Carbono orgánico del suelo bajo sistemas de cultivo contrastantes y su relación con la capacidad de proveer nitrógeno
(2017)Los contenidos de carbono (C) orgánico total (COT) y particulado (COP) del suelo disminuyen con los años bajo agricultura y su variación afecta muchos procesos edáficos que determinan la productividad (e.g. la provisión ... -
Changes in soil biological properties in different management and tyllage systems in petrocalcic argiudoll
(Elsevier, 2020-12)We analyzed the effect of different tillage systems on soils under different land-use histories, on biological properties of soil during one year. The experiment was carried out at a Petrocalcic Argiudoll of Tres Arroyos ... -
Comparison of Gonadotropin-Releasing Hormone versus Estrogen-Based Fixed-Time Artificial Insemination Protocols in Grazing Bos taurus Suckled Beef Cows
(MDPI, 2023-09)Fixed-timed artificial insemination (FTAI) protocols for beef cattle in South America are primarily based on estradiol esters and intravaginal progesterone-releasing devices (IVPD). The objective of this study was to ... -
Comparison of premix glyphosate and 2,4-D formulation and direct tank mixture for control of Conyza canadensis and Epilobium ciliatum
(Elsevier, 2021-07)Premix or tank mix of glyphosate and 2,4-D are a good alternative to control glyphosate-resistant and -tolerant weeds; however, the combination of herbicides may increase the environmental impacts, since mixtures often ... -
Comparison of Sensitivity to Glyphosate of Euphorbia davidii Populations = Comparação da Sensibilidade ao Glyphosate de Populações de Euphorbia davidii
(2018)Euphorbia davidii (Euphorbiaceae) is a summer annual weed present in the Province of Buenos Aires, Argentina. The aim of this study was to compare the sensitivity to glyphosate of different populations of Euphorbia davidii. ... -
Constitutive overexpression of EPSPS by gene duplication is involved in glyphosate resistance in Salsola tragus
(Wiley, 2022-11)Background: Glyphosate-resistant Salsola tragus accessions have been identified in the USA and Argentina; however, the mechanisms of glyphosate resistance have not been elucidated. The goal of this study was to determine ... -
Contribution of tillers to maize yield stability at low plant density
(Wiley, 2022-08)One of the main challenges of using low plant densities in restrictive and variable environments is to maximize the use of resources in better-than-expected years. The adoption of prolific genotypes has addressed part of ... -
Convergent Adaptation of Multiple Herbicide Resistance to Auxin Mimics and ALS- and EPSPS-Inhibitors in Brassica rapa from North and South America
(MDPI, 2023-05)Herbicide-resistant weeds have been identified and recorded on every continent where croplands are available. Despite the diversity of weed communities, it is of interest how selection has led to the same consequences in ... -
Cultivable soil fungi community response to agricultural management and tillage system on temperate soil
(Elsevier, 2021-02)In agricultural soils, fungi constitute most of the total microbial biomass in the environment contributing with more than 50% of the soil biomass. The fungi should be considered as a link in the production not only by ... -
Cultivos de cobertura para maíz en el centro-sur bonaerense
(IPNI, 2017-12)Durante las últimas campañas, los cultivos de cobertura (CC) han cumplido un rol estratégico cuando la rotación no es suficiente para alcanzar un nivel de cobertura adecuado. Este trabajo evaluó los efectos del momento de ... -
Detection of recombinant human lactoferrin and lysozyme produced in a bitransgenic cow
(2017-03)Lactoferrin and lysozyme are 2 glycoproteins with great antimicrobial activity, being part of the nonspecific defensive system of human milk, though their use in commercial products is difficult because human milk is ... -
Developing a glyphosate-bioremediation strategy using plants and actinobacteria: potential improvement of a riparian environment
(Elsevier, 2022-12)Glyphosate (Gly) and its principal degradation product, the aminomethylphosphonic acid (AMPA) were found in soils from a riparian environment in Argentina. Sixty-five actinobacteria were isolated from these soils, rhizosphere, ... -
Developmental environment influences activity levels in a montane rodent, Phyllotis xanthopygus
(Elsevier, 2020-10)Ambient temperature and thermal variability play a crucial role in diverse aspects of organisms’ biology. In the current context of climate change, it is critical to understand how temperature impacts traits that could ... -
Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
(MDPI, 2018-11)The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ... -
Edaphic forms of phosphorus in no-tillage cropping sequences in the Argentine southern central Pampas
(2018-08)Agriculture significantly affects phosphorus (P) availability, thereby modifying P equilibrium. The objective of this study was to evaluate the effect of different crop sequences on the dynamics of soil P forms under no ... -
