A brassinosteroid functional analogue increases soybean drought resilience
(Nature Research, 2022-07-04)Drought severely affects soybean productivity, challenging breeding/management strategies to increase crop resilience. Hormone-based biostimulants like brassinosteroids (BRs) modulate growth/defence trade-off, mitigating ... -
A multi-resolution approach to national-scale cultivated area estimation of soybean
(2017-06)Satellite remote sensing data can provide timely, accurate, and objective information on cultivated area by crop type and, in turn, facilitate accurate estimates of crop production. Here, we present a generic multi-resolution ... -
Adoption of herbicide resistant soybean in Argentina: an economic analysis
(Springer, 2003)Soybean cultivation was introduced in the Pampean region of Argentina in the 1970s, and has been characterized by an incredible rate of adoption and growth. In 1970–71, soybean production amounted to 59,000 tons, with a ... -
Agrohydrological analysis of groundwater recharge and land use changes in the Pampas of Argentina
(Elsevier, 2019-03)This paper studies the changes of groundwater, climate and land use in the Pampas of Argentina. These changes offer opportunities and threats. Lowering groundwater without irrigation causes drought and successive crop and ... -
An In Vitro Method for Studying the Three-Way Interaction between Soybean, Rhizophagus irregularis and the Soil-Borne Pathogen Fusarium virguliforme
(2017-06)In this work, we described an in vitro system adequate for investigating the pathosystem soybean/arbuscular mycorrhizal fungi (AMF)/Fusarium virguliforme. Pre-mycorrhized plantlets with Rhizophagus irregularis were infected ... -
An inoculant Bradyrhizobium strain with increased motility improves yield of soybean crops
(Asociación Argentina de Microbiología, 2021-09-15)Soybean production is very important in Argentina, where more than 20 million hectares are sowed annually with this crop. Since soybean plants possess a very high N-demand, it is crucial that this agricultural activity is ... -
Análisis comparativo de limitantes del proceso de innovación en sistemas agrícolas familiares de La Pampa, San Luis y Chaco
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2015-11-05)El objetivo de este trabajo es analizar de manera comparativa los condicionantes (o limitantes) de la adopción de Tecnologías Críticas Comunes (TCC) en maíz y soja en tres provincias del país: La Pampa, San Luis y Chaco ... -
Análisis de la expresión diferencial de genes durante el desarrollo del síndrome de muerte súbita. Interacción soja (Glycine Max (L.)Mer / Fusarium Virguliforme)
(Universidad Internacional de Andalucía, 2010)La soja (Glycine max (L.) Merr.), es en la actualidad el cultivo más importante de Argentina, no solo por la magnitud del área que ocupa, sino, fundamentalmente, porque la mayor parte de su producción se destina a la ... -
Un análogo de brasinoesteroide confiere tolerancia a la sequía en soja
(REDBIO, 2021-06)Los bioestimulantes a base de fitohormonas son una alternativa práctica para mitigar los efectos de la sequía en el cultivos claves como la soja. Los brasinoesteroides (BRs) promueven el crecimiento y la respuesta ... -
Aporte de la fijación biológica de nitrógeno a la emisión de N2O desde el suelo con cultivo de soja = Contribution of biological nitrogen fixation to N2O emission from soil under soybean
(Asociación Argentina de la Ciencia del Suelo, 2015)El óxido nitroso (N2O) es el principal gas de efecto invernadero emitido desde el sector agrícola y su producción biológica en los suelos se genera por dos vías, la nitrificación y la desnitrificación. Recientemente el ... -
Aportes a la producción sustentable de soja mediante el mejoramiento genético de los rizobios
(Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2022-07-14)La soja es el cultivo que consume más inoculantes a nivel global. Estos inoculantes están basados casi en su totalidad en cepas relacionadas de las especies Bradyrhizobium japonicum y Bradyrhizobium diazoefficiens. ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina
(Springer, 2014-10)The increasing proportion of agricultural lands worldwide makes it necessary to intensify the research concerning the carbon exchange at agricultural sites. In order to determine the Net Ecosystem Exchange (NEE) in an ... -
Bean yellow mosaic virus in soybean from Argentina
(Wiley, 2014-05)An association of Bean yellow mosaic virus (BYMV), (genus Potyvirus), with yellow mosaic leaf symptoms on soybean in Argentina was determined by enzyme-linked immunosorbent assay, a result confirmed by transmission electron ... -
Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil
(Frontiers Media, 2021-08-11)The aim of this study was to explore relationships between protein, oil, and seed weight with seed nutraceutical composition, focused on total isoflavone (TI) and total tocopherol (TT) contents across genotypic and ... -
