Abstract

Kale (Brassica oleracea var. Achepala) is a leaf vegetable plants from the Brassica family that has high potential to develop. The use of nutrients in hydroponic cultivation has important role to fulfil the nutrient needs of curly kale plants. The presence of nitrogen is important for kale in growth and crop result. Cultivation with floating raft system needs to focus into the ideal population to get an optimal growth rate. This study aimed to obtain the correct amount of nitrogen concentration and plant population on the growth and yield of curly kale with floating raft hydroponic system. This research conducted in the Green house experimental field of Agriculture Faculty, University of Brawijaya on August 2022 to November 2022. The research using Factorial Randomized Block Design with 2 factors and 3 replication. The first factor is nitrogen concentration of hydroponic nutrients, and the second factor is plant population. The result implies that Nitrogen concentration 2M with 4 plants population given higher EC value. 1,5M nitrogen concentration on 4 population plants and 2M nitrogen concentration on 6 plants population given the higher leaf area. Combination of nitrogen concentration of 1M and 2M and 8 plant population gives higher fresh total weight per container. 2 M nitrogen concentration given higher number of leaves and EC value in the media, but given shorter result the root length of curly kale than nitrogen concentration of 0,5M. 8 plants population gives lower number of leaves and root length than 4 curly kale plants population.
