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, ... -
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). ... -
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 ... -
Identifying sulfur deficient fields by using sulfur content; N:S ratio and nutrient stoichiometric relationships in soybean seeds
(2012-08)Sulfur (S) fertilization has increasingly become an important issue in crop management. In Argentina S deficiencies have been reported, but there has been no success in finding soil tests for predicting soybean response ... -
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ... -
Estrategias de comunicación para la articulación investigación - extensión. Vínculos y construcción de sentido en torno al concepto de interdisciplina en equipos de trabajo
(Ediciones INTA, 2008)Este estudio se propone mostrar el modo en que la construcción de sentido en torno al concepto de interdisciplina en equipos de trabajo, es eje de un proceso de comunicación que acompaña cambios organizacionales. Dichos ... -
La calidad del agua subterránea en el distrito Monje (Departamento San Jerónimo) Santa Fe
(EEA Oliveros, 2017)La inquietud existente a nivel de la población de diversos centros urbanos y rurales, dentro de la región sojera núcleo de la provincia de Santa Fe, referida a la calidad del agua de consumo y sobre la posibilidad de la ... -
Coeficientes de cultivos para los principales cultivos extensivos de la Región Pampeana
(EEA Oliveros, 2017)Si bien existen Kc (coeficiente de cultivo único) generales de distintos cultivos publicados por la FAO, son muy pocos los obtenidos regionalmente en el país. Por tal motivo, el objetivo de este trabajo fue determinar los ... -
Control integrado de parásitos gastrointestinales en recría de terneras en el sur Santa Fe. Cría bovina intensiva
(EEA Oliveros, 2017)Objetivo: Validar la estrategia de “limpieza de larvas en pasturas” con vacas adultas previo al pastoreo de las recrías, disminuyendo el uso de drogas antiparasitarias con un manejo integrado de las categorías. Fundamentación: ... -
Deficiencias de cobre en rodeos de cría bovina en Venado Tuerto, Santa Fe
(EEA Oliveros, 2017)Las vacas de cría tienen elevadas exigencias para mantener su producción, para ello es importante cubrir en su dieta diaria todas las necesidades nutricionales. Entre los microelementos, el Cobre (Cu) debería estar presente ... -
Efecto de dos coadyuvantes en el control de malezas en barbecho químico con dos técnicas de pulverización terrestre
(EEA Oliveros, 2017)El objetivo de este trabajo fue evaluar el desempeño de dos coadyuvantes, adicionados a la mezcla de tanque con los herbicidas glifosato y 2,4-D sal amina, utilizando dos técnicas de pulverización terrestre y en situación ... -
