1. A method of forming a trellis support system, comprising forming a vertical post, the vertical post comprising: a post front portion; the post front portion comprising a post front aperture; the post front aperture comprising a first aperture portion and a second aperture portion adjacent the first aperture portion;a first post side wall adjacent to the post front portion;a second post side wall opposing the first post side wall;a first post rear portion extending from the first post side wall,a second post rear portion extending from the second post side wall; a number of post rear portions extending from the first and second post side walls, the post rear portions defining a number of rear portion apertures; andforming a cross arm, the cross arm comprising: a cross arm front portion;a first cross arm side wall adjacent to the cross arm front portion;a second cross arm side wall opposing the first cross arm side wall, and a number of cross arm rear portions extending from the first and second cross arm side walls, the cross arm rear portions comprising a number of cross arm tab members dimensioned to engage the rear portion apertures;dimensioning the cross arm front portion, first cross arm side wall, and second cross arm side wall to create an interference fit with respect to the post front portion, first post side wall, and second post sidewall, respectively. 2. The method of claim 1, further comprising: defining a post front aperture in the post front portion of the vertical post, the post front aperture comprising a first portion and a second portion adjacent the first portion;forming a first tab member on the cross arm front portion, in which the first tab member is dimensioned to engage the first portion of the post front aperture of the vertical post, andforming a lock member adjacent the first tab member, in which the lock member is dimensioned to engage the second portion of the post front aperture of the vertical post. 3. The method of claim 2, further comprising: forming a first cross arm rear portion extending from the first cross arm side wall;forming a second cross arm rear portion extending from the second cross arm side wall;defining a second aperture in the first post rear portion,defining a third aperture in the second post rear portion,forming a second tab member on the first cross arm rear portion, in which the second tab member is dimensioned to engage the second aperture on the first rear pc ion of the vertical post, andforming a third tab member on the second cross arm rear portion, in which the third tab member is dimensioned to engage the third aperture on the second rear portion of the vertical post. 4. The method of claim 3, further comprising punching, stamping, cutting, or combinations thereof the first aperture, second aperture, and third aperture. 5. The method of claim 3, further comprising punching, stamping, cutting, or combinations thereof the first tab member, lock member, second tab member, and third tab member. 6. The method of claim 3, further comprising: forming a first tip portion on the second tab member of the first cross arm rear portion, in which the first tip portion is dimensioned to engage a surface of the first post rear portion; andforming a second tip portion on the third tab member of the second cross arm rear portion, in which the second tip portion is dimensioned to engage a surface of the second post rear portion. 7. The method of claim 2, further comprising: defining a number of post front apertures in the vertical post;forming a first tab member and lock member pair in a number of cross arms,in which the vertical post accommodates a number of cross arms along the length of the vertical post. 8. The method of claim 2, further comprising forming the vertical post and cross arm from steel, metal, metal alloys, plastics, polymers, fiberglass, carbon fiber reinforced plastics, resins, or combinations thereof. 9. The method of claim 2, further comprising forming a standoff distance between the underside of the first tab member and the cross arm front portion. 10. The method of claim 9, further comprising creating an interference fit between the first tab member and the post front portion by having the standoff distance be approximately equal to the thickness of the post front portion. 11. The method of claim 9, further comprising forming the standoff distance less than the thickness of the post front portion to create an interference fit between the first tab member and the post front portion. 12. The method of claim 2, further comprising forming the first tab member and the lock member to he dimensioned with respect to the post front aperture of the vertical post to create an interference fit between the first tab member and the lock member, and a first aperture portion and a second aperture portion of the post front aperture. 13. The method of claim 2, further comprising forming an upending tip portion on the lock member to abut against the second aperture portion of the post front aperture in opposition to the first tab member. 14. The method of claim 1, further comprising roll-forming the vertical post. 15. The method of claim 1, further comprising forming a number of returns on the vertical post to strengthen the vertical post and prevent premature failure of harvester beater bars. 16. The method of claim 1, further comprising forming a number of comings on the post front portion, the first post side wall, and the second post side wall of the vertical post to create an interference fit between the cross arm front portion, first cross arm side wall, and second cross arm side wall of the cross arm and the post front portion, the first post side wall, and the second post side wall of the vertical post. 17. The method of claim 1, further comprising forming a number of wire slots in the cross arm to carry a number of trellis wires. 18. The method of claim 17, further comprising: forming a first carrying portion in each of the wire slots;forming a second carrying portion in each of the wire slots; andforming a flanged opening, the flanged opening comprising an upturned flange portion to create an opening for insertion of the trellis wires into the wire slots, while preventing the trellis wires from sliding out of the wire slots.
