¿Estamos frente a un cambio de actores en el alquiler de tierras para cosecha en el Norte de la provincia de Buenos Aires?
(2015-11)Hacia finales del siglo pasado y principios del actual en la zona agrícola núcleo, facilitado por el alquiler de tierras para cosecha, se profundizó el proceso de crecimiento de escala de las empresas agropecuarias y de ... -
Root depth: a trait to increase water use and yield of wheat
(Australian National University, 2015-11)Crops with deeper roots could potentially capture more soil resources and as a consequence yield more. However, as sampling roots by soil coring is challenging, there are few examples of genetic diversity determined under ... -
Determinación del Costo Ambiental Asociado a los Balances de Nitrógeno y Fósforo en Sistemas Agropecuarios del Partido de Pergamino
(2015-11)La alteración de los ciclos de los principales nutrientes es un aspecto clave en la caracterización ambiental de los sistemas de producción agropecuaria en distintas regiones del mundo. Este trabajo se propone estudiar los ... -
Comercialización de soja en la últimas dos décadas : mercado disponible vs. mercado de futuros
(2015-12)El agente decisor sobre la producción agropecuaria debe identificar los momentos de precios elevados a fin de obtener un buen precio de venta de su producción. Sin embargo, el agente tomador de decisión posee limitaciones ... -
Physical and mechanical properties of maize extrudates as affected by the addition of chia and quinoa seeds and antioxidants
(2015-12)The physical and mechanical properties of maize extrudates have been analyzed in relation to the addition of quinoa flour and two novel ingredients, chia and powder extract of purple corn with antioxidant properties. Maize ... -
Gene action controlling stability and adaptability in maize
(2016)Limited knowledge about the genetic merit of maize landraces contributes to their little use in breeding, al-though some reports pointed them as a source of useful alleles. Repeated cultivation of landraces ... -
Germination and infection of Phakopsora pachyrhizi under simulated environment of the central area of Santa Fe, Argentina
(2016)Soybean asian rust (SAR) caused by the fungus Phakopsora pachyrhizi was confirmed in Argentina for the first time during the 2002-2003 growing season. Then, the disease spread to the Northern and Eastern provinces, reaching ... -
Soil microbial functionality in response to the inclusion of cover crop mixtures in agricultural systems
(2016)Agricultural systems where monoculture prevails are characterized by fertility losses and reduced contribution to ecosystem services. Including cover crops (CC) as part of an agricultural system is a promising choice in ... -
Antioxidant characterization of new dietary fiber concentrates from papaya pulp and peel (Carica papaya L.)
(2016)Residues of papaya pulp and peel were used to produce dietary fiber concentrates (DFCs) by treatment with ethanol and microwave drying. The fiber showed antioxidant capacity. Phenolics, carotenoids and ascorbic acid were ... -
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 ... -
Diagnóstico y manejo de enfermedades en girasol
(Ediciones INTA, 2016)El cultivo de girasol en la Argentina se encuentra en una fase de retracción en el área cultiva y en la producción, observando una alta competencia de la soja, y de la cebada, y en los últimos ciclos, de relativas bajas ... -
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 ... -
Effect of cover crops on microbial community structure and related enzyme activities and macronutrient availability
(2016)Continuous monoculture in major agricultural regions has been characterized by the loss of fertility, increased soil erosion and surface runoff. Thus, the inclusion of cover crops (CC) is a promising option aimed at better ... -
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 ... -
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 ... -
Cancro del tallo en girasol (Helianthus annus L.) causado por el complejo Diaporthe/Phomopsis helianthi Munt.-Cvetk
(EEA Pergamino, 2016-02)El cancro del tallo en girasol (CTG) es causado por el complejo Diaporthe/ Phomopsis helianthi. En Argentina el CTG fue observado en la zona centro-norte de la provincia de Buenos Aires en 1994 y en Entre Ríos en 1995 . ...
