The invention, from a first aspect, provides an assembly of several reels (2) with guide wires (3) for crops, wherein the guide wires (3) have partially been wound around the reels (2) and partially extend away from the reels (2) with a free end portion (3a), wherein of at least a number of the reels (2) the free end portions (3a) of the guide wires (3) have been joined together with joining means (8). Due to the joining together in a group using the joining means, the guide wires (3) can be situated in an orderly manner in, on or near a storage container for the assembly. Due to the joining together the guide wires (3) can moreover remain unidirectionally oriented one to the other, as a result of which the guide wires (3) getting tangled when taking a reel (2) out of the assembly can be counteracted.
