Đánh giá sinh trưởng và năng suất bốn giống cải kale (Brassica oleracea var. sabellica) trồng bằng phương pháp thủy canh tĩnh

Abstract

This research was conducted at Can Tho University to evaluate the growth and yield of 4 varieties of kale grown by the non-circulating hydroponic method under greenhouse conditions. The experiment was arranged in a completely randomized design, consisting of 4 treatments and 10 replications. The four treatments were 4 varieties of kale, including Xoan xanh kale, Rong bien xanh kale, Xoan tim kale, and Thuy tinh kale. The treatments were arranged in greenhouse conditions, and styrofoam boxes were used to grow kale hydroponically. The results showed that there were differences in growth and yield of 4 varieties of kale. In which, Xoan xanh kale variety had leaf length (28.4 cm), stem diameter (10.2 mm), average leaf weight (13.9 g/leaf), total leaf weight obtained per plant (324 g/plant), and vitamin C content in leaves (37.4 mg/100 g) were the highest among the four kale varieties in the experiment. Rong bien xanh varieties have the highest number of leaves per plant (33.5 leaves/plant), but the leaf length (18.8 cm) and vitamin C content (15.5 mg/100 g) are the lowest. The Xoan tim variety has the largest leaf width (12.8 cm), but the lowest number of leaves per plant (21.5 leaves/plant) and the lowest total leaf weight harvested per plant (101 g/plant).
