Se trabajó con muestras aleatorias de 15 huevos de ... -
Variabilidad, tendencia y eventos extremos en los rendimientos agrícolas a nivel de partidos en la Provincia de Buenos Aires
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-06-09)Climate variability is the main determinant of fluctuations in the productive and economic results of agriculture. Due to Climate Change, extreme events are expected to occur with greater frequency and intensity in the ... -
Fin de las reservas de fertilizantes fosfatados: ¿realidad o restricciones geopolíticas?
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2022-08-30)El fósforo (P) es un elemento fundamental para toda la vida en la tierra, y no presenta un sustituto en la producción de alimentos. El suministro de P desde las reservas de rocas fosfóricas está concentrado en unos pocos ... -
Efecto del secado y manejo agronómico sobre propiedades físicas asociadas a la dureza del grano en híbridos de maíz
(Universidad Tecnológica Nacional, Argentina, 2022-06-22)Se evaluó el efecto de distintos tratamientos de secado (natural, 50 y 70 °C) y manejo agronómico (sin y con re-fertilización en pre-floración) sobre la dureza endospérmica en cuatro híbridos de maíz (AW 190, NK 940, Cóndor ... -
Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
(Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
Secuencias de cultivos anuales para forraje y pastura perenne en suelo agrícola degradado
(Ediciones INTA, 2022-08)La intensificación de los sistemas ganaderos a través de la incorporación de los cultivos anuales permite potenciar a las pasturas perennes. El objetivo del trabajo fue evaluar la producción forrajera, contenido de proteína ... -
Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
(Elsevier, 2022-08)In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ... -
Sistemas socioeconómicos : círculos de información en función del tiempo
(Instituto Argentino para el Desarrollo Económico - IADE, 2022-04)La teoría económica competitiva provee la estructura del mercado ideal. El paradigma neoclásico plantea el supuesto de la información disponible completa y gratuita. No obstante, abundante evidencia empírica demuestra que ... -
Organic agriculture in Argentina’s Pampas. A case study on Pampa Orgánica Norte farmers
(Cambridge University Press, 2022-02)Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative ... -
Should farmers follow the recommendations of market advisory services? A hierarchical bayesian approach to estimation of expected performance
(Wiley, 2010-04-07)ABayesian hierarchical approach is employed to estimate individual expected performance of agricultural market advisory services. Skeptical beliefs based on market efficiency are incorporated as prior information. For a ... -
Detection of ovine antibody to Brucella ovis by Indirect Enzyme Immunoassay
(Taylor & Francis Group, 2007)Because some batch-to-batch variation in the preparation of rough lipopolysaccharide (RLPS) from Brucella ovis has been experienced, several protocols were tested to establish the most reliable method for detection of ... -
Expressing the sunflower transcription factor HaHB11 in maize improves waterlogging and defoliation tolerance
(Oxford University Press, 2022-05)The sunflower (Helianthus annuus) transcription factor HaHB11 (H. annuus Homeobox 11) belongs to the homeodomain-leucine zipper family and confers improved yield to maize (Zea mays) hybrids (HiII × B73) and lines. Here we ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
Environment affects starch composition and kernel hardness in temperate maize
(Wiley, 2022-03)BACKGROUND: Protein percentage and kernel weight affect the endosperm hardness of maize grains. However, changes in starch composition could also modify kernel hardness, which is often predicted through milling ratio. The ... -
Detecting sources of resistance to multiple diseases in Argentine maize (Zea mays L.) germplasm
(Springer Nature, 2022-04)Maize (Zea mays L.), an important cereal for human and animal nutrition, is usually affected by multiple co-occurring pathogens that reduce production. Argentina is the fourth maize producer worldwide, with common rust ... -
Cane molasses and oligofructose in the diet of laying hens improves the mineral content of eggs and meat
