In Mexico, the relationship of seed size with the productive and nutritional potential of maize silage needs to be studied. Thus, this study investigated the effect of seed size on yield and the nutritional value at the cutting stage for silage of various maize varieties. The research consisted of two phases: the productivity of maize for silage and the nutritional value estimated in the laboratory. Nine maize varieties, previously classified by their seed size, were used: flat large and flat medium. The experimental design was a randomized complete block with factorial arrangement and four repetitions. The harvest was carried out at the silage-cutting stage (30-35% DM, whole plant). Results for each estimated variable showed significant differences (P<0.001) among varieties, while seed size was significant for only some variables. Based on the absolute value of the standardized coefficients, the outstanding variables were female flowering, total protein, in vitro digestibility, and dry matter yield. In conclusion, maize variety for silage affects the productivity and nutritional value in the cutting stage. In contrast, the effect of seed size on protein yield, protein content, and plant digestibility was minor. The materials Campeón, H-135, H-157, HS-2, and A-791 yielded the highest, while the nutritional value of H-135, Campeón, HS-2, VS-22, and H-358 was outstanding.

Abstract: (spanish)
En México la relación que el tamaño de semilla tiene con el potencial productivo y nutricional del maíz para ensilado no se ha estudiado. El objetivo fue determinar si el tamaño de semilla influye sobre el rendimiento y el valor nutricional en la etapa de corte para ensilado en diferentes variedades de maíz. La investigación consistió en dos fases: en la primera, se evaluó la productividad del maíz para ensilado y en la segunda, se determinó el valor nutricional en laboratorio. Se utilizaron nueve variedades de maíz previamente clasificados en dos tamaños de semilla: plano grande y medio. El diseño experimental utilizado en cada fase fue bloques completos al azar con arreglo factorial y cuatro repeticiones. La cosecha se realizó en la etapa de corte para ensilado (30-35% MS, planta completa). Hubo diferencias significativas (P<0.001) en todas las variables evaluadas para variedades; en tamaño de semilla solo hubo significancia en algunas variables. En función del valor absoluto de los coeficientes estandarizados, las variables relevantes fueron floración femenina, proteína total, digestibilidad in vitro y rendimiento de materia seca. Se concluye que la variedad afecta la productividad y el valor nutricional en la etapa de corte del maíz para ensilado; mientras que el tamaño de semilla, sólo presentó un ligero efecto en el rendimiento de proteína por hectárea, contenido de proteína y en la digestibilidad de la planta. Los materiales Campeón, H-135, H-157, HS-2 y A-791 fueron los de mayor productividad y en cuanto al valor nutricional estuvieron H-135, Campeón, HS-2, VS-22 y H-358. PALABRAS-CLAVES: .
