Should farmers follow the recommendations of market advisory services? A hierarchical bayesian approach to estimation of expected performance
(Wiley, 2010-04-07)ABayesian hierarchical approach is employed to estimate individual expected performance of agricultural market advisory services. Skeptical beliefs based on market efficiency are incorporated as prior information. For a ... -
Sistemas socioeconómicos : círculos de información en función del tiempo
(Instituto Argentino para el Desarrollo Económico - IADE, 2022-04)La teoría económica competitiva provee la estructura del mercado ideal. El paradigma neoclásico plantea el supuesto de la información disponible completa y gratuita. No obstante, abundante evidencia empírica demuestra que ... -
Soil microbial functionality in response to the inclusion of cover crop mixtures in agricultural systems
(2016)Agricultural systems where monoculture prevails are characterized by fertility losses and reduced contribution to ecosystem services. Including cover crops (CC) as part of an agricultural system is a promising choice in ... -
Soil porosity characteristics and water movement under zero tillage in silty soils in Argentinian Pampas
(Elsevier, 2006-05)The objective of this study was to identify pore characteristics (quantity, distribution, stability and orientation of pores) that condition water dynamics under continuous zero tillage (ZT) on silty soils of the Argentinian ... -
Source-sink relations and kernel weight in maize inbred lines and hybrids : responses to contrasting nitrogen supply levels
(Elsevier, 2019-01)Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is ... -
Standardization of Immunobiological Assay for Determines Identity of Junin virus Vaccine, Candid#1
(2017-04)The quality control tests of the Candid#1 vaccine required for internal release needs the use of rabbit immune serum (RIS). It is a biological reagent produced in INEVH and it must be qualied to ensure its proper use. ... -
Structure of the novel monomeric glyoxalase I from Zea mays
(International Union of Crystallography, 2015-10)The glyoxalase system is ubiquitous among all forms of life owing to its central role in relieving the cell from the accumulation of methylglyoxal, a toxic metabolic byproduct. In higher plants, this system is upregulated ... -
Sulfur fertilization technology in the Argentine Pampas region : a review
(Facultad de Agronomía, Universidad de Buenos Aires, 2012-05)Sulfur (S) deficiencies in grain crops have become increasingly frequent worldwide, including the Argentine Pampas region, located in South America. The objective of this work is to review recent research literature regarding ... -
The herbage productivity of tall fescue in the Pampas region of Argentina is correlated to its ecological niche
(Wiley, 2016-09)Since its introduction in the 1950s, tall fescue has spread throughout the Pampas region of Argentina to become naturalized in much of this region. Its annual forage mass productivity shows significant differences among ... -
The physiology and genetics behind fruiting efficiency, a promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-03)The fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination (the ... -
The Use of Detached Leaf Inoculation for Selecting Cercospora kikuchii Resistance in Soybean Genotypes
(The American Phytopathological Society (APS), 2021-11)Cercospora leaf blight (CLB) causes extensive losses in soybean production in worldwide, including major soybean-producing countries such as Argentina. Cercospora kikuchii, C. cf. sigesbeckiae, C. cf. flagellaris, and C. ... -
Timing is everything: how planting period shapes nutritional quality, mycobiota characteristics, and mycotoxin contamination in maize (Zea mays) grains
(Springer Nature, 2024-01)Maize (Zea mays L.) is crucial in global grain markets and food/feed production. Fungal contamination in ears can adversely affect crop yield and diminish the nutritional value of grains. Moreover, many of the main pathogens ... -
Toasting time and cooking formulation affect browning reaction products development in corn flakes
(2017-03)During toasting, the last stage of corn flake production, Maillard reaction takes place, favored by the high temperature and low water content. The cooking formulation ingredients influence color and flavor of the final ... -
Transcriptional and metabolic changes associated to the infection by Fusarium verticillioides in maize inbreds with contrasting ear rot resistance
(2013)Fusarium verticillioides causes ear rot and grain mycotoxins in maize (Zea mays L.), which are harmful to human and animal health. Breeding and growing less susceptible plant genotypes is one alternative to reduce these ... -
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
(Springer Nature, 2022-02)Maize is one of the most important cereals for both human and animal nutrition, and diseases that affect the crop pose a major threat to global food security. Breeders are racing against time to develop genotypes resistant ... -
Updated guidelines for gene nomenclature in wheat
(Springer Nature, 2023-03)The last decade has seen a proliferation in genomic resources for wheat, including reference- and pan-genome assemblies with gene annotations, which provide new opportunities to detect, characterise, and describe genes ... -
Variabilidad, tendencia y eventos extremos en los rendimientos agrícolas a nivel de partidos en la Provincia de Buenos Aires
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-06-09)Climate variability is the main determinant of fluctuations in the productive and economic results of agriculture. Due to Climate Change, extreme events are expected to occur with greater frequency and intensity in the ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
(2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
