Abstract: Vertical trellising agriculture is used in indoor and outdoor applications. Drawbacks of vertical trellising are known in the art, and usually concerns aspects related difficulties in compactization of the modules and cascading the production, especially in indoor controlled environments, where typical yields are up to about 350 Kg/m2 floor. The present invention discloses multi-story horizontal trellising systems and modules thereof; and provides a modular vertically stackable trellising means with greater yields per square meter floor.

Abstract: The present invention provides a plant grafting method using a plurality of rootstocks grafted together to one scion. A collar is positioned around at least one rootstock to limit a period of its contribution for growth and development of said plant. The grafting method benefits from simultaneous utilization of plurality of rootstocks with versatile growth control.

Abstract: A method for suggesting associations between at least two subscriber/users or WWW surfers, in which compatibility between users is calculated based upon at least compatibility of subscriber/users. Such a compatibility is calculated based upon at least one compatibility parameter. One notable parameter is a satisfaction level (SL) parameter. The SL parameter is derived in a typical case from the dwell time of the subscriber/users, associated with specific web objects.
