dc.description | The janeiro grass (Eriochloa polystachya Kunth) is a species used in forage with
appropriate characteristics to thrive in marginal conditions that needs to be improved in
its nutritional value or other agronomic characteristics. Gamma rays can be used for the
genetic improvement of plants and generate mutations that can be useful. The
investigation was carried out with the objective of determining the best cutting season.
The study was carried out in the field of the Faculty of Agricultural Sciences of the
Technical University of Babahoyo. Five doses were evaluated 0; 25; 50; 75 and 100 Co60
gamma ray gray. Two cutting times 25 and 40 days after the equalization cut and two
doses of fertilization with N-P-K were evaluated. A randomized complete block design
with factorial arrangement (DBCA) was used, which was contrasted with the Tukey test
at 95% probability, with the InfoStat statistical package. The dry matter percentages were
26.48 at 25 days and 22.25 at 40 days, the averages were for branch length 1.94 meters,
leaf length and leaf width 30.76 cm and 1.82 cm respectively, the best percentage of
protein being I present the witness with 12.29% | es_ES |

dc.description.abstract | El pasto janeiro (Eriochloa polystachya Kunth) es una especie empleada en forraje con características apropiadas para prosperar en condiciones marginales que requiere ser mejorada en su valor nutricional u otras características agronómicas. Los rayos gamma se pueden utilizar para el mejoramiento genético de las plantas y generar mutaciones que puedan ser útiles. La investigación se realizó con el objetivo de determinar la mejor época de corte. El estudio se realizó en campo de la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Babahoyo. Se evaluaron cinco dosis 0; 25; 50; 75 y 100 Gray de rayos gamma Co60. Se evaluó dos épocas de corte 25 y 40 dias después del corte de igualación y dos dosis de fertilización con N-P-K. Se utilizó un diseño de bloques completos al azar con arreglo factorial (DBCA) los cuales fueron contrastados con la prueba de Tukey al 95 % de probabilidad, con el paquete estadístico InfoStat. Los porcentajes de materia seca fueron de 26.48 a los 25 dias y de 22.25 a los 40 dias, los promedios fueron para longitud de rama 1.94 metros, longitud de hoja y ancho de hoja 30.76 cm y 1.82 cm respectivamente, el mejor porcentaje de proteína lo presento el testigo con 12.29 %. | es_ES |
