Aplicación de fósforo en secuencias agrícolas en siembra directa en hapludoles énticos = Phosphorus fertilization in crop sequences in entic hapludolls
(Asociación Argentina de la Ciencia del Suelo, 2016)Los contenidos de fósforo (P) extractable de la mayoría de los suelos de la región pampeana disminuyeron al intensificarse su extracción con cultivos y pasturas. Son frecuentes los sitios con limitaciones en P que requieren ... -
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 ... -
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 ... -
Modeling economic-environmental decision making for agricultural land use in Argentinean Pampas
(2016-03)This research evaluates the economic and environmental impacts of land allocation to crops and extensive livestock production in the Argentine Pampas using compromise programming. Two economic indicators (gross margin, ... -
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 ... -
Efecto del SNP 3702G>A del gen IGF2 sobre caracteres de crecimiento, canal, físicos-químicos y sensoriales de la calidad de carne en cerdos de la raza Landrace
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-04-13)El progreso genético alcanzado durante las últimas décadas en los caracteres de productividad y, en especial, en el aumento del contenido de magro en las canales, ha desembocado en un deterioro en los caracteres intrínsecos ... -
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 ... -
The herbage productivity of tall fescue in the Pampas region of Argentina is correlated to its ecological niche
(Wiley, 2016-09)Since its introduction in the 1950s, tall fescue has spread throughout the Pampas region of Argentina to become naturalized in much of this region. Its annual forage mass productivity shows significant differences among ... -
Kernel weight in maize: genetic control of its physiological and compositional determinants in a dent × flint-caribbean RIL population
(Maydica-ist Sper Cerealicoltur, 2016-12)The genetic control of maize kernel weight (KW) determination could be studied through its physiological and/ or compositional determinants. Our objective was to dissect the genetic control of maize KW by analyzing its ... -
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. ... -
Elementos traza en el arroyo Pergamino y su relación con el uso del suelo = Trace elements in Pergamino stream and its relationship with land use
(Asociación Argentina de la Ciencia del Suelo, 2017)Los cambios de uso de la tierra pueden provocar modificaciones más o menos profundas en la calidad de los cursos de agua. El vertido de elementos traza (ET) en dichos cursos se suma a los aportes realizados por los procesos ... -
Germinación y residuos de plaguicida en semillas de coriandro (Coriandrum sativum L.) cultivadas con aplicación de glifosato y paraquat en precosecha = Germination and residue of pesticide in coriander seeds (Coriandrum sativum L.) cultivated with pre-harvest application of glyphosate and paraquat
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2017)Es conocida la aplicación de desecantes, para acelerar y uniformizar el secado del cultivo de coriandro y de las malezas, que facilitan la cosecha de semillas. Para conocer sus efectos sobre el poder germinativo y ... -
Comparación de índices de riesgo de lixiviación de plaguicidas = Comparison of risk leaching pesticide indexes
(Asociación Argentina de la Ciencia del Suelo, 2017)El empleo de plaguicidas se considera una de las principales causas de contaminación del agua subterránea por lixiviación en áreas bajo producción agrícola. Los objetivos de este trabajo fueron: a) estimar el riesgo de ... -
Toasting time and cooking formulation affect browning reaction products development in corn flakes
(2017-03)During toasting, the last stage of corn flake production, Maillard reaction takes place, favored by the high temperature and low water content. The cooking formulation ingredients influence color and flavor of the final ... -
Standardization of Immunobiological Assay for Determines Identity of Junin virus Vaccine, Candid#1
(2017-04)The quality control tests of the Candid#1 vaccine required for internal release needs the use of rabbit immune serum (RIS). It is a biological reagent produced in INEVH and it must be qualied to ensure its proper use. ... -
Modelling spatial trends in sorghum breeding field trials using a two-dimensional P-spline mixed model
(Springer, 2017-04)A flexible and user-friendly spatial method called SpATS performed comparably to more elaborate and trial-specific spatial models in a series of sorghum breeding trials. Adjustment for spatial trends in plant breeding field ... -
Changes of starch composition by postflowering environmental conditions in kernels of maize hybrids with different endosperm hardness
(2017-05)Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ... -
