The research was conducted using a factorial Randomized Complete Block Design (RCBD) consisting of two factors. The first factor was urea fertilizer treatment with three levels: U0 = control, U1 = 3 g/polybag, and U2 = 6 g/polybag. The second factor was the dose of goat manure (K) with three levels: K1 = control, K2 = 200 g/polybag, and K3 = 400 g/polybag. The interaction between urea and goat manure doses had a significant effect on plant height, stem diameter, number of leaves, leaf length, leaf width, and leaf area.}, issn = {2654-3915}, pages = {44--56}, doi = {10.46930/ojsuda.v33i2.5680}, url = {https://jurnal.darmaagung.ac.id/index.php/jurnaluda/article/view/5680} }
