| Summary, etc |
La presente investigación se realizó en el municipio de Chiquimulilla, departamento de Santa Rosa, con el objetivo de evaluar la influencia del potasio y del azufre sobre el rendimiento del arroz (Oryza sativa L.) y su incidencia económica. Se utilizó un diseño experimental de bloques completos al azar con diferentes niveles de aplicación de ambos nutrientes. Se midieron variables de crecimiento, rendimiento y rentabilidad. Los resultados mostraron que las dosis combinadas de potasio y azufre incrementaron significativamente la producción de grano y mejoraron la eficiencia económica del cultivo, evidenciando la importancia de una fertilización balanceada para optimizar los rendimientos. |
