Abstract:
Caisim (Brassica chinensis chinensis The Var) are the vegetables that
contain vitamins and minerals. Needs caisim Pekanbaru in Riau particularly
increased, along with the increase in population. For the consumer society and
knowledge of vegetables with high incomes, tend to selectively choose
vegetables that are hygienically protected from chemical residues. The use of
organic fertilizer or compost can produce organic vegetables is more hygienic,
safe for the consumer and environmentally friendly. Compost can be made from
plants that are less beneficial, one water hyacinth. The purpose of this study, to
determine the effect of the use of organic fertilizers with various bioactivator
hyacinth, on the growth and production caisim. The research was carried out
experimentally by using a Completely Randomized Design (CRD) factorial,
comprising: first factor fhe use of compost (K) with various bioactivator namely
K0: hyacinth compost without microbes, K1: Compost of water hyacinth with
microbial degradation Simba. K2: Compost of water hyacinth with microbial EM-
4. The second factor is the provision of inorganic fertilizer (A) consisfs of three
levels: A0: Without inorganic fertilizers, A1:1/2 the recommended dosage which,
urea, 37.5 kg / ha, SP-36 37.5 kg / ha and 25kg KCI / ha , A2: the recommended
dosage, Urea 75 kg / ha, SP-36 75 kg / ha and 50 kg KCI / ha. The results showed
that treatment K2A1 with water hyacinth compost activator Bioaktivator EM4 with
1/2 recommended doses of inorganic fertilizer showed the highest production
with a weight of 298 grams of fresh plants / plot.
