El estudio se desarrolló en el municipio Los Palacios, con el objetivo de evaluar el efecto de los bioestimulantes Biobras-16® y QuitoMax®, en el rendimiento y sus componentes de una línea avanzada de arroz y el cultivar comercial INCA LP-5, como estrategia para incrementar los rendimientos en estas condiciones edafoclimáticas. Se evaluaron los dos genotipos con los bioestimulantes de manera independiente y la combinación de ambos en dos etapas del cultivo, empleando dosis de 25 mg ha-1 de Biobras-16® y 50 mg ha-1 de QuitoMax®. Se utilizó un diseño completamente aleatorizado con arreglo bifactorial, con ocho tratamientos de tres réplicas cada uno y se evaluaron cinco caracteres cuantitativos. Los datos obtenidos se sometieron a un análisis estadístico univariado. El rendimiento agrícola fue superior cuando los genotipos se trataron, confirmando las potencialidades del Biobras-16® y el QuitoMax® para ser utilizados como estimuladores de este carácter en el cultivo del arroz. Los mejores resultados se logran con las combinaciones de Línea 1 con QuitoMax® y la mezcla de Biobras-16® más QuitoMax® con este mismo genotipo.

The study was carried out in Los Palacios municipality, with the objective of evaluating the effect of Biobras-16® and QuitoMax® biostimulants on the yield and its components of an advanced line of rice and the commercial cultivar INCA LP-5, as a strategy to increase yields under these soil and climatic conditions. The two genotypes were evaluated with biostimulants independently and the combination of both in two stages of the crop, using doses of 25 mg ha-1 of Biobras-16® and 50 mg ha-1 of QuitoMax®. A completely randomized design with a bifactorial arrangement was used, with eight treatments of three replicates each, and five quantitative traits were evaluated. The data obtained were subjected to univariate statistical analysis. Agricultural yield was higher when genotypes were treated, confirming the potential of Biobras-16® and QuitoMax® to be used as stimulators of this trait in rice cultivation. The best results were achieved with the combinations of Line 1 with QuitoMax® and the mixture of Biobras-16® plus QuitoMax® with this same genotype.
