Crop Forcing is a new technique based on moving the grape-ripening period from hot summer months to a cooler month later in the growing season. This is achieved by making an additional pruning (severe leaf removal), stopping the natural cycle of the plant and forcing the plant to restarting its cycle later.

One of the main obstacles is to decide when to apply the additional pruning. One goal of VISCA is to have enough accurate models to predict plant behavior after this sever summer pruning (based on accurate predictions of meteorological data), which will help to determine the appropriate moment to apply the additional pruning.

In order to develop these models, different field experiments are implemented, like the ones on the photos where it’s possible to observe three different Crop Forcing treatments. These treatments are necessary to analyze vine phenological evolution, and with this data to feed the models.
