Efecto de la chinche de los cuernos "Dichelops furcatus" [F.] sobre la calidad de la semilla de soja
(2013)La “chinche de los cuernos” Dichelops furcatus (F.) ha aumentado notablemente su abundancia relativa en relación a los demás hemípteros que atacan al cultivo de soja, llegando incluso a estar como especie dominante en los ... -
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 ... -
Costos ambientales y eficiencia productiva en la producción agraria del partido de Pergamino
(2013)Mediante un modelo de frontera de producción estocástica se analizó el nivel de eficiencia técnica para la producción de soja, maíz y trigo en empresas agropecuarias del partido de Pergamino, Buenos Aires, Argentina. El ... -
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 ... -
Transcriptional and metabolic changes associated to the infection by Fusarium verticillioides in maize inbreds with contrasting ear rot resistance
(2013)Fusarium verticillioides causes ear rot and grain mycotoxins in maize (Zea mays L.), which are harmful to human and animal health. Breeding and growing less susceptible plant genotypes is one alternative to reduce these ... -
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 ... -
Crecimiento del pinus radiata sometido a diferentes tratamientos de raleo y poda en el sudeste de la provincia de Buenos Aires, Argentina
(2015)Los tratamientos silvícolas orientados a la producción de madera de calidad tienen como finalidad concentrar la producción volumétrica en los mejores individuos. Atendiendo a la falta de información local previa, el objetivo ... -
Relationship between MODIS-NDVI data and wheat yield : a case study in northern Buenos Aires province, Argentina
(2015-07-18)In countries like Argentina, whose economy depends heavily on crop production, the estimation of harvests is an elementary requirement. Besides providing objectivity, the use of remote sensing allows estimating yield in ... -
Projection of soil organic carbon reserves in the Argentine Rolling Pampa under different agronomic scenarios. Relationship of these reserves with some soil properties
(Bentham Open, 2015)The soil organic carbon (SOC) of the Argiudolls of the Argentine Rolling Pampa evolves rapidly. Currently, the soils richest in SOC are cultivated with intensified crop sequences (e.g. maize-double cropped wheat/soybean, MWS) ... -
Fruiting efficiency : an alternative trait to further rise wheat yield
(2015-07)Further improvements in wheat yields are critical, for which increases in grain number would be required. In the recent past, higher grain number was achieved through increased growth of the juvenile spikes before anthesis, ... -
Estimación de la biomasa aérea en árboles y rodales de Eucalyptus viminalis Labill = Estimation of aerial biomass in Eucalyptus viminalis Labill trees and stands
(2014-12)Los modelos de biomasa resultan herramientas de aplicación directa para su estimación en diferentes compartimentos y aplicables a estudios ambientales de fijación de CO2, a la determinación de la biomasa maderable y de la ... -
Genetic variability within accessions of the B73 maize inbred line
(2014)The maize inbred line B73 has been extensively studied at the molecular level. Researchers now have access to the genome sequence of B73 as well as to databases of biallelic and multiallelic markers where functional ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
(2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ... -
Genetic relatedness and population structure within the public Argentinean collection of maize inbred lines
(2014)Genetic diversity of an Argentinean public temperate inbred maize collection has not been previously assessed. This collection includes mainly locally developed orange flint germplasm and a group of temperate inbred lines ... -
Efecto de tiempos de imbibición y soluciones aplicadas en el priming sobre el comportamiento germinativo de semillas de coriandro
(2013-09)Coriander produces seeds with heteregeneous maturity range at harvest and long germination period. The priming is a technique to improve speed and uniformity of germination. Were evaluated effects on germination of seed ... -
Genetic diversity and linkage disequilibrium in the Argentine public maize inbred line collection
(2017)Knowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. ... -
Quantitative trait loci for Fusarium and Gibberella ear rot resistance in Argentinian maize germplasm
(2016)Fusarium verticillioides and F. graminearum cause ear rots in maize (Zea mays L.) that reduce yield and contaminate the grain with mycotoxins produced by the fungi. To map QTLs for resistance to these ear rots, a F5 mapping ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) is associated with a fitness penalty
(2016)The net selection effect of herbicides on herbicide-resistance traits in weeds is conditioned by the fitness benefits and costs associated with resistance alleles. Fitness costs play an important evolutionary role preventing ... -
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 ...
