Analysis of storage conditions of a wheat silo-bag for different weather conditions by computer simulation
(Elsevier, 2013-12)A validated mathematical model was used to analyse grain storage condition and determine the change in concentration of CO2 in a silo-bag holding wheat from summer to winter for a typical productive region with sub-tropical ... -
Pollen‐mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense Bitter under experimental field conditions in Argentina
(Wiley, 2013-12)The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber‐bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ... -

Un método simple y práctico para la determinación de densidad aparente
(2014)La condición física del suelo es fundamental para definir su calidad/salud y es afectada por el uso. Por ello, es necesario el seguimiento de los cambios en la condición física de los suelos bajo producción, a través de ... -
Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
(2014)No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations ... -
Efectos de Carbaryl y Metaldehído sobre Armadillidium vulgare (Crustacea: Isopoda) y Milax gagates (Mollusca: Pulmonata) en soja bajo siembra directa
(2014)Los objetivos fueron evaluar la eficacia de control y las dosis de los cebos Metaldehído 4% + Carbaryl 8% (2, 4 y 6 kg ha-1), Carbaryl 8 %, y Metaldehído 4 % y 5 % (2 y 4 kg ha-1) sobre Armadillidium vulgare y Milax gagates ... -
Nitrógeno incubado en anaerobiosis y carbono orgánico en suelos agrícolas de buenos aires
(2014)El carbono orgánico (CO) y el nitrógeno (N) incubado en anaerobiosis (Nan) son indicadores de calidad del suelo. Además, el Nan es un estimador del aporte de N por mineralización, y ha sido empleado para el ajuste de la ... -
The application of K phosphites to seed tubers enhanced emergence, early growth and mycorrhizal colonization in potato (Solanum tuberosum)
(Scientific Research, 2014-01)Rapid emergence and a vigorous growth prevent the seed tubers from infections by soil microbes and allow a rapid interception of solar radiation. In this work, the effect of the potassium phosphites (KPhi) applied to seed ... -
Inflammatory infiltration into placentas of Neospora caninum challenged cattle correlates with clinical outcome of pregnancy
(BMC, 2014-01)Infection with Neospora caninum stimulates host cell-mediated immune responses, which may be responsible for placental damage leading to bovine abortion. The aim of this study was to compare immune responses in the bovine ... -
Patterns of resource use efficiency in relation to intra-specific competition, size of the trees and resource availability in ponderosa pine
(Elsevier, 2014-01-15)Patterns of resource use efficiency (RUE) in relation to intra-specific competition, size of the trees and resource availability are under debate. Also, the relationship between RUE and growth efficiency (GE) seems to be ... -
Concepts and methods for landscape multifunctionality and a unifying framework based on ecosystem services
(Springer, 2014-02)The potential of landscapes to supply multiple benefits to society beyond commodities production has received increasing research and policy attention. Linking the concept of multifunctionality with the ecosystem services ... -
Effect of gaseous atmosphere on different supplementation medium for In Vitro canine oocyte maturation
(Bentham Open, 2014-02)The aim of the present research was to verify the influence of two different atmosphere gases (A: 5%CO2, B: 5%CO2, 5%O2 and 90%N2) on three different maturation media on in vitro maturation (IVM) rates for oocytes from ... -
Efecto de la fertilización nitrogenada en soja intersembrada en trigo en Balcarce
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)Es sabido que la soja intersembrada en trigo tiene bajo crecimiento inicial, lo cual podría afectar negativamente la formación de nódulos fijadores de nitrógeno (N) y limitar el crecimiento de la soja luego de la cosecha ... -
PLPKI: A novel serine protease inhibitor as a potential biochemical marker involved in horizontal resistance to Phytophthora infestans
(Wiley, 2014-04)Potato leaves infected with Phytophthora infestans produced a serine protease inhibitor (PLPKI) with specificity for microbial proteases. Sequencing of the first twenty residues at the NH2‐terminus of the mature PLPKI ... -
