Pakcoy (Brassica rapa L.) is an economically valuable horticultural crop whose growth can be improved with organic fertilizers. This study examined the effects of cow manure and liquid organic fertilizer from rabbit urine on pakcoy growth and yield. The research was using a factorial randomized block design. Cow manure was applied at 0, 1, 2, and 3 kg per plot, while rabbit urine fertilizer was applied at 40, 50, and 60 ml per plot. Observed variables were plant height, leaf number, and plant weight per plot. Results showed that cow manure significantly affected all variables. The 2 kg per plot treatment gave the best results, while rabbit urine fertilizer and interaction effects were not significant
