N2 - The domestic consumption of rice (Oryza sativa) in Indonesia are increasing because of the population growth. One of the ways to increase rice productivity is by using external compounds such as plant growth regulators (PGRs) or phytohormones that function to affect growth. Tobacco plants can also be used as PGR because they contain allelopathic substances, organic matter, and other phenolic compounds that can affect plant growth. This study aims to determine the effect of intervals of tobacco extract application on the growth and yield of rice plants of the Inpari 32 variety. The study was conducted in a Randomized Block Design (RBD) with 4 interval treatments (control F0; once a week F1, once every two weeks F2, and every three weeks F3). One-Way ANOVA test was done at a 5% level and continued with a DMRT test, with variables of plant height, number of leaves, number of tillers, growth rate, phytohormones (auxin IAA; and gibberellic acid GA3), flowering age, harvest age, shoot and root dry weight, stover shoot root ratio, 1000 grain weight, the ratio of pithy rice grain to rice grain. Total, seed weight per clump, grain weight per plant, and productivity (tons/ha). The study results were that the application interval treatment did not show a significant effect on all test parameters, but the treatment interval of application of tobacco extract once a week (F1) showed a tendency for better results especially in the number of leaves.
