Modeling forest site productivity using climate data and topographic imagery in Pinus elliottii plantations of central Argentina
(Springer Science, 2020-10)Key message: To be useful for silvicultural and forest management practices, the models of Site Index (SI) should be based on accessible predictor variables. In this study, we used spatially explicit data obtained from ... -
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
(Springer Nature, 2020-10-07)Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ... -
Microsatellite genotyping reveals extensive genetic diversity in bovine Neospora caninum from the humid Pampa region in Argentina
(Springer Verlag, 2020-10-15)Neospora caninum is an apicomplexan protozoan and a major cause of abortion in cattle worldwide. In the Argentinian Humid Pampa, bovine neosporosis causes severe economic losses. Despite this, information on the genetic ... -
Monensin occurrence in surface water and its impact on aquatic biota in a stream of the southeast Pampas, Argentina
(Springer Science, 2020-10-16)Monensin is an ionophore antibiotic used as a feed additive and growth promoter in cattle production worldwide. The occurrence of monensin in aquatic surficial ecosystems is of concern due to its possible detrimental effects ... -
The scale dependency of spatial crop species diversity and its relation to temporal diversity
(National Academy of Sciences, 2020-10-20)Increasing crop species diversity can enhance agricultural sustainability, but the scale dependency of the processes that shape diversity and of the effects of diversity on agroecosystems is insufficiently understood. We ... -
Analysis of Genetic Variability in the Argentine Polo Horse With a Panel of Microsatellite Markers
(Elsevier, 2020-11)Argentine Polo (AP) is a young horse breed with a fast expansion because of an open registry policy and the application of assisted reproduction technologies. In the last years, AP showed a remarkable progress associated ... -
Upregulation of interferon-alpha gene in bovine embryos produced in vitro in response to experimental infection with noncytophatic bovine-viral-diarrhea virus
(Springer, 2020-11)In-vitro fertilization is a routine livestock-breeding technique widely used around the world. Several studies have reported the interaction of bovine viral-diarrhea virus (BVDV) with gametes and in-vitro-produced (IVP) ... -
Frequency of bovine viral diarrhea virus (BVDV) in Argentinean bovine herds and comparison of diagnostic tests for BVDV detection in bovine serum samples: a preliminary study
(Elsevier, 2020-11)Bovine viral diarrhea (BVD) is a major worldwide disease with negative economic impact on cattle production. Successful control programs of BVD require the identification and culling of persistently infected (PI) animals ... -
Variation in reproductive frost susceptibility of wheat cultivars is not associated with variation in glume and lemma thickness
(Elsevier, 2020-11-05)The thickness of wheat (Triticum aestivum L.) glumes and lemmas (TGL) influences their thermal insulation properties, which in turn, may influence reproductive frost susceptibility. The objectives of this study were to (i) ... -
Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols
(Taylor and Francis, 2020-11-12)Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized to improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, ... -
Cartografías y caracterización de las experiencias agroecológicas en el Cinturón Hortícola del Partido de General Pueyrredon
(Asociación Argentina de Horticultura, 2020-11-25)En consonancia con los cambios en el modelo productivo a nivel regional y con las tensiones y controversias que atraviesan la actividad hortícola en las áreas de interfaz urbano-rural de Mar del Plata (Partido de General ... -
Secuencia de cultivos con predominio de soja: efecto sobre indicadores de calidad física del suelo.
(Asociación Argentina de la Ciencia del Suelo, 2020-12)El aumento en la frecuencia del cultivo de soja y de su monocultivo puede provocar disminuciones en la materia orgánica del suelo (MO) y afectar sus propiedades físicas. Sin embargo, prácticas de manejo como la fertilización, ... -
Lotus tenuis (Waldst. et Kit), estudio para un manejo con múltiples propósitos
(Ediciones INTA, 2020-12)El uso de cultivos con múltiples propósitos es una opción que permite obtener de un mismo sistema de producción diferentes servicios ecosistémicos. El objetivo del presente trabajo fue combinar fechas de corte en un cultivo ... -
Management effects on glyphosate and AMPA concentrations in the PM10 emitted by soils of the central semi-arid region of Argentina
(Elsevier, 2020-12)In soils of semi-arid regions, different amounts of glyphosate are applied, and this substance tends to be absorbed on the topsoil exposed to erosion. The objective of this study was to analyze the effects of land management ... -
Tolerance of Pedunculate oak (Quercus robur) saplings to herbicides
(Ediciones INTA, 2020-12)Spraying herbicides to reduce weed competition is a usual practice in agricultural regions. However, tree tending under agroforestry or forest plantations is hampered by the extensive use of these pesticides. Here, we ... -
Storing soybeans (Glycine max) in silo bags: economic outcomes and grain loss risk
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12-01)Silo bags have the potential to increase grain marketing efficiency and to give farmers additional bargaining power. However, silo bags are prone to tearing that can cause grain losses. This article assesses the economic ... -
