Water productivity in soybean following a cover crop in a humid environment
(Elsevier, 2020-02-05)We evaluated the influence of the termination dates of a winter cover crop on (i) soil water availability during soybean (Glycine max L. (Merr)) growing season, (ii) soybean evapotranspiration (ET) and iii) water productivity ... -
Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina
(Elsevier, 2021-01-14)The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ... -
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) ... -
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 ... -
Combined moxidectin-levamisole treatment against multidrug-resistant gastrointestinal nematodes: A four-year efficacy monitoring in lambs
(Elsevier, 2021-01-26)Nematicide combinations may be a valid strategy to achieve effective nematode control in the presence of drug resistance. The goal of the current trial was to evaluate the pharmaco-parasitological performance of the ... -
Effect of the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments
(Elsevier, 2021-01-19)In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ... -
Effect of bovine viral diarrhea virus on subsequent infectivity of bovine gammaherpesvirus 4 in endometrial cells in primary culture: An in vitro model of viral co-infection
(Elsevier, 2021-02-15)Bovine viral diarrhea virus (BVDV) and bovine gammaherpesvirus 4 (BoHV-4) infect the uterus of cattle, being responsible for huge economic losses. Most of the pathogenesis of BoHV-4 in the bovine reproductive tract has ... -
First evidence of glyphosate and aminomethylphosphonic acid (AMPA) in the respirable dust (PM10) emitted from unpaved rural roads of Argentina
(Elsevier, 2021-02-04)The aim of this work was to compare the concentration of glyphosate and AMPA in the PM10 and the actual PM10 emission from agricultural soils and unpaved roads, located inside and outside farm fields. To determine the ... -
Accurate and fast identification of Campylobacter fetus in bulls by real-time PCR targeting a 16S rRNA gene sequence
(Elsevier, 2020-12-24)Campylobacter fetus is an important animal pathogen that causes infectious infertility, embryonic mortality and abortions in cattle and sheep flocks. There are two recognized subspecies related with reproductive disorders ... -
Bioformulación de Trichoderma harzianum en sustrato sólido y efectos de su aplicación sobre plantas de pimiento
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-07-11)Para la implementación de biofertilizantes se pretende que su formulación sea económica, de fácil aplicación y que garantice la eficacia del inóculo. Nuestro objetivo fue seleccionar un sustrato para vehiculizar Trichoderma ... -
Uso del índice de verdor para determinar la dosis optima económica de nitrógeno en maíz
(Asociación Argentina de la Ciencia del Suelo, 2019-06)En regiones con excesos hídricos al comienzo de la estación de crecimiento, la aplicación de nitrógeno (N) en estadíos tempranos del maíz no es la mejor estrategia para maximizar la eficiencia de uso de dicho nutriente. ... -
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 ... -
Innate and humoral immune parameters at delivery in colostrum and calves from heifers experimentally infected with Neospora caninum
(Elsevier, 2021-02-02)Neospora caninum is a leading cause of abortion in cattle worldwide. The study of the immune response against N. caninum is critical to understand its epidemiology, pathogenesis, diagnosis and, ultimately, in preventing ... -
Critical period for seed number determination in soybean as determined by crop growth rate, duration, and dry matter accumulation
(Elsevier, 2020-12-13)Seed number (SN) is positively associated with aboveground dry matter (ADM) accumulation in most crop species. In soybean, there are discrepancies among studies relative to the start and end of the critical period for seed ... -
Forage yield gap analysis for tall fescue pastures in Argentina: A modelling approach
(Wiley, 2020-12-07)A large gap between actual and potential herbage production of tall fescue is a major limitation for livestock production systems in Argentina. The objectives of this work were to (a) calibrate and test the ability of a ... -
Determining Mehlich-3 and DTPA extractable soil zinc optimum economic threshold for maize
(Wiley, 2020-09-16)Maize (Zea mays L.) is one of the most susceptible crops to zinc (Zn) deficiency. However, in much of the world, soil Zn tests are poorly calibrated, and thus determining a critical soil test, level for Zn is challenging. ... -
Prognosis and diagnosis of sulfur status in maize by plant analysis
(Elsevier, 2019-05)The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ... -
