Pengaruh Ketinggian AB Mix Terhadap Pertumbuhan Caisim Menggunakan Modifikasi Hidroponik Sistem Wick

The Effect of AB Mix Height on the Growth of Caisim Using the Modified Hydroponic Wick System

Abstract

An important factor in cultivating plants using the hydroponic system is providing AB mix nutrients with the appropriate concentration and solution discharge. Supplying and controlling the nutrient level can use a modified wick system tool designed based on several levels of nutrient height. This research aims to determine the effect of AB mix nutritional levels on choy sum growth. The study was carried out from August to September 2023 in the BSIP’s greenhouse of the Ministry of Agriculture, Cimanggu, Bogor. The design used was a completely randomized design (CRD) with one factor, namely the level of AB Mix nutrient solution in 3 height levels: 2 cm (N1), 3 cm (N2), and 4 cm (N3), and used six replications. The ANOVA test showed no effect of nutrient level on plant height, leaf number, and leaf width at all ages of observation. However, nutrient height had a significant effect on the root length of choy sum plants, which in treatment N1 (18.26 cm) had the highest average root length compared to treatments N2 (14.54 cm) and N3 (13.77 cm). The findings explain that the lower the AB mix height, the longer the choy sum roots.
