Abstract

Pakcoy plants are leafy vegetables widely cultivated with Urban Farming technology because they have high economic value. One of the technologies is the DFT (Deep Flow Technique) hydroponic method, and floating rafts are popular and widely used. This study aimed to determine the differences between the DFT and floating raft hydroponic methods on the growth and yield of 2 varieties of pakcoy plants. The study was conducted in January May 2024 at the Batu Urban Farming Green House. The design used was a Split Plot Design where the main plot of the hydroponic method (M) consisted of 2 levels: m1 = DFT and m2 = floating raft. The sub-plots were pakcoy varieties (V) consisting of (v1 = green pakcoy and v2 = red pakcoy). The results showed that the combination of the green pakcoy floating raft method treatment had the highest value in the number of leaves, leaf area, root length, root volume, total fresh weight, fresh weight for consumption, total dry weight, and dry weight for consumption.
