An assembly for handling fruit and vegetable products includes first containment units for fruit and vegetable products that can move along a first conveyance and/or control line. The assembly further includes second containment units for horticultural products that can move along a second conveyance and/or control line, which is laterally adjacent and proximate to the first line. The assembly includes a plurality of elements for transferring the horticultural products; such elements are distributed at least along a part of the first line and are selectively actuatable by an electronic management and control unit, for the transfer of each product from a first unit to a respective second unit in a portion chosen from a plurality of different portions of the first line, upon the occurrence of a predefined condition of mutual alignment between the horticultural product to be transferred, which is conveyed by the first unit, and a second unit.
