Plug seedlings of Celosia cristata L. `Persimmon Chief' were planted in four production systems (harvest lugs, lay-flat bags, pots, and polystyrene trays) on 7 May 2004. Production systems were randomized in a Latin-square design with four replications of each system. Each treatment plot was 0.7 m × 1.1 m. Planting density was 31 plants/m2. The harvest lugs were 55 cm × 37 cm × 16 cm. The lay-flat bags were 114 cm × 30 cm × 3 cm. The pots were 25 cm bulb pans. The polystyrene trays were 67 cm × 34 cm × 5 cm and contained 32 square cells. All of the containers were filled with the same tobacco germination media. The plants in the harvest lugs, lay-flat bags and pots were irrigated daily with 150 mg·g-1 N from 20N–4.4P–16.6K. The plants in the polystyrene trays were floated on a solution of 150 mg·g-1 N from 20N–4.4P–16.6K. Float solutions were monitored and adjusted weekly for volume and fertilizer concentration. Individual stems were harvested at the appropriate stage of development for market. The fresh weight, stem length and flower diameter of individual stems were recorded. Stems produced in float trays had the lowest fresh weight (162.2 g). Stems grown in harvest lugs (363.5 g) weighed more than those in pots (298.4 g) but not lay-flat bags (338.4 g, lsd 0.05 = 42.7). Stems grown in float trays (88.8 g) were shorter than lay-flat bags (121.5 g), harvest lugs (120.5 g), and pots (113.5 cm, lsd 0.05 = 10.5). Flower diameter did not differ between production systems (mean diameter = 7.2 cm).
