Title A name given to the resource Efectos de sistemas parciales de agricultura biológica y convencional (local) en la fertilidad de suelos y en la producción de frijol en Villanueva (Santander, Colombia). Ciclo II Effects of organic and conventional partial farming system on soil fertility and bean yield in Villanueva (Santander, Colombia) Creator An entity primarily responsible for making the resource León Sicard Tomás Enrique, Cortés Julio Enrique Description An account of the resource Se comparó el efecto en la fertilidad del suelo y en la producción de fríjol (Phaseolus vulgaris) x millo (Sorghum sp.) de sistemas parciales de agricultura biológica y convencional (local), durante 3 semestres (1995A-1996A), utilizando un arreglo de parcelas divididas y un diseño en bloques completos al azar con 3 replicaciones, en el que la Parcela Mayor fue el tipo de manejo de plagas (biológico o químico), la Subparcela fue el arreglo de cultivo (asocio vs cultivo) y la Sub-subparcela fue el tipo de fertilización química vs abonamiento orgánico. En ninguno de los tres semestres se presentaron diferencias significativas entre los rendimientos de fríjol por efecto de los tipos de agricultura, confirmando resultados anteriores de 1994A y B. Durante 1995B, los rendimientos del millo fueron significativamente superiores en el sistema biológico, debido probablemente, a efectos edáficos. Los Indices de Uso Eficiente de la Tierra (IET) fueron superiores a 1 en toda la experiencia, indicando el efecto positivo del asocio. Se constataron incrementos en acidez, capacidad de intercambio catiónico, bases totales y saturación total del suelo en todas las parcelas, que incidieron para que su fertilidad global aumentara de baja a moderada.&lt;br /&gt;The effects of organic versus conventional farming methods in soil fertility and intercropping yields (Phaseolus vulgaris x Sorghum sp.) was studied throughout three growing seasons (1995A-1996A). The methodoly used to conduct the study was to divide the field into parcels, aplying natural vs chemical disease controls, monoculture vs intercropping and manure vs chemical fertilizers. As well as other experience carried out in 1994, neither bean growing season presented significant differences between the two agricultural systems, although the yield of sorghum in the organic farming system was superior to that of the conventional system during 1995B, probably due to edaphic effects. The Efficient Land Use Index&lt;br /&gt;(IET) were superior to 1 during all over the experience, showing the benefits of the intrercropping systems. There was increases on pH, exchangecationiccapacity,totalcations and total soil saturation that also increasedsoil fertility from lower to medium levels in both organical and conventional systems.&lt;br /&gt; Date A point or period of time associated with an event in the lifecycle of the resource 1998 Subject The topic of the resource Propiedades físicas del suelo, cultivos asociados (fríjol x millo), erosion, propiedades químicas del suelo, sistemas de producción, índice de uso eficiente de la tierra Source A related resource from which the described resource is derived Agronomía Colombiana Publisher An entity responsible for making the resource available Centro Editorial of Facultad de Ciencias Agrarias, Universidad Nacional de Colombia Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Plant ecology Relation A related resource <a href="http://www.revistas.unal.edu.co/index.php/agrocol/article/view/21533" target="_blank" rel="noreferrer noopener">http://www.revistas.unal.edu.co/index.php/agrocol/article/view/21533</a>
