Mustard is one of the horticultural commodities that have commercial value and is favored by the people of Indonesia. And one of the efforts to increase the yield of mustard plants is to perform optimal cultivation techniques, including fertilization. The purpose of the study was to determine the dose of urea fertilizer with liquid complementary fertilizer on the growth and yield of mustard greens. The study was conducted in Moncongbalang Village, Barombong District, Gowa Regency, South Sulawesi, in February-April 2019. The study used a Randomized Block Design (RBD) consisting of 8 treatments with 4 replications. The arrangement of treatments was as follows: P1= Urea 200 kg-1; P2= manure 20 t ha-1+ Urea 200 kg ha-1; P3= Urea 200 kg ha-1+10 cc LFC; P4= Urea 150 kg ha-1+10 cc LFC; P5= Urea 100 kg ha-1+10 cc LFC, P6= Urea 200 kg ha-1+15 cc LFC; P7= Urea 150 kg ha-1+15 cc LFC, and P8=Urea 100 kg ha-1+15 cc LFC. Parameters observed were plant height, number of leaves, leaf area, fresh weight of shoots and roots, fresh weight of plants, and yield of mustard greens and economic analysis. The results showed that the combination of Urea fertilizer 150 kg ha-1+15 cc PPC gave the highest yield compared to other treatments, namely 5.8 t ha-1with an R/C ratio of 2.17.
