Abstract

False pak choi (Brassica rapa var. chinensis) is a vegetable that can be grown for home consumption or for sale. Therefore, soil or planting materials should be selected that are suitable for the plant's growth. The objective of this study was to investigate growth of False pak choi on sunn hemp (Crotalaria juncea) soil-based. The experiment was conducted using false pak choi in a planting test by arranged in completely randomized design (CRD), 9 treatments and 4 replications. Nine treatments consisted of T1 : soil (control), T2 : coconut dust : rice husk : cow manure : chicken manure (1 : 1 : 1 : 1 : 0.5, v/v) , T3 : coconut dust : rice husk : cow manure : chicken manure : sun hemp , (1 : 1 : 1 : 1 : 0.5 : 1, v/v) , T4 : rice husk : cow manure : chicken manure : sun hemp, (1 : 1 : 1 : 0.5 : 1, v/v) , T5 : coconut dust : cow manure : chicken manure : sun hemp, (1 : 1 : 1 : 0.5 : 1, v/v) , T6 : coconut dust : rice husk : cow manure : sun hemp, (1 : 1 : 1 : 1 : 1, v/v), T7 : coconut dust : rice husk : chicken manure : sun hemp, (1 : 1 : 1 : 0.5 : 1, v/v), T8 : coconut dust : rice husk : sun hemp , (1 : 1 : 1 : 2,  v/v), T9 : cow manure : chicken manure : sun hemp , (1 : 1 : 1 : 2,  v/v). The experimental results showed that False pak choi had highest growth and yield when grown on T9 and T5.
