Jatropha curcas L. and J. macrocarpa Griseb: seed morphology, viability, dormancy, germination and growth of seedlings
(Scientific Research, 2018-08)To achieve a good production of a crop, it is essential to know the ability of the species to successfully complete two critical stages in the life cycle such as germination and seedling establishment. In this paper we ... -
Kernel hardness-related traits in response to heat stress during the grain-filling period of maize crops
(Crop Science Society of America, 2019-02)Postflowering heat stress causes the arrest of kernel growth, increasing kernel protein concentration and the relative abundance of γ-zeins, two biochemical traits contributing to maize (Zea mays L.) hardness. The impact ... -
Livestock Grazing Impacts on Herbage and Shrub Dynamics in a Mediterranean Natural Park
(2013-03)Shrub encroachment can be explained by the abandonment of extensive livestock farming and changes to land use, and it is a common problem in the Mediterranean mountain pastures of Europe, with direct effects on biodiversity ... -

Modeling Rainwater Harvesting and Storage Dynamics of Rural Impoundments in Dry Chaco Rangelands
(MDPI, 2023-06)Transporting water to supply livestock is one of the great challenges of the drylands. Ranchers usually make impoundments, filled by runoff, to access freshwater for cattle supply in flat rangelands. The aim of this study ... -
Pathogenic diversity of Phytophthora sojae in the southeast of the Province of Buenos Aires
(Springer, 2020-06-08)Phytophthora sojae causes root and stem rot of soybeans. In Argentina, this pathogen has shown dramatic shifts in pathotype variability since its first discovery during the 1970s. The aim of this study was to report the ... -
Plant-soil feedback in the ‘real world’: how does fire fit into all of this?
(Springer, 2022-12-05)Aims: Plant–soil feedback (PSF) is an important mechanism controlling plant growth, vegetation dynamics, and longer-term and larger-scale patterns of plant community diversity. We know that feedback between plants and soil ... -
Plants vs. Streams: Their groundwater‐mediated competition at “El Morro”, a developing catchment in the dry plains of Argentina
(Wiley, 2021-04)Our understanding of how groundwater mediates evapotranspiration/streamflow partitioning is still fragmented and catchment studies under changing vegetation conditions can provide a useful frame for integration. We explored ... -
Potential technological use of reserves of Jatropha curcas and J. macrocarpa Griseb. seeds
(Scientific Research, 2019-08)J. curcas and J. macrocarpa are useful for restoring degraded areas and their seeds contain oils for biodiesel production. The aim of the work was to determine the reserve substances in the endosperm and the embryo of J. ... -
Productive performance of alternative land covers along aridity gradients: ecological, agronomic and economic perspectives
(2016-11)The replacement of natural vegetation by pastures and extensive crops is generally driven by economic incentives and supported by technology improvements and multiple subsidies. However, towards areas of increasing aridity ... -
Rainwater harvesting in Dry Chaco: Regional distribution and local water balance
(2015-12)Rainwater harvesting (RWH) has been essential for the establishment of human settlements in many dry regions of the world that lacked suitable surface or groundwater resources. A vast fraction of the South American Dry ... -
Relative soil water content as a factor for wind erodibility in soils with different texture and aggregation
(Elsevier, 2019-04)The soil water content is one of the main factors influencing the beginning of soil particle movement by the wind. Although, some authors studied the effect of soil water content on threshold wind velocity and have defined ... -
Remoción de carbono orgánico, nitrógeno y fósforo por erosión eólica en un Haplustol éntico
(Asociación Argentina de la Ciencia del Suelo, 2022-08)Conocer la dinámica de pérdida de nutrientes debido a la severidad de las tormentas eólicas contribuiría a entender este proceso y a predecir el efecto de eventos extremos debido al calentamiento global. Es por ello que ... -
Rendimiento de grano y eficiencia en el uso del agua en maíz bajo riego complementario con agua salina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-12)En San Luis, Argentina, el cultivo de maíz es relevante con un rendimiento medio de grano de 1.600 kg ha-1 inferior al potencial con riego complementario (14.000 kg ha-1). No siempre se dispone de agua de calidad para ... -
