Rice (Oryza sativa) is an important cereal, it represents the staple food of half of the world's population, it provides nutrients such as carbohydrates, lipids and proteins. The objective of study is to evaluate the treatment of rice seed with biologicals, determining its germination, vigor and phytosanitary. The treatments evaluated were eight using a seed inoculation with two biologicals based on Trichoderma harzianum (1x1012 CFU/g) at a rate of 0.661g/kg of seed and Bacillus subtilis (1.8 x1012 CFU/ml) more Pseudomonas fluorescens (1.4 x1012 CFU /ml) at 2.2 ml/kg of seed, these were: T1: Anar 2021, T2: Santa Rosa, T3: Lazarroz, T4: Irga 424, T5: Anar 2021 (without inoculant), T6: Santa Rosa (without inoculant), T7: Lazarroz (without inoculant) and T8: Irga 424 (without inoculant). The variables evaluated were germination, vigor, vigor index, foliar incidence of bacteria and seedling mortality. The study carried out demonstrated significant differences between treatments and interactions in germination, vigor, vigor index, foliar incidence of bacteria and seedling mortality. T1: Anar 2021 reached higher values of germination, vigor and vigor index; 93 %, 90 % and 2,056 % respectively; being lower values of foliar incidence of bacteria and mortality of seedlings with 4.2 % and 6.0 % respectively.
