Where cocoa plants occupy the third largest position in meeting the country's foreign exchange in the plantation sub-sector so that it is necessary to increase the growth of cocoa plants by increasing nutrients. One of the ways to increase cocoa plant nutrients is by providing fermented goat urine liquid organic fertilizer. This study aims to determine the effect of fermented goat urine on the generative growth of cocoa (Theobroma cacao L). The hypothesis of this study is that giving goat urine with various concentrations will have an effect on the growth of cacao seeds (Theobroma cacao L) in polybags. The research method used was an experimental method using a completely randomized design (CRD) pattern with 5 treatments and 3 replications, namely the concentration of control K0 / ordinary water, K1 100 ml / l, K2 200 ml / l, K3 250 ml / l, K4 300 ml / l. The observation parameters were plant height (cm), plant dry weight (cm), crown dry weight (cm), and plant crown ratio. Data were analyzed by one-way analysis of variance (ANOVA), followed by Duncan's test (DNMRT) to determine the differences between concentration factors. The results of the analysis carried out in the laboratory showed levels of N 1.35%, K 2.10%, P 0.13, and 0.16% organic C.
