Evaluación de la transición agroecológica de un establecimiento ganadero a base de pastizal de la cuenca del Salado, mediante indicadores = Evaluation of the agroecological transition through indicators of a livestock establishment based on native grasslands of the Salado basin
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-06)Son muy escasas las experiencias documentadas de manejos agroecológicos en sistemas extensivos de zonas templadas, en particular las que contemplen la utilización de pastizales naturales. Por ello nos propusimos evaluar ... -
Exposure to toxic fescue during late gestation on beef cows: effects on cow performance and offspring performance from birth to weaning
(ECronicon Open Access, 2020-01-03)To examine the effects of endophyte-infected tall fescue during late gestation on maternal and offspring performance, multiparous Angus cows (n = 40) were bred via AI and allocated into grazing treatments: toxic (E+) or ... -
Frequency of Neospora caninum infections in beef cow–calf operations under extensive management
(2016-03-30)The aim of this study was to evaluate the frequencies of Neospora caninum horizontal and vertical transmissions in beef cow–calf operations under three different extensive management systems: group A: 0.75 head per hectare ... -
Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season
(2018-08-01)Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ... -
Growth, nutrient uptake and symbiosis with rhizobia and arbuscular mycorrhizal fungi in Lotus tenuis plants fertilized with different phosphate sources and inoculated with the phosphate-solubilizing bacterium Pantoea eucalypti M91
(2014-12)Background and aims: The aim of this work was to evaluate the ability of P fertilization and phosphate-solubilizing bacteria (PSB) inoculation to promote the growth of L. tenuis in typical soils of the Salado River Basin ... -
Herbicide-mediated promotion of Lotus tenuis (Waldst. & Kit. ex Wild.) did not influence soil bacterial communities, in soils of the Flooding Pampa, Argentina
(2016-02)Promoting the forage Lotus tenuis is an appealing alternative to meet the needs for cattle production in the Flooding Pampa region, Argentina. This agricultural practice requires herbicides application to remove plant ... -
Hydraulic conductivity and pore connectivity. Effects of conventional and no-till systems determined using a simple laboratory device
(Elsevier, 2019-03-01)Soil hydraulic conductivity is a property that describes how easily water can move through a porous space and its determination is important because it controls many soil hydrological processes. The objectives of this work ... -
Impact of dairy farms on groundwater quality in a productive basin in the northeast of the Pampean Plain, Argentina
(Elsevier, 2023-11)The Pampean Plain is a relevant world food production area where livestock and agricultural activities are developed. The northeast of this region is characterized by dairy production, where large quantities of excreta ... -
Impacto del tránsito en dos sistemas de siembra
(2015-12)Los sistemas productivos agrícolas presentan altos niveles de mecanización con tractores y máquinas cada vez más pesados. Como consecuencia, la compactación de los suelos es un problema emergente, dando como resultado el ... -
Late-gestation protein restriction negatively impacts muscle growth and glucose regulation in steer progeny
(Elsevier, 2019)The objective of this study was to determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes in glucose and insulin concentrations. At 129 d of gestation, ... -
Maize Physiological Responses to Heat Stress and Hormonal Plant Growth Regulators Related to Ethylene Metabolism
(2013-07)Hormonal plant growth regulators (HPGRs) have been evaluated in field grown maize (Zea mays L.), but never as a tool for prevention or mitigation of heat stress. We analyzed grain yield determination of maize crops exposed ... -
Mejora de propiedades físicas por el uso de especies megatérmicas en un suelo sódico templado
(2015-06)Las especies megatérmicas pueden disminuir el pH del suelo y los niveles de sodicidad cuando se implantan en suelos sódicos, pero poco se sabe acerca de su capacidad para mejorar la condición física de suelos sódicos ... -
Morpho-physiological responses of tall wheatgrass populations to different levels of water stress
(Plos One, 2018-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a perennial forage grass cultivated in dry, saline or alkaline environments. The morpho-physiological characteristics of four populations of tall ... -
Morpho‐physiological, biochemical and isotopic response of tall wheatgrass populations to salt stress
(Wiley, 2020-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a C3 grass native from dry or saline habitats in SE Europe. The aim of this study was to better understand response mechanisms of populations from ... -
Persistencia de los efectos de la descompactación del suelo con paratill
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-07)En la Argentina predomina como sistema productivo la siembra directa donde la ausencia de remoción y el tránsito de máquinas cada vez más pesadas han incrementado los problemas de compactación. Para revertir este fenómeno ... -
Phosphorus fertilization of a grass-legume mixture: effect on plant growth, nutrients acquisition and symbiotic associations with soil microorganisms
(2015-09)Adding P on Lotus tenuis and Festuca arundinacea, pure or mixed, on growth, nitrogen (N) and phosphorus (P) acquisition and associations with soil microorganisms was studied to investigate the establishment of Lotus for ... -
Producción de biomasa, cobertura y calidad forrajera de Chloris gayana y Panicum coloratum en un suelo alcalino sódico de la Depresión del Salado
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)La expansión agrícola, que viene ocurriendo en la región durante las últimas dos décadas, no solo redujo considerablemente la superficie ganadera, sino que la desplazó hacia zonas marginales. En este contexto, la incorporación ... -
Promotion of Lotus tenuis and calf early weaning as a good management practice for breeding herds in marginal soils of the Flooding Pampa (Argentina)
