| dc.description | The cultivation of rice (Oryza sativa) is one of the main foods in the food basket and as an economic base of many countries, it generally faces multiple bacterial diseases, such as Piricularia, sheath blight and bacterial blight - they greatly affect the production and quality of the product, on the other hand, the high excess of iron in the soil generates serious damage to the development of the plant, due to this the need to look for sustainable solutions for our cultivation. This study investigated the effects caused by Trichoderma, for this purpose ten treatments were applied with various combinations of Trichoderma and Silicon, evaluating factors related to plant growth, production and soil-microbiological analysis. The results indicate that applications of 500 g/ha of Trichoderma + 75 kg/ha silicon gave taller plants, a greater number of tillers and panicles, longer panicles and a greater number of grains; and higher grain yield, with 63% above the farmer control. The applications of Trichoderma in different doses increase the concentration of spores, using 500 g/ha of Trichoderma, 79% more is obtained in relation to the farmer control. In addition, these tend to stabilize nutrients that are toxic in the soil such as Copper, Iron and Manganese, which decreased on average by 45% compared to the control. | es_ES |

| dc.description.abstract | El cultivo de arroz (Oryza sativa) es uno de los principales alimentos en la canasta en la alimentacion y como base economica de muchos paises, por lo general enfrenta multiples enfermedades bacerianas, como Piricularia, tizón de la vaina y añublo bacteriano- afectan en gran manera la produccion y la calidad del producto, por otra parte el alto exeso de hierro en los suelos genran grabes daños en el desarrollo de la planta, devido a esto surgue la necesidad de buscar soluciones sostenibles para nuestro cultivo. Este estudio investigó los efectos que causa Trichoderma, con este fin se aplicaron diez tratamientos con varias combinaciones de Trichodermas y Silicio, evaluando factores relacionados con el crecimiento de las plantas, produccion y analsisis de suelo-microbiologico. Los resultados indican que las aplicaciones de 500 g/ha de Trichoderma + 75 kg/ha silicio dieron plantas más alta, mayor cantidad de macollos y panículas, panículas más largas y con mayor cantidad de granos; y mayor rendimiento de grano, con 63% por encima del testigo agricultor. Las aplicaciones de Trichoderma en diferentes dosis elevan la concentración de esporas, utilizando 500 g/ha de Trichoderma se obtiene 79% más con relación al testigo agricultor. Ademas estas tienden a estabilizar los nutrientes que son tóxicos en el suelo como Cobre, Hierro y Manganeso; los cuales disminuyeron en promedio un 45% con relación al testigo. | es_ES |
