The experimental material consisted of three kale cultivars: Winterbor F1, Redbor F1 and Medium High Green Curly were obtained from three harvest dates. The experiment was conducted in a three-year cycle (2006-2008). Total yields ranged from 5.13 to 9.32 kg·m-2, of which marketable yield constituted on average 51-72% and processing yield 27-34%. In the present experiment, 8.42 kg of total yield per 1m2 was obtained from Winterbor F1, 7.55 kg from Medium High Green Curly cv. and 6.71kg from Redbor F1 as an average for all years and harvest dates. The highest total yield for all cultivars was from the second harvest date and ranged from 6.76 to 9.32 kg·m-2. The dry matter yield of leaves with removed veins averaged between 0.28 and 0.50 kg per 1m2 for all years and harvest dates.
