(MDPI, 2023-05)The characterization and evaluation of water quality in the Valle Bonaerense del Río Colorado (VBRC), Buenos Aires, Argentina, is necessary, given the immense importance of this region for sustaining the population livelihoods ... -
Crop-wild sunflower hybridization can mediate weediness throughout growth-stress tolerance trade-offs
(2017-11)Agricultural weeds are plants well-adapted to agricultural environments interfering directly and indirectly with crop production and causing important economic losses worldwide. Crop-wild hybridization is one of the main ... -
Curvas de crecimiento de forrajeras templadas irrigadas
(Asociación Latinoamericana de Producción Animal, 2001)Con el objetivo de construir y comparar las curvas de distribución estacional de forraje de 15 gramíneas y leguminosas se realizaron cuatro ensayos entre 1996 y 1999. Cada uno constó de dos repeticiones compuestas cada una ... -
Desinfección del suelo en el cultivo de frutilla en el sudoeste bonaerense = Soil disinfection in strawberry production in the southwest of Buenos Aires province
(Asociación Argentina de Horticultura (ASAHo), 2024-04)El Valle Bonaerense del Río Colorado (VBRC) ha demostrado ser agroclimáticamente apto para la producción de frutilla (Fragaria x ananassa Duch.). Sin embargo, hongos patógenos del suelo que afectan a este cultivo fueron ... -
Development and validation of a simulation model for hairy vetch (Vicia villosa Roth) self-regeneration under different crop rotations
(Elsevier, 2019-04)Hairy vetch (HV, Vicia villosa Roth) is a winter annual legume cultivated for pasture grazing, in crop rotations with cereal crops under semi-arid conditions. The inclusion of HV increases soil nitrogen, thus contributing ... -
Diversity of Auchenorrhyncha (Hemiptera: Cicadellidae: Delphacidae) associated with Vicia villosa in southern Buenos Aires province, Argentina
(2014-06)Among the Hemiptera, the Auchenorrhyncha are well known owing to their phytosanitary relevance since the group includes pathogen vector species able to damage commercial crops. Vicia villosa Roth (Fabaceae) is a fodder ... -
Efecto de rotaciones agrícolas con cebolla sobre las propiedades químicas del suelo y producción de policultivo avena-vicia y resiembra natural de Vicia villosa Roth. en el sur de Buenos Aires
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)En el valle bonaerense del Río Colorado (VBRC), sur de Buenos Aires, Vicia villosa (Roth) se adapta como cultivo de cobertura (CC) por su elevada producción de biomasa en primavera.
