Pre-harvest strategy for reducing aflatoxin accumulation during storage of maize in Argentina
(Elsevier, 2022-08-27)Maize (Zea mays L.) is an important crop in Argentina. Aspergillus flavus may infect this crop at growing stage and the harvested kernels can be contaminated with aflatoxins (AFs), whose levels may increase during storage. ... -
Predicción de contenido de arcilla superficial utilizando conductividad eléctrica aparente y esquemas de muestreo basados en modelos
(2017)La predicción espacial del contenido de arcillas (As) a escala de lote es requerida para la implementación de agricultura de precisión y modelos de simulación hidrológica. Sin embargo, la brecha de técnicas de cartografía ... -
Predicting maize phenology: intercomparison of functions for developmental response to temperature
(American Society of Agronomy, 2014-12)Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision ... -
Predicting soybean losses using carbon dioxide monitoring during storage in silo bags
(Elsevier, 2019-06)The rapid increase of the overall grain production of Argentina resulted with a storage capacity deficit in permanent structures of 40–50 million tons, and this context favored the rapid adoption of the silo bag technology. ... -
Prediction of topsoil properties at field-scale by using C-band SAR data
(Elsevier, 2020-07-10)Designing and validating digital soil mapping (DSM) techniques can facilitate precision agriculture implementation. This study generates and validates a technique for the spatial prediction of soil properties based on ... -
Presence of pesticides in surface water from four sub-basins in Argentina
(Elsevier, 2014-07)Argentina has 31 million hectares given over to agriculture comprising 2.2% of the world’s total area under cultivation (Stock Exchange of Rosario, Argentina). Despite the intensity of this agricultural activity, data on ... -
Prevalence of Escherichia coli strains in horticultural farms from Argentina: antibiotic resistance, biofilm formation, and phylogenetic affiliation
(Springer, 2022-04)Escherichia coli is the bacteria most commonly used as an indicator of fecal contamination in agricultural environments. Moreover, E. coli is categorized as a priority pathogen due to its widespread antibiotic resistance. ... -
Proceso de institucionalización de la agricultura familiar y nuevo referencial para el desarrollo rural en la Argentina
(2015-04)Este artículo pone en relieve las ideas y los intereses políticos y económicos que condujeron a la reciente institucionalización de la agricultura familiar en la Argentina. Este sector, que fue motor de la primera ... -
A process-based numerical approach to estimate forest groundwater consumption in flatland petrocalcic soils
(International Water Association Publishing, 2019-11-01)Grasslands are extensively distributed in flatland areas around the world such as the Pampas in South-America. It is one of the most economically productive landscapes and, as in other regions, they are being replaced by ... -
Producción de forraje de agropiro alargado en función de la disponibilidad de nitrógeno y la posición topográfica
(2017)El objetivo fue evaluar, en diferentes posiciones topográficas, el crecimiento de agropiro alargado (Thinopyrum ponticum [Podp.] Barkworth & D. R. Dewey Phil) bajo diferente disponibilidad de nitrógeno (N). Se seleccionaron ... -
Producción potencial de semillas por planta en especies de Bromus (Sección Ceratochloa), en el sudeste de la provincia de Buenos Aires = Potential seed production per plant in species of Bromus (Section Ceratochloa) at southeast of Buenos Aires province
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2016)En Argentina crecen varias especies de la Sección Ceratochloa del género Bromus, que se destacan por su producción de forraje inverno-primaveral. El valor de estos recursos nativos ha incentivado la colecta de semillas de ... -
Production of a bovine IL-12p40 probe and application using in situ hybridization on ruminant fixed tissues
(Elsevier, 2013-02-15)Pro-inflammatory cytokines (particularly IL-12) are important for initiating protective T helper 1 (Th1)-type immune responses and hence vital for combating intracellular infections and tumours. In situ hybridization (ISH) ... -
Production of fodder in a treeless system and in silvopastoral system in central Argentina
(Instituto de Florestas da Universidade Federal Rural do Rio de Janeiro, 2019-01-31)This paper aims to identify the spatial and temporal distribution of net aerial primary production (NAPP) of oats and sorghum in silvopastoral systems (SPS) and in a treeless situation (TLS), in Southern Cordoba, Argentina. ... -
Productive response to two concentrate allocation strategies in dairy cows grazing with restricted pasture allowance
(2019-02)The objective of this study was to compare the effects of two concentrate allotment strategies on the performance of dairy cows grazing on restricted pasture and supplemented with conserved forage. Dairy cows fed equal ... -
Prognosis and diagnosis of sulfur status in maize by plant analysis
(Elsevier, 2019-05)The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ... -
