Efecto de la cobertura de suelo con acolchados plásticos sobre el comportamiento del cultivo de alcaucil (Cynara cardunculus var. scolymus L.) = Effect of soil coverage with plastic on globe artichoke crop behavior (Cynara cardunculus var. scolymus L.)
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2017)Se evaluó el efecto de los polietilenos negros y bicapa sobre el comportamiento del cultivo de alcaucil en la zona de Rosario. Se utilizó el híbrido Madrigal y se evaluaron las variables Número de capítulos por planta, ... -
Environmentally sound resource valuation for a more sustainable international trade : case of argentine maize
(2018)This study analyzed costs and benefits for Argentina when trading maize grain. Assigning an appropriate value to traded resources involves a comprehensive assessment of all kinds of sources driving the process, in order ... -
Utilización de cultivos de cobertura en monocultivo de soja: efectos sobre el balance hídrico y orgánico
(2015-12)Los cultivos de cobertura (CC) son una alternativa para mejorar la falta de cobertura y balance de carbono (C) en suelos bajo siembra directa con monocultivo de soja (Glycine max L. Merr.), predominantes en la Región ... -
Modelo ‘‘cuanti-cualitativo’’ de escurrimiento superficial del agua en suelos agrícolas de la región Pampeana Argentina
(2016-12)Desde hace mucho tiempo se está estudiando la modelación de la relación lluvia-escurrimiento y han sido desarrollados una gran cantidad de métodos y modelos para simular la generación de escurrimiento de una lluvia. Uno ... -
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. ... -
Ponderación de la información generada en la Estación Experimental Agropecuaria Oliveros del INTA (INTA EEA Oliveros) mediante el proceso analítico jerárquico
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-08)En el siglo XXI, el subsistema de conocimiento científico-tecnológico se convirtió en el principal componente del capital cultural de un país viabilizando el desarrollo socioeconómico y la potencialidad de los países ...
