<![CDATA[The purpose of this research was to assess the effect of several type of growing media and AB Mix substitution with organic nutrition to Kailan (Brassica oleraceae L.) growth. The study was conducted using a factorial 3 x 4 completely randomized design (CRD) with 3 replications. First factor is the treatment of growing media which consists of Rockwool, Charcoal husk, and Cocopeat. The second is the AB Mix Substitution with organic nutrition consisting of AB Mix substitution with 0% organic nutrition, AB Mix Substitution with 25% organic nutrition, AB Mix Substitution with 50% organic nutrition, and AB Mix Substitution with 100% organic nutrition. Growth parameters observed included plant height, number of leaves, root length, canopy wet weight, root wet weight, canopy dry weight, root dry weight, and chlorophyll. Data were analyzed using ANOVA and continued by DMRT (Duncan's Multiple Range Test) at 5% level. The results showed that the planting media treatment was able to increase growth in the plant height, number of leaves, root length, canopy wet weight, root wet weight, and canopy dry weight. The treatment of AB Mix substitution with 25% organic nutrition is equivalent to the treatment of AB mix substitution with 0% organic nutrition for all parameters except chlorophyll. The AB Mix substitution treatment with 50% organic nutrition is not equivalent to the treatment without substitution. The higher substitution treatment will affect growth.]]>
