Post-grazing cutting management in tall fescue affects the sward structure, forage and liveweight production
(2019-09)Tall fescue is the main perennial grass of the pastures of the temperate region of Argentina. However, after flowering in spring, tall fescue loses productivity and quality. Based on this, the objective of this work was ... -
Predicting junglerice (Echinochloa colona L.) emergence as a function of thermal time in the humid pampas of Argentina
(Taylor & Francis, 2020-06)Junglerice (Echinochloa colona) is one of the most important annual weeds affecting crops in Argentina. A predictive seedling emergence model based on thermal time was developed and validated. Monitoring of seedling emergence ... -
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) ... -
Pronase hydrolysis as a pretreatment for quantifying Maillard intermediates during toasting of cornflakes
(ISEKI Food Association, 2016-04)Some of the products generated by the Maillard reaction are desired and very important for defining consumer acceptance of breakfast cereals. However, in recent years there has been an increased concern about compounds ... -
Prospects for plant productivity: from the canopy to the nucleus
(Oxford University Press, 2021-05)Population growth has been closely associated with agricultural production, since the first famine predicted by Malthus (1798) up to the Green Revolution of the past century. Today, we continue to face increasing demand ... -
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 ... -
Rapid autographic method for detection of enzymatic browning inhibitors based on enzyme immobilization
(2018-07)This work describes a TLC-coupled bioautographic assay suitable for the separation and detection of apple polyphenol oxidase (PPO) inhibitors from natural extracts. PPO was immobilised in agar containing L-DOPA as substrate ... -
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 ... -
Relación de conversión de alimento en cinco híbridos experimentales de pollos camperos = Feed conversion ratio in fi ve experimental hybrids of free range chickens
(Facultad de Ciencias Veterinarias de Esperanza, Universidad Nacional del Litoral, 2014)La evaluación del crecimiento dimensional de cinco híbridos experimentales de pollo campero que difi eren en su genotipo materno permitió constatar la equivalencia de las poblaciones utilizadas como madre como potenciales ... -
Relación yema: albumen en huevos de tres genotipos de gallinas ponedoras destinadas a sistemas semi intensivos
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2022-08-06)Se estudió el comportamiento dinámico de la relación yema:albumen en huevos del cruzamiento de tres vías Campero Casilda en comparación con Negra INTA y Rhode Island Red. Se trabajó con muestras aleatorias de 15 huevos de ... -
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 ... -
Relative performance of cluster algorithms and validation indices in maize genome-wide structure patterns
(Springer Nature, 2021-09)A number of clustering algorithms are available to depict population genetic structure (PGS) with genomic data; however, there is no consensus on which methods are the best performing ones. We conducted a simulation study ... -
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 ... -
Reutilizar purines de tambo como oportunidad para reciclar nitrógeno y reducir su impacto ambiental
(Asociación Argentina de Ecología, 2023-08)Los purines de tambo (excretas mezcladas con agua de las instalaciones de ordeñe) se pueden reutilizar en la producción agrícola como reemplazo de los fertilizantes sintéticos. Sin embargo, su alta concentración nitrogenada ... -
Root phenotypes at maturity in diverse wheat and triticale genotypes grown in three field experiments: Relationships to shoot selection, biomass, grain yield, flowering time, and environment
(Elsevier, 2020-09)Modelling and limited data suggest that crops with deeper and longer roots capture more soil resources and yield more when water is available deeper in soil profiles. Interest has grown in the development of new cultivars ... -
Rural landscape simplification and provision of cultural ecosystem services : a case study in the Argentine Pampas
(Universitat Politécnica de Valéncia, 2023-06)In recent decades, the rural landscape of the Argentine Pampas has undergone a process of simplification due to the increased land allocated to crops, replacing pastures and grasslands, with a substantial increase in soybean ... -
Secuencias de cultivos anuales para forraje y pastura perenne en suelo agrícola degradado
