Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Combining cover crops and low nitrogen fertilization improves soil supporting functions
(2019-07)Background and aims: Cover crops may restore soil functions lost with single summer crop sequences enhancing soil organic carbon and nitrogen (SOC and SON) stocks. We investigated the effect of cover crops and low nitrogen ... -
Contrasting effects of soil type and use of cover crops on nitrogen and phosphorus leaching in agricultural systems of the Argentinean Pampas
(Elsevier, 2024-01)Agricultural systems of the Argentinean Pampas generally use rotations of summer crops under no-tillage and apply fertilization at rates that do not compensate nutrient exports with grain harvest, resulting in negative ... -
Diallel analysis of kernel weight and grain-filling traits in maize grown under contrasting nitrogen supply
(Wiley, 2023-02)Understanding the inheritance of maize (Zea mays L.) kernel weight (KW) under contrasting nitrogen (N) supply is crucial for obtaining high KW across diverse N conditions. This work evaluated broad-sense heritability (H2), ... -
Ecophysiological traits in maize hybrids and their parental inbred lines: Phenotyping of responses to contrasting nitrogen supply levels
(Elsevier, 2009-10)Maize (Zea mays L.) breeding based primarily on final grain yield has been successful in improving this trait since the introduction of hybrids. Contrarily, understanding of the variation in ecophysiological processes ... -
Environmental control of malting barley response to nitrogen in the Pampas, Argentina
(2018-04)Twenty five single-year field experiments were established in order to assess the effects of nitrogen fertilization on grain yield, size, and protein concentration, and to explain its response to fertilization with soil, ... -
Fertilización en sorgo en el norte y centro-oeste de Buenos Aires : rendimiento y eficiencia comparada al maíz
(2013-12)En este trabajo se presentan los resultados de un ensayo de respuesta del cultivo de sorgo a la aplicación de nitrógeno (N), fósforo (P), azufre (S), zinc (Zn) y boro (B) realizado en Pergamino (Buenos Aires) en la ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
Is the nutritive value of tall fescue (Festuca arundinacea Schreb.) related to the accumulated forage mass?
(Wiley, 2016-03)The aim of this work was to investigate whether neutral detergent fibre (NDF) and dry‐matter digestibility (DMD) are related to tall fescue accumulated forage mass (AFM) and to assess the relevance of environmental variables ... -
Long-term impact of no tillage in two intensified crop rotations on different soil organic matter fractions in Argentine Rolling Pampa
(2013)It is expected that the agricultural intensification occurred in recent decades in the Argentine Rolling Pampa significantly alters the SOM reserves. Therefore, it is necessary to identify soil organic carbon (C) and ... -
Maize Nitrogen Use Efficiency: QTL Mapping in a U.S. Dent x Argentine-Caribbean Flint RILs population
(2018-04)This study was aimed to identify quantitative trait loci (QTL) for nitrogen use efficiency (NUE) and related traits in a maize population derived from a cross between two lines with different genetic background (B100 and ... -
Mejores prácticas de manejo de la fertilización de trigo : dos experiencias de INTA 9 de Julio
(2013-03)Las mejores prácticas de manejo (MPM) de uso de fertilizantes involucran aplicar la fuente de nutriente correcta, en la dosis, el momento y el lugar correctos. Estas decisiones son críticas para alcanzar una óptima eficiencia ... -
Reducción del drenaje profundo y la lixiviación de nitrógeno en rotaciones agrícolas con cultivos de cobertura
(2016)Deep drainage and nitrogen leaching reduction in crop rotations with cover crops. Ecosystem water and nitrogen (N) fluxes can be altered by vegetation changes. The intensification of crop rotations with fall-winter cover ... -
Responses to N Deficiency in Stay Green and Non-Stay Green Argentinean Hybrids of Maize
(2016-06)Breeding has developed better yielding maize hybrids for low N environments, which also have delayed leaf senescence (‘stay green’ trait, SG). Here, we studied whether the SG trait can further improve yield of modern hybrids ... -
Source-sink relations and kernel weight in maize inbred lines and hybrids : responses to contrasting nitrogen supply levels
(Elsevier, 2019-01)Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
(Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ...
