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, ... -
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 ... -
Informes de Mercado, su uso en la Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2020)La economía neoclásica considera al agente decisor que maximiza su utilidad y las empresas sus ganancias sobre la presencia de información completa y relevante. El productor agropecuario debe dar respuesta a los interrogantes ... -
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 ... -
Maize nitrogen management in soils with influencing water tables within optimum depth
(Wiley, 2020-10)The central temperate Argentinean region is currently affected by rising water tables, allowing higher and more stable maize yields (Zea mays L) when they fluctuate within optimum depth. However, limited information was ... -
Masas de aire y patrones de circulación asociados a la ocurrencia de deficiencias hídricas severas durante el período crítico de maíz
(Ediciones INTA, 2020-12)En estudios referentes a fenómenos meteorológicos asociados a una región, la Climatología Sinóptica permite analizar las interacciones existentes entre la circulación atmosférica y las condiciones presentes en superficie. ... -
Mejoramiento de arveja (Pisum sativum L): avances del Programa de Mejoramiento Genético de la Universidad Nacional de Rosario = Pea (Pisum sativum L.) breeding: advances of the Breeding Program at Universidad Nacional de Rosario
(Sociedad Argentina de Genética, 2021-12)En 2005 se inició un programa de mejoramiento de arveja para aumentar la producción en cantidad y calidad en la Facultad de Ciencias Agrarias (FCA), Universidad Nacional de Rosario (UNR). Los primeros pasos fueron reunir ... -
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 ... -
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 ... -
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 ... -
New insights into soybean biological nitrogen fixation
(American Society of Agronomy, 2018-08)Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ... -
Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(Elsevier, 2020-05)Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ... -
Nitrogen balance in a plant-soil system under different cover crop-soybean cropping in Argentina
(2018-10-10)Cover crops (CC) provide many benefits for the soil and the following crop but their effects on nitrogen (N) release and balance in continuous no-tillage soybean (Glycine max L. Merr.) production are little known. Estimation ... -
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 ... -
Nutritional and environmental effects on biological nitrogen fixation in soybean: a meta-analysis
(Elsevier, 2019-07)Biological N2 fixation (BNF) and mineral soil absorption are complementary N sources for soybean growth. BNF is sensitive to nutrient and environmental conditions, though a comprehensive synthesis of the studies underlying ... -
Objectives and modern techniques in pea (Pisum sativum L.) breeding in Argentina: A review
(Ediciones INTA, 2023-12)Pea is considered an essential component of sustainable farming systems. The main objective of pea researchers in Argentina and worldwide is to improve yield components and composition of the seed to enhance nutritional ... -
