| description |
In Colombia, the increase of barley production is restricted by such factors as irregular rainfall, low temperatures, soil acidity, low fertility and disease, associated with improper soil management and scarse improve germoplasm, A suitable use of fertilizers is an alternative to face part of the problem by means of plant breeding in different terrain, tend to develop of low soil productivity tolerant cultivars. To arrive at appropiate recommendations for farmers, it was consider the quantity of removal nutrients at physiological maturity. The 124 commercial barley preferred moderately fertil soils but with a lower nutritional efficiency after a commercial cultivar wheat. Its nutritional requirements to reach a 2.5 t/ha yield without irrigation was: Macronutrientes (kg/ha): 30 N, 8 P, 24 K, 8 Ca, 2.5 Mg; Micronutrients (g/ha): 140 Mn, 40 Zn, 24 Cu, 340 Fe. For many new barley cultivars sowed over ondulating terrains, the highest nutritional efficiency was in a Vertic Tropudalf, moderately behavoir in the Paralithic Humitropept and the lowest in an Ustic Dystropept. There were two cultivars with low adaptation, only one grow well in a difficult terrain and three cultivars exhibit good adaptation in all studied terrains. |

Una alternativa para enfrentar parte del problema está en la selección de líneas en diferentes terrenos, tendiente a desarrollar variedades adaptables aún a suelos de baja productividad. Para llegar a una apropiada recomendación a los agricultores se consideró la cantidad de nutrientes removidos por las plantas en madurez fisiológica. La cebada comercial 124 mostró preferencias por suelos de moderada fertilidad pero tuvo una relativa menor eficiencia en la conversión de nutrientes a grano frente al trigo Bonza. Sus requerimientos nutricionales para alcanzar rendimientos cercanos a 2.5 t/ha sin riego se definieron así: Macronutrientes (kg/ha): 30N, 8P, 45K, 8Ca, 2.5 Mg; Micronutrientes (g/ha): 140 Mn, 40 Zn, 24 Cu, 340 Fe. La más alta eficiencia nutricional para varias líneas promisorias de cebada sembradas en terrenos ondulados se dió en el suelo más productivo pero arcilloso (Vertic Tropudalf), una respuesta intermedia se halló en uno humífero ácido poco profundo (Paralithic Humitropept) y una muy baja eficiencia se reportó en el de menos retención de humedad e infértil (Ustic Dystropept). Se seleccionaron dos líneas con baja adaptación a los tres terrenos mencionados, una rindió bien en el ambiente más difícil, y tres líneas exhibieron alta adaptación a todos los terrenos escogidos.application/pdfspaUniversidad Nacional de Colombia Sede Palmirahttp://revistas.unal.edu.co/index.php/acta_agronomica/article/view/15542Universidad Nacional de Colombia Revistas electrónicas UN Acta AgronómicaActa AgronómicaMadero Morales, Edgar Enrique and Amézquita Collazos, Edgar (1993) Nutrient uptake by barley in six colombian soils.
