Description
An account of the resource
Los sistemas silvopastoriles son vistos como una solución factible para la ganadería con enfoque de sostenibilidad. Se destaca que la ganadería contribuye con la seguridad alimentaria, al generar productos alimenticios, empleos e ingresos; sin embargo, también ha generado impactos negativos en el ambiente, como lo son la compactación del suelo, el detrimento de la biodiversidad, la deforestación, la contaminación de fuentes hídricas y la emisión de gases de efecto invernadero, que contribuyen al cambio climático, uno de los inconvenientes ambientales más preocupantes, ya que perjudica a todos los seres vivos del planeta. Por esta razón, se hace indispensable ahondar en el tema de los sistemas silvopastoriles, sus tipos, ventajas y desventajas, con el fin de presentarlos como una alternativa de solución que contribuye con la mitigación del efecto que tiene la ganadería sobre el medioambiente, representando una opción viable para su conservación y adaptación al cambio climático al permitir intensificar la producción ganadera mediante la optimización y uso racional de los recursos naturales.

Fútbol; ¿catalizador de inseguridad? Análisis del fenómeno social y su incidencia en la seguridad

Description
An account of the resource
Desde sus orígenes, el balón pie se ha visto relacionado con la seguridad en varias de sus dimensiones, de manera intrínseca, reciproca e incluso complementaria. Sin embargo, por la popularidad de la cual goza, y su capacidad para conglomerar efervescentes aficionados, se ha malinterpretado su rol dentro de las sociedades donde éste es aceptado. Cabe preguntarse si este catalizador de grandes pasiones resulta entonces una vulneración de dicha seguridad en el desenvolvimiento de sus interacciones. ¿Es el fútbol un generador de violencia? ¿La seguridad se ve afectada por este deporte? La relación de estos dos elementos resulta innegable, evidenciando vulnerabilidades y sensibilidades, por lo cual, este documento pretende analizar su correspondencia, y las externalidades de la misma. Para ello, se realizará un análisis breve de las principales prevaricaciones de la seguridad, y contrastarla con una mirada desde las relaciones generadas a partir de jugadores profesionales que migraron a las ligas más importantes del planeta, producto de la exportación de los mismos al fútbol europeo (puntualmente, Alemania, España, Italia y Portugal). Las cuales como saldo no sólo abren mercados e incentivan la presencia nacional en el viejo continente, sino tienen una serie de repercusiones encarnadas en la labor dentro y fuera de las canchas de cada uno de los jugadores, visibilizando a Colombia dentro de una agenda Soft Power, y retribuyendo beneficios económicos y sociales a sus regiones de origen (escuelas de fútbol, fundaciones, presencia mediática y gubernamental).

Description
An account of the resource
En Colombia, no se han reportado estudios sobre análisis de sendero para maximizar el progreso por selección en el mejoramiento de maracuyá (Passiflora edulis f. flavicarpa Deg.). El estudio tuvo como objetivos realizar dos análisis de sendero, uno para el peso del fruto (PFR) y otro para el peso de la semilla con arilo (PSC) del fruto de maracuyá, bajo las condiciones que presenta la ciudad de Montería (Córdoba, Colombia). Se utilizaron las correlaciones fenotípicas y genéticas originadas del análisis de 400 frutos, obtenidos de diez lotes comerciales, diez plantas / lote y cuatro frutos / planta (repeticiones), bajo un diseño anidado con frutos dentro de planta y plantas dentro de lotes. El análisis de sendero para PFR señaló que los efectos directos fueron positivos y 2,28 a 16,50 veces, los indirectos, cuando se usaron las correlaciones fenotípicas y 1,93 a 6,90 veces cuando se utilizaron las genéticas. El peso de la cáscara (PCA) fue la variable que mostró el mayor efecto directo sobre el PFR. El análisis para el PSC, al utilizar las correlaciones fenotípicas o genéticas, señaló que en el PFR los efectos directos fueron 3,2 a 80 veces los indirectos. El PFR fue la variable que mostró el mayor efecto directo sobre el peso de la semilla con arilo. Los efectos indirectos vía PFR fueron mayores que los directos en todas las otras variables. El peso del fruto, se puede usar como criterio de selección para la obtención de cultivares de alto rendimiento de PSC del fruto en maracuyáIn Colombia, no studies of path analysis to maximize the selection progress in passion fruit (Passiflora edulis f. flavicarpa Deg.) breeding have been reported. The objectives of this work were, therefore, to estimate two path analysis, one for weight per fruit and the other one for seed weight with aril under environmental conditions of the city of Montería (Cordoba, Colombia). Genetic and phenotypic correlations obtained from the analysis of 400 fruits, collected from ten commercial lots, ten plants/lot and four fruits/plant (repetitions) were used under a hierarchical design with plants within lot and fruits within plant. Path analysis for weight per fruit showed that the direct effects were positive and 2.28 to 16.50 times, compared to indirect effects, when phenotypic correlations were used and, 1.93 to 6.90 times, when genetic correlations were employed. Peel weight was the variable that caused the largest direct effect on fruit weight. Path analysis for seed weight with aril, when the phenotypic or genetic correlations were used, showed that in fruit weight the direct effects were 3.2 to 80 times, compared to indirect effects. Fruit weight was the variable that showed the largest direct effect on seed weight with aril. The indirect effects through fruit weight were higher than the direct effects within the other variables. Fruit weight can be used as selection criteria for obtention of passion fruit cultivars of high pulp yield.

