Abstract
Kailan is one vegetable grown to suit market demand, especially in major cities with bright development prospects and middle-class and urban customers. Hydroponics, which uses water instead of soil to give nutrients and minerals, saves space and time and produces higher-quality plants.
This study investigated the effects of (1) variety, (2) planting medium, and (3) the interaction between varieties and growing media on the growth and yield of kailan plants in the DFT hydroponic system.
The research was place in Tani Jaya Anggara Farm^s greenhouse and gardens in Rajabasa, Bandar Lampung, from November 2018 to January 2019. The experiment was set up in a Completely Randomized Design (CRD). The first component, variety (V), had two levels: winsa (v1) and full white (v2). The second factor, planting medium (M), had four levels: rockwool (m1), foam (m2), cocofiber (m3), and cocochip (m4) (m4). each repeated three times, the experimental unit had 15 plants.
The results revealed that (1) Winsa variety generated greater kailan plant height and net assimilation rate than complete white variety in DFT hydroponic system, and (2) Cocochip growing material produced more leaves, relative growth rate, and wet weight. compared to rockwool, foam, and cocofiber planting medium in DFT hydroponic systems, (3) Except for net absorption rate, varietals and growing media did not interact. LAB of winsa variety is usually lower than complete white, except for cocochip media.
