This research aimed to determine the effect of N fertilizer dose, number of plant/hole, and their interaction on the growth and yield of shallots. The research used a Randomized Complete Block Design (RCBD) with two factors: various doses of N fertilizer (P) (P1=90, P2=180, and P3=270 N kg/ha) and number of plant/hole (T) (T1=1, T2=2, T3=3, and T4=4). The observed variables were plant height, number of leaves, leaf area, chlorophyll content, stomata opening width, stomata density, weight of fresh and dry leaf, root and tuber, fresh and askip tuber yield, root length, number of roots, number of tubers, and tuber diameter. Obtained data were analyzed using F test then followed by Duncan Multiple Range Test (DMRT) of 5% level if diversity occur. The results showed that N fertilizer of 180 kg/ha produced higher plant height (25.78 cm), density of morning and evening stomata (71.86/mm 2 67.03/mm 2 , respectively) with fresh tubers yield of 8.48 t/ha. One plant/hole showed higher yield of tuber diameter (4.68 cm), two plants/hole showed higher height (25.67 cm), and four plants/hole showed higher number of leaves (9.38 strands), roots (73.56 strands), and tubers (4 pieces). There was no interaction between both factors to the observed variables.
