Plots with short rows provide an attractive alternative to hill plantings where seed or space is scarce. The lower planting density in short rows allows for more normal phenotypic expression and easier separation of individual plants. This paper describes an attachment for the Swift Current self-propelled plot seeder for sowing 0.5 m rows perpendicular to the direction of travel. The attachment consists of a spade-type opener supported by a linkage which allows it to move in a vertical plane, a seed distribution systcm, and a control system. Hydraulic cylinders automatically move the opener up and down and open and close the opener blades. In the down position, a 0.5 m long furrow is opened and seeds are dropped into the furrow; in the up position, the opener advances to the next row. The automatic control system both controls and synchronizes the opener movements and the dropping of seeds to ground speed. Border rows can be sown at either end of the micro plots and parallel to the direction of travel with the outside two double disc openers on the seeder.