Description
An account of the resource
Durante el trienio 1993-1995, se evaluaron el efecto de las asociaciones de maízleguminosas, sobre la conservación de la fertilidad del suelo y su impacto, como cultivos precedentes, sobre el rendimiento del frijol. Se estudiaron en Suelos Oxisoles y en parcelas de escurrimientos (Suelos Ultisoles), las siguientes asociaciones: para el agroecosistema del Sur de La Habana, caracterizado por suelos ultisoles (parcelas de escurrimiento): maíz; maíz+caupí; maíz+frijol de terciopelo; maíz+canavalia; maíz+crotalaria; maíz+sesbania. Para el agroecosistema de San Juan y Martínez: maíz; maíz+caupí; maíz+frijol de terciopelo; maíz+canavalia; millo y barbecho. Los resultados señalaron que las asociaciones del maíz con leguminosas beneficiaron las propiedades del suelo evaluadas, y que combinadas con el laboreo mínimo, en las condiciones de los suelos Oxisoles, complementaron el efecto benéfico de éste. El impacto de estas coberturas como precedente del cultivo del frijol fue significativo sobre su rendimiento con respecto al maíz solo.El balance de los nutrimentos se vio favorecido por el reciclaje efectuado por los abonos verdes utilizados, con la reducción del nitrógeno en hasta un 25 %, y en un 100 % para el P2O5 y K2O, teniendo en cuenta el alto abastecimiento de estos suelos. En los Ultisoles donde se establecieron las coberturas en parcelas de escurrimiento, además de repetirse los efectos de éstas, se vio el impacto antierosivo de las mismas, al disminuir las pérdidas de suelos con respecto al barbecho y al testigo con maíz solo.

An account of the resource
Embryogenic yam (Dioscorea rotundata) cultures were induced from petioles of leaves of in vitro grown plants on medium supplemented with different 2.4-D concentrations. Cultures were maintained either on semisolid or in liquid MS medium supplemented with 4.52 µM 2.4-D. The effect of sucrose concentration on somatic embryo development was also evaluated and the effects of different BAP concentrations on somatic embryo conversion were determined. Treatments were distributed using a complete randomized design. The highest rate of induction occurred with 4.52 µM 2.4-D. Sucrose at 131.46 mM significantly enhanced somatic embryo development. The conversion rate was not affected by BAP.Cultivos embriogénicos de ñame (Dioscorea rotundata) fueron inducidos a partir de explantes consistentes de hojas con peciolos, aisladas de plantas establecidas en condiciones in vitro, en presencia de diferentes concentraciones de 2,4-D. Los cultivos inducidos fueron mantenidos en medio MS líquido o semisólido suplido con 4,52 µM 2,4-D. El efecto de las concentraciones de sacarosa sobre el desarrollo de embriones somáticos y el efecto de varias concentraciones de BAP sobre la tasa de conversión de embriones somáticos en plantas también fueron evaluados. Todos los tratamientos fueron distribuidos usando un diseño completamente al azar. El mayor porcentaje de inducción de tejidos embriogénicos ocurrió con 4,52 µM de 2,4-D. La adición de 131,46 mM de sacarosa incrementó significativamente el desarrollo de embriones somáticos. La tasa de conversión de embriones somáticos en plantas no fue afectada por las concentraciones de BAP.

A utilização de resíduos animais provenientes da avicultura como fertilizante orgânico é uma maneira sustentável de utilização dos resíduos desse sistema de produção, porém ainda há poucos estudos sobre a dinâmica de disponibilização dos nutrientes. O objetivo deste trabalho foi avaliar o uso de cama de aves associada à fertilizante nitrogenado na cultura do milho e a disponibilização de nitrogênio da cama de aves durante três anos de cultivo. Foi utilizado o delineamento em blocos casualizados, no esquema fatorial 3x5+1. Os fatores consistiram doses de cama de aves (2, 5 e 8 Mg ha-1) e doses de nitrogênio (0, 50, 100, 150, 200 kg ha-1). A testemunha recebeu fertilizante mineral na semeadura na dose de 120, 80 e 20 kg ha-1 de P205, K2O e N, respectivamente e em cobertura com 200 kg ha-1 de N. Foram feitas leituras com clorofilômetro, altura de plantas, altura de espigas, produtividade, massa de cem grãos e número de grãos por espiga. As maiores doses de cama de aves utilizadas em três anos sucessivos, mesmo sem N em cobertura, propicia produtividade semelhante à testemunha com fertilizante mineral na cultura do milho. A cama de aves é alternativa viável na adubação da cultura do milho.
