(Instituto de Economía y Sociología, INTA, 2002-05)Este trabajo forma parte del Proyecto Foncyt PICT 3524, “Economía de la Investigación Agrícola: Derrames de Conocimiento, Economías de Escala y de Diversidad en la Producción de Tecnología en Trigo y Soja”. Sus objetivos ... -
Response of determinate and indeterminate soybean cultivars to basal and topdressing N fertilization compared to sole inoculation with Bradyrhizobium
(Elsevier, 2016-08)Soybean (Glycine max (L.) Merrill) new cultivars have high N demands to sustain increasing grain yields. One may ask whether these cultivars would need basal and/or topdressing N application as perhaps symbiotic N2 fixation ... -
Response of soil microbial communities to different management practices in surface soils of a soybean agroecosystem in Argentina
(Elsevier, 2010-12-03)Argentina is the world’s third most important soybean producer; hence, there is an urgent need to preserve soil health by applying appropriate agricultural practices to maintain sustainable production in the upcoming years. ... -
Respuesta en el corto plazo de algunas propiedades físicas a la introducción de cultivos de cobertura = Short term effects of cover crops on some soil physical properties
(Asociación Argentina de la Ciencia del Suelo, 2016)Para evitar la degradación física del suelo se necesitan estrategias de gestión sostenibles. En este sentido, la intensificación en la secuencia de cultivos genera un uso más eficiente de los recursos ambientales, aumentando ... -
Respuestas fisiológicas de materiales de soja en simbiosis con micorrizas bajo estrés por sequía
(REDBIO, 2021-06)Encontrar estrategias para mitigar las pérdidas por sequía en plantas, resulta un desafío para la agricultura Una posibilidad es desarrollar tecnologías para aprovechar los beneficios de las simbiosis con los hongos ... -
Saline and osmotic stress differentially affects apoplastic and intracellular reactive oxygen species production, curling and death of root hair during Glycine max L.–Bradyrhizobium japonicum interaction
(Elsevier, 2011-12-08)In the present study, the production of apoplastic and intracellular reactive oxygen species (ROS) and deformations of young soybean root hairs inoculated with Bradyrhizobium japonicum strain USDA138 were analyzed under ... -
Servicios ecosistémicos: una mirada desde los intercultivos
(Universidad de Morón, 2022-04)Los servicios ecosistémicos se pueden definir como las condiciones y procesos a través de los cuales los ecosistemas y las especies que la conforman, mantienen y satisfacen al hombre. En este sentido, un manejo agrícola ... -
Soil microbial communities under different soybean cropping systems: Characterization of microbial population dynamics, soil microbial activity, microbial biomass, and fatty acid profiles
(Elsevier, 2008-12-05)This work analyzes the direct effect of soil management practices on soil microbial communities, which may affect soil productivity and sustainability. The experimental design consisted of two tillage treatments: reduced ... -
Soybean frogeye leaf spot [Cercospora sojina] : first weather-based prediction models developed from weather station and satellite data
(2015-06-30)In Argentina, soybean frogeye leaf spot occurs sporadically. However, particularly in the Pampas Region, the incidence and severity of this fungal disease have significantly increased in the last years. In the present ... -
Soybean in rotation with cereals attenuates nitrous oxide emissions as compared with soybean monoculture in the Pampas region
(Elsevier, 2021-11)Nitrous oxide (N-N2O) emissions in the agricultural sector represent ca. 25% of total N-N2O emissions on a global scale. In Argentina, information on agricultural emissions is scarce, and thus, N-N2O emissions are estimated ... -
Soybean oil biodiesel production in Argentina case study
(Etaflorence, 2014-06)Soybean production is immersed within a productive system that cannot be analyzed on its own. A number of political and market factors, both nationally and internationally, explain the development and growth of soybean ... -
Soybean pod and grain isoflavones accumulation during the filling period in field conditions
(Ediciones INTA, 2021-12)The objective of this work was to determine the isoflavones accumulation in soybean pods and grains during the filling period in field conditions. Pods of the same phenological stage (marked in R5, i.e. beginning of grain ... -
Soybean responseto initial stage of Fusarium virguliforme infection
(BioRxiv, 2022-03-07)Fusarium virguliforme causes the Sudden Death Syndrome, an important disease in soybean crops. In this work, we investigated the defensive response mechanisms in soybean root, at cell wall level, during F. virguliforme ... -
Soybean seed growth dynamics exposed to heat and water stress during the filling period under field conditions
(Wiley, 2021-05-27)Soybean production can be affected by heat (HS) and water stress (WS). However, studies on effects of stresses combination under field conditions are still scarce. The objective of this study was to evaluate the impact of ... -
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ... -
The benefits of foliar inoculation with Azospirillum brasilense in soybean are explained by an auxin signaling model
(2018-09)Azospirillum sp. is one of the most studied genera of plant growth-promoting rhizobacteria (PGPR). The ability of Azospirillum sp. to promote plant growth has been associated with its ability to produce several phytohormones, ... -
