(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 ... -
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) ... -
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 ... -
Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
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, ... -
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 ... -
El nabo como recurso forrajero invernal en la producción de carne
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)El objetivo del trabajo fue evaluar la producción de carne con nabo forrajero (Brassica napus x B. oleracea cv Interval) en cultivo puro y en mezcla con avena bajo pastoreo con novillitos a fines del invierno. El experimento ... -
Efectos de diferentes estrategias de fertilización sobre los rendimientos, el balance de nutrientes y su disponibilidad en los suelos en el largo plazo
(IPNI, 2015-09)A nivel productivo, las deficiencias de nitrógeno (N), fósforo (P) y azufre (S) no ocurren de manera aislada sino que se combinan de diversas maneras, por lo que es necesario evaluar integralmente la respuesta a la ... -
Structure of the novel monomeric glyoxalase I from Zea mays
(International Union of Crystallography, 2015-10)The glyoxalase system is ubiquitous among all forms of life owing to its central role in relieving the cell from the accumulation of methylglyoxal, a toxic metabolic byproduct. In higher plants, this system is upregulated ... -
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 ... -
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 ...
