This research aimed to study the most productive F1 hybrids of kale cabbage (Brassica oleracea var. Sabellica) through various cultivation methods under field and greenhouse conditions for the possible development of a green conveyor for year-round provision with fresh vitamins. Six selected hybrids of kale cabbage from the field during 2020–2021 sustained evaluation in the greenhouse using the nutrient film technique (NFT) technology and aquaponics. The recording of data included the growth and phenological parameters and yield. The three kale cabbage F1 hybrids stood out for productivity and quality indicators under field and greenhouse conditions. The kale F1 hybrids Dwarf Green Curled, Scarlet, and Nero di Toscana emerged with the highest yield indicators under field conditions. The hybrids Nero di Toscana, Scarlet, and Dwarf Green Curled had maximum yield increases of 195.3%, 461.58%, and 198.1%, respectively, with NFT technology compared with aquaponics. Overall, the kale F1 hybrid Dwarf Green Curled was remarkable, with the best results on productivity in long-term cultivation (from 1.5 to two months) under field and greenhouse conditions.
kale cabbage (Brassica oleracea var. Sabellica), hybrids, growth and phenological traits, productivity, hydroponics, aquaponics
The kale cabbage (Brassica oleracea var. Sabellica) hybrids showed better results both under field and greenhouse conditions. The three kale F1 hybrids, viz., Dwarf Green Curled, Scarlet, and Nero di Toscana, emerged as highly recommended for cultivation under field and greenhouse conditions using the NFT technology.
