Lilia Salas Pérez CANDIDO MARQUEZ HERNANDEZ JOSUE RAYMUNDO ESTRADA ARELLANO JUAN RAMON ESPARZA RIVERA (2016)

The objective of this study was to determine the proportion of sand, solarized manure, vermicompost and soil capable of increasing tomato fruit yield and lycopene content. The treatments were: T1: 80 % Sand- 20 % Vermicompost (SV), T2: 80 % Sand- 20 % Solarized manure (SSM1), T3: 80 % Sand - 20 % Pelite ?Steiner solution (SPSS), T4: 80 % Sand- 5 % Soil - 15 % Vermicompost (SSoV), T5: 85 % Sand - 15 % Solarized manure (SSM2) and T6: 80 % Sand - 5 % Soil - 15 % Solarized manure (SSoSM). The organic substrates T5, T4, T1 and the control (T3) obtained larger fruits and yields. The lycopene content in tomato fruits grown in the organic substrates was 26 % higher than that obtained in the control treatment. Organic fertilizers improve the nutraceutical quality of tomato fruits, without signi cantly degrading yield.

Cambios estacionales en la concentración de azúcares solublesen órganos perennes de nogal [(Carya illinoiensis(Wangenh.) Koch)]

Seasonal changes in soluble sugar concentration in pecan perennial organs(Carya illinoiensis[Wangenh.] Koch)

El transporte de azúcares de tejidos de asimilación a tejidos de reserva determina el crecimiento o el almacenamiento reproductivo vegetal. El objetivo fue determinar las concentraciones de azúcares solubles en nogal pecanero crecidos en una huerta ubicada en Torreón, Coahuila, durante las etapas de producción y letargo. Se tomaron muestras de raíz, tallo, rama y brote emitido del año (crecimiento anual) en cuatro árboles adultos. Durante el letargo se observaron mayores concentraciones de azúcares solubles que durante la etapa de producción. La raíz y los brotes anuales tuvieron concentraciones similares, más altas que los otros dos órganos. La menor concentración se encontró siempre en las ramas. El tallo presentó una concentración similar a las ramas durante la etapa de producción, mientras que, en la etapa de letargo, el tallo tuvo mayor concentración de azúcares que las ramas. A pesar de que la raíz presenta las mayores concentraciones de azúcares solubles, el tallo, por su tamaño, acumula la mayor cantidad de azúcares totales a nivel de todo el árbol. Se estimó que el porcentaje de los azúcares solubles del total del carbono contenido en la biomasa representa un valor porcentual de 66%

Transport of sugars from assimilation tissues to reserve tissues determines growth or reproductive storage. The objective wasto determine the concentrations of soluble sugars in pecan tree grown in an orchard located in Torreón, Coahuila, during the stages of production and dormancy. Samples of root, stem, branch, and bud emitted from the year (annual growth) were taken from fouradult trees. During the dormancy higher concentrations of soluble sugars were observed than during the production stage. Rootand annual outbreaks had similar concentrations, higher than the other two organs. The lowest concentration was always found in branches. Stem had a concentration similar to the branches during the production stage, while in the dormant stage, the stem had ahigher concentration of sugars than the branches. Although the root has the highest concentrations of soluble sugars, the stem, by its size, accumulates the greatest amount of total sugars in the whole tree. It was estimated that the percentage ofsolublesugars of the total carbon contained in the biomass represents a percentage value of 66%.

EFECTO DEL LIXIVIADO DE VERMICOMPOSTA EN LA PRODUCCIÓN HIDROPÓNICA DE MAÍZ FORRAJERO

Effect of Vermicompost Lixiviate on the Production of Hydroponic Corn Forage

PABLO PRECIADO RANGEL JOSE LUIS GARCIA HERNANDEZ MIGUEL ANGEL SEGURA CASTRUITA LILIA SALAS PEREZ ALMA VELIA AYALA GARAY JUAN RAMON ESPARZA RIVERA ENRIQUE TROYO DIEGUEZ (2014)

"En zonas áridas, la ocurrencia de sequías colapsa con frecuencia la producción ganadera debido a la consecuente escasez de forrajes, por lo que resultan relevantes el diseño y aplicación de nuevos esquemas de producción forrajera. En este trabajo se comparó el rendimiento y calidad nutrimental de forraje verde hidropónico de maíz fertilizado con dos soluciones nutritivas: una convencional o inorgánica (SNC) y otra orgánica (SNO) formulada a base de lixiviado de vermicomposta, más tratamiento testigo sin fertilizar (agua potable). Catorce días después de la siembra se evaluaron variables de respuesta: altura de planta, conversión semilla-forraje, uso eficiente de agua, rendimiento en peso fresco, materia seca, proteína cruda, fibra ácido detergente y fibra neutro detergente. Se concluye que ambas soluciones nutritivas favorecieron el rendimiento y calidad nutrimental de plantas de maíz forrajero en comparación con el tratamiento testigo; asimismo, el lixiviado de vermicomposta, en virtud de que mostró resultados estadísticamente similares a la SNC, representa una alternativa sustentable para la producción de forraje verde hidropónico de maíz en zonas áridas."

"In arid zones, the occurrence of droughts cause livestock production to collapse because of the consequent scarcity of forage; hence, the design and application of new forage production schemes gains relevance. This work assessed the yield and nutrimental quality of green hydroponic corn forage fertilized with nutrient solutions, conventional, or inorganic (SNC), one organic solution (SNO), whose formulation was based on a vermicompost lixiviate, and a control treatment without fertilization (potable water). Fourteen days after sowing, response variables were assessed: plant height, fresh weight, seed-forage conversion, dry matter, water use efficiency, crude protein content, acid detergent fiber, and neutral detergent fiber. It was concluded that both nutrient solutions favored yield and nutrimental quality of corn plants, as compared with the control treatment. Also, the vermicompost lixiviate showed results statistically similar to the SNC and thus can be considered a sustainable option for the production of green hydroponic corn forage in arid zones."
