How does the neighborhood of annual or perennial species affect the first one hundred days of the establishment of grasses?
(Facultad de Agronomía e Ingeniería Forestal, Universidad Católica de Chile, 2024-03)Pastures that include annual and perennial grasses can play a strategic role in increasing the sustainability of temperate livestock systems. However, the impacts of the competition between annual and perennial genetically ... -
Escurrimiento, producción de sedimentos y elementos asociados en distintos ambientes de la Pampa Ondulada
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Ríos, 2022-10)En la Pampa Ondulada, las distintas posiciones del paisaje presentan suelo con diferentes propiedades y una disímil fisiografía. El coeficiente de escurrimiento (CE), la producción de sedimentos (SE) y de los elementos ... -
Metal cation concentrations improve understanding of controls on soil organic carbon across a precipitation by vegetation gradient in the Patagonian Andes
(Elsevier, 2023-12)Tephra-derived soils retain more organic carbon (C) than soils formed from any other parent material, but this C may be sensitive to changes in climate and land use. Here we evaluate the effects of precipitation, temperature, ... -
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 ... -
Human-nature interaction approached from a bibliometric analysis of Malthus and Boserup
(Ediciones INTA, 2024-05)The theoretical framework of Complex Adaptive Systems allows modeling human-environment interactions that are constantly evolving and have implications for sustainability. The aim of this paper is to identify which approach, ... -
El mejoramiento genético de cebadilla criolla (Bromus catharticus Vahl) en Argentina : síntesis de los logros y avances = The genetic improvement of prairie grass (Bromus catharticus Vahl) in Argentina : synthesis of achievements and advances
(Sociedad Argentina de Genética, 2023-07)La cebadilla criolla (Bromus catharticus Vahl) es la gramínea forrajera nativa anual/bianual de clima templado de mayor importancia y difusión en la Argentina. Varios autores han estudiado la variabilidad fenotípica en ... -
Timing is everything: how planting period shapes nutritional quality, mycobiota characteristics, and mycotoxin contamination in maize (Zea mays) grains
(Springer Nature, 2024-01)Maize (Zea mays L.) is crucial in global grain markets and food/feed production. Fungal contamination in ears can adversely affect crop yield and diminish the nutritional value of grains. Moreover, many of the main pathogens ... -
Enhancement of late-sown maize production with immobilized bacteria in chitosan/starch beads in different crop management conditions
(Springer Nature, 2024-01)Immobilization of plant growth-promoting rhizobacteria in biodegradable polymeric matrices has the potential to improve crop yield and overcome rhizosphere challenges. Previously, we demonstrated that beads prepared from ... -
