WebWe investigated five seed densities ranging from 7 to 21 seeds per square inch, which correlated to seed weights of 2.5 to 7.4 g/tray for arugula; 2.9 to 8.6 g/tray for mizuna; and 2.8 to 8.4 g/tray for mustard. For all three cultivars, harvested fresh weight (FW) increased as seed density increased from seven to 21 seeds/ tray (Figure 2).
