Gas production kinetics and in vitro degradability of tannin-containing legumes, alfalfa and their mixtures
(Elsevier, 2019-06)The aim of this study was to determine in vitro ruminal degradability and gas production kinetics of sainfoin (Onobrichis viciifolia; SF), birdsfoot trefoil (Lotus corniculatus; BFT), alfalfa (Medicago sativa L.; ALF) and ... -
Decomposition from legume and non-legume crop residues: effects on soil organic carbon fractions under controlled conditions
(Sociedad Española de la Ciencia del Suelo, 2017)Cover crop (CC) residues protect the soil from erosion and their permanence on the surface is largely influenced by their biochemical constituents. We performed a study under controlled conditions to investigate the dynamics ... -
Modeling Avena fatua seedling emergence dynamics: an artificial neural network approach
(Elsevier, 2012-10)Avena fatua is an invasive weed of the semiarid region of Argentina. Seedling emergence patterns are very irregular along the season showing a great year-to-year variability mainly due to a highly unpredictable precipitation ... -
Calidad de cultivos de cobertura en sistemas de siembra directa del sudoeste bonaerense
(Asociación Argentina Ciencia del Suelo, 2017-12)El sistema de siembra directa con cultivos de cobertura (CC) de otoño/invierno asegura proveer elevadas cantidades de di- ferentes tipos de residuos orgánicos al suelo. La composición bioquímica de cada residuo, en especial ... -
Determinación de la superficie bajo riego con pivot central en el sudoeste de la Provincia de Buenos Aires [Argentina] utilizando imágenes satelitales
(Universidad de Buenos Aires, 2015)Se efectuó un relevamiento de la superficie regada con pívot central en nueve partidos del sudoeste bonaerense para la campaña agrícola 2013/14. Para ello se han empleado técnicas de teledetección, utilizando el satélite ... -
Natural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
(2018)Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), ... -
Modelación productiva, económica y emisión de metano en sistemas de cría vacuna de Bahía Blanca y Coronel Rosales
(2018-08)El objetivo de este estudio de simulación fue evaluar la respuesta productiva, económica, emisión de metano y el valor marginal del agregado de alimento extra (VMA) en diferentes sistemas la cría vacuna de Bahía Blanca y ... -
Seed germination of five Prosopis shrub species (Fabaceae-Mimosoideae) from the Monte and Patagonia phytogeographic provinces of Argentina
(2017-12)The Patagonian species of the genus Prosopis exhibit distinctive features such as their shrub growth pattern. However, morphological or physiological differences among them have been poorly studied (e.g., germination). ... -
Operational planning of herbicide-based weed management
(2013-10)Weeds cause crop yield loss due to competition, interfere with agricultural activities and reduce grain quality due to seed contamination. Among the numerous methods for weed control, the use of herbicides is the most ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
(2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Feeding value of whole raw soya beans as a protein supplement for beef cattle consuming low‐quality forages
(2018-02)Experiments (Exp) I and II were conducted to compare raw whole soya beans (WSB), roasted (rWSB) or other protein sources as supplements of low‐quality forages fed ad libitum to beef cattle, upon DM intake (DMI), ruminal ... -
How leaf rust disease and its control with fungicides affect dough properties, gluten quality and loaf volume under different N rates in wheat
(2018-03)The unique viscoelastic properties of gluten make bread wheat (Triticum aestivum L.) a staple food. The specific balance between gluten fractions, together with grain protein content (GPC), defines nutritional and end-use ... -
Soil physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
(2018-09)This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ... -

(2014-12)La utilización de cultivos de cobertura (CC) tiene efecto sobre la acumulación de N y rendimiento de los cultivos sucesores. El objetivo de este trabajo fue evaluar la producción, los componentes del rendimiento y acumulación ... -
Changes in Weed Communities of Spring Wheat Crops of Buenos Aires Province of Argentina
(2014-03)During 2004 to 2008, weed surveys were conducted in 373 wheat fields of two different cropped areas (southwest [SW] and southeast [SE]) of the southern region of Buenos Aires Province of Argentina where different weed ... -
A new formulation of oxalic acid for Varroa destructor control applied in Apis mellifera colonies in the presence of brood
(2016-07)An organic product based on oxalic acid was evaluated for use in Varroa control under spring/summer climatic conditions in Argentina. The formulation consists of four strips made of cellulose impregnated with a solution ... -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
(2018-06)Most popular emergence prediction models require species-specific population-based parameters to modulate thermal/hydrothermal accumulation. Such parameters are frequently unknown and difficult to estimate. Moreover, such ... -
El cultivo de trigo en la región semiárida bonaerense: impacto sobre algunas propiedades químicas del suelo
