Abstract: There is interest among small vegetable producers to grow collards in Tunnel Houses during the winter months. Consequently, the purpose of this study was to determine if collard yields could be increased by reducing row spacing and increasing plant density. This study had four treatments replicated three times, and “Georgia” and “Hi-Crop Hybrid” collards were transplanted on single, and staggered rows spaced 18” and 24” apart in a split-split-plot design. At 45 days after transplanting 50% of the leaves from all plants in each treatment were harvested, counted, and weighed. The results showed staggered 18 and 24” rows increased yields by 43 and 51%, respectively, over single planted rows for both varieties. Staggered rows incurred higher planting costs, but increased net returns to management. The increase in yield was variety-dependent, thus suggesting that the genetic potential of the varieties needs to be considered when using plant density to increase yields.
