Rice plants (Oryza sativa) are a significant food crop. Tobacco plants (Nicotiana tabacum) can be beneficial and affect growth due to allelochemical content. The srudy aims to determine the effect of tobacco extract (N. tabacum) on the growth and yield of rice (O. sativa) Inpari-32 variety. The study method used the RBD as an experimental design. Three treatments with different concentrations of tobacco extract and one control with three replications. Growth variables were observed: growth rate, plant height, number of tillers, number of leaves, shoot and root dry weight, flowering age, and phytohormones. Observations of the harvest stage include the weight of stover, number of panicle seeds, the total number of tillers, weight of 1000 seeds, the ratio of the weight of filled grain, and productivity (tons/ha). The results showed that although not significant, tobacco extract treatment increased the number of tillers and leaves, the content of phytohormon IAA in the vegetative phase, the content of GA3 in the generative phase, shoot-root ratio, number of tillers, and accelerated flowering age. The implication of tobacco extract positively affects the plant growth variable and accelerated flowering age of rice variety (O. sativa) Inpari 32.
