Aplicación de fósforo en secuencias agrícolas en siembra directa en hapludoles énticos = Phosphorus fertilization in crop sequences in entic hapludolls
(Asociación Argentina de la Ciencia del Suelo, 2016)Los contenidos de fósforo (P) extractable de la mayoría de los suelos de la región pampeana disminuyeron al intensificarse su extracción con cultivos y pasturas. Son frecuentes los sitios con limitaciones en P que requieren ... -
Climate impacts on crop yields in Central Argentina. Adaptation strategies
(2018-02)The Pampas is among the major agricultural regions in the world; a large proportion of Argentina crop production is originated in this region. The exportation of grain and oil crop represents more than 40% of the total ... -
Comercialización de soja en la últimas dos décadas : mercado disponible vs. mercado de futuros
(2015-12)El agente decisor sobre la producción agropecuaria debe identificar los momentos de precios elevados a fin de obtener un buen precio de venta de su producción. Sin embargo, el agente tomador de decisión posee limitaciones ... -
Contrasting effects of soil type and use of cover crops on nitrogen and phosphorus leaching in agricultural systems of the Argentinean Pampas
(Elsevier, 2024-01)Agricultural systems of the Argentinean Pampas generally use rotations of summer crops under no-tillage and apply fertilization at rates that do not compensate nutrient exports with grain harvest, resulting in negative ... -
Costos ambientales y eficiencia productiva en la producción agraria del partido de Pergamino
(2013)Mediante un modelo de frontera de producción estocástica se analizó el nivel de eficiencia técnica para la producción de soja, maíz y trigo en empresas agropecuarias del partido de Pergamino, Buenos Aires, Argentina. El ... -
Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
(Springer Nature, 2022)Cropping diversification with cover crop mixtures combined with low N fertilization represents an ecological alternative that may promote sustainability. Our objective was to evaluate changes on soil organic fractions and ... -
Efectos de diferentes estrategias de fertilización sobre los rendimientos, el balance de nutrientes y su disponibilidad en los suelos en el largo plazo
(IPNI, 2015-09)A nivel productivo, las deficiencias de nitrógeno (N), fósforo (P) y azufre (S) no ocurren de manera aislada sino que se combinan de diversas maneras, por lo que es necesario evaluar integralmente la respuesta a la ... -
Evaluación del tizón foliar y la mancha púrpura en semilla de soja en Argentina = Evaluation of leaf blight and purple seed stain in soybean in Argentina
(Universidad de Costa Rica, 2021-05)El tizón foliar por Cercospora y la mancha púrpura de la semilla son enfermedades endémicas de la soja en Argentina. Objetivo. Evaluar la prevalencia, la incidencia y la severidad del tizón foliar por Cercospora y de la ... -
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 ... -
Introduction of cover crops in a maize–soybean rotation of the Humid Pampas: Effect on nitrogen and water dynamics
(Elsevier, 2012-03)The agricultural system of the Humid Pampas consists of continuous cropping of soybean and maize under no tillage. This system may loose nitrogen (N) through leaching during the early and final stages of summer crops and ... -
Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
No Common Candidate Genes for Resistance to Fusarium graminearum, F. proliferatum, F. sporotrichioides, and F. subglutanins in Soybean (Glycine max L.) Accessions from Maturity Groups 0 and I: Findings from Genome-Wide Association Mapping
(The American Phytopathological Society, 2024-04)Seedling diseases and root rot, caused by species of Fusarium, can limit soybean (Glycine max L.) production in the United States. Currently, there are few commercially available cultivars resistant to Fusarium. This study ... -
On-farm soybean genetic progress and yield stability during the early 21st century: A case study of a commercial breeding program in Argentina and Brazil
(Elsevier, 2024-03)CONTEXT: Most studies assessing the genetic progress in soybean have traditionally focused on retrospectives approaches, where commercial genotypes released over an extended period are tested in a limited number of ... -
OSTRICH-CROPGRO multi-objective optimization methodology for calibration of the growing dynamics of a second-generation transgenic soybean tolerant to high temperatures and dry growing conditions
(Elsevier, 2023-02)Current estimates show that the impact of climate change on agriculture will result in yield losses in major crops of 8–43%, mainly due to a combination of drought and heat. Second-generation transgenic crops are expected ... -
Pathogenic diversity of soybean rust in Argentina, Brazil, and Paraguay
(Springer, 2013-01)Phakopsora pachyrhizi, the cause of soybean rust, is an economically important pathogen of soybean in South America. Understanding the pathogenicity of indigenous fungal populations is useful for identifying resistant plant ... -
