Risk factors associated with the presence of aflatoxin M1 in raw bulk milk from Argentina
(2016-06)The objectives of this study were to assess aflatoxin M1 (AFM1) contamination in bulk tank milk, and to further identify the risk factors associated with the presence of AFM1 in raw milk in Argentina. The presence of AFM1 ... -
Aguadas para ganadería bovina en los bajos submeridionales y áreas de influencia
(2017)En el norte de la provincia de Santa Fe, especialmente en la Cuña Boscosa, Bajos Submeridionales y Domo Occidental, se encuentran más de tres millones de cabezas de ganado vacuno, donde uno de los principales condicionantes ... -
High pasture allowance does not improve animal performancein supplemented dairy cows grazing alfalfa during autumn–winter
(2015)The aim of this study was to assess the effect of three alfalfa pasture herbage allowances on milk yield and composition during autumn–winter grazing season on early autumn calving dairy cows. Eighteen multiparous Holstein ... -
Mitigación del estrés calórico durante el preparto en vacas lecheras
(2016)Se utilizaron 30 vacas en preparto que se alojaron en un corral seco con acceso a sombra artifi cial durante el verano. Las vacas fueron distribuidas en dos grupos: sin refrescado (TS) y con refrescado (TR) en el sector ... -
Seasonal dynamics, geographical range size, hosts, genetic diversity and phylogeography of Amblyomma sculptum in Argentina
(2018-04)The aim of this work was to generate knowledge on ecological aspects of Amblyomma sculptum in Argentina, such as seasonal dynamics, geographical range size, hosts, genetic diversity and phylogeography. Adult and immature ... -
Miel de abeja producida en un sistema lechero en base a pastura de alfalfa (composición fisicoquímica, palinológica y sensorial)
(2014)El objetivo de este estudio fue caracterizar mieles producidas en apiarios localizados en el centro de la provincia de Santa Fe, Argentina. Durante cinco campañas se analizaron fisicoquímica, palinológica y sensorialmente ... -
Automatic classification of legumes using leaf vein image features
(2014-01)In this paper, a procedure for segmenting and classifying scanned legume leaves based only on the analysis of their veins is proposed (leaf shape, size, texture and color are discarded). Three legume species are studied, ... -
Multiscale recognition of legume varieties based on leaf venation images
(2014-08)In this work we propose an automatic low cost procedure aimed at classifying legume species and varieties based exclusively on the characterization and analysis of the leaf venation network. The identification of leaf ... -
Environmental assessment of maize production alternatives: Traditional, intensive and GMO-based cropping patterns
(2015-10)The evolution of maize production patterns in Argentina is evaluated over the last 25 years to compare costs, benefits, environmental performance and sustainability as well as to identify the main driving sources and ... -
Time to re-think the GMO revolution in agriculture
(2015-03)Seeds of major crop cultivars provide a vital genetic and cultural link from one human generation to the next. Information embodied in seed is essential to continuity of food production, adaptation to changing climate, and ... -
How land allocation and technology innovation affect the sustainability of agriculture in Argentina Pampas: an expanded life cycle analysis
(2015-12)Pampas region grows more than 80% of Argentina's main crops, with maize (Zea maiz L.), soybean (Glycine max L. Merr.) and wheat (Triticum aestivum L.) producing crop and landscape homogeneity that reduces biodiversity, ... -
Spotted fever group rickettsiae in Amblyomma ticks likely to infest humans in rural areas from northwestern Argentina
(2015)This work was performed to detect Rickettsia species of the spotted fever group in Amblyomma ticks likely to infest humans in rural areas from northwestern Argentina. Free-living ticks were collected and determined as ... -
Does biological nitrogen fixation modify soybean nitrogen dilution curves?
(2018)Biological nitrogen fixation (BNF) in soybean [Glycine max (L.) Merr.] represents, on average, 60% of total nitrogen (N) uptake. Nitrogen dilution curves link aboveground crop N concentration (%N) to biomass accumulation (W). ... -
Effect of high-pressure treatment on hard cheese proteolysis
(2016-06)The application of high hydrostatic pressure (HHP) treatment has been proposed to reduce the ripening time of cheese via modifications in the enzymatic activities or the substrate reactivity. Investigations on the effect ... -
Intensive Soybean Management : an Integrated Systems Approach
(2017)Ecological intensification impacted soybean yield, biomass and N uptake. Narrow row spacing, high seeding rate, other best production practices, and balanced nutrition increased partitioning effi ciency for biomass, measured ... -
A modification of the arcsine–log calibration curve for analysing soil test value–relative yield relationships
(2017-03)This article aims to discuss the arcsine–log calibration curve (ALCC) method designed for the Better Fertiliser Decisions for Cropping Systems (BFDC) to calibrate relationships between relative yield (RY) and soil test ... -
Plant stand, nodulation and seed yield in soybean as affected by phosphate fertilizer placement, source and application method
(2013-11)Establishing an optimum plant population at planting is the start-point for assuring seed yield in crops. In addition to plant establishment, the onset of a fully functional nodule system is crucial for nitrogen nutrition ... -
Nutrient partitioning and stoichiometry in soybean: A synthesis-analysis
(2017-01)On-farm attainable soybean yields are primarily limited by nutrient and water supply. High-yielding soybeans is related to high nutrient uptake. A proposed theoretical framework underpinning yield formation includes plant ... -
N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ...
