Herbicide-mediated promotion of Lotus tenuis (Waldst. & Kit. ex Wild.) did not influence soil bacterial communities, in soils of the Flooding Pampa, Argentina
(2016-02)Promoting the forage Lotus tenuis is an appealing alternative to meet the needs for cattle production in the Flooding Pampa region, Argentina. This agricultural practice requires herbicides application to remove plant ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
(Wiley, 2016-03)Two experiments were carried out to examine in vitro quality and in vivo fertility of rabbit semen diluted in ultra‐high temperature (UHT) skim milk. In the first experiment, pooled ejaculates of 10 adult rabbits were ... -
Distribution of bovine herpesvirus type 1 in the nervous system of experimentally infected calves
(Elsevier, 2016-03)Bovine herpesvirus type 1 (BoHV-1) is responsible for respiratory and genital disease in cattle. BoHV-1 encephalitis is only occasionally reported. However, several cases of neurological disease have been recently attributed ... -
Survival, reproduction, avoidance behavior and oxidative stress in the earthworm Octolasion cyaneum exposed to glyphosate
(2016-03)The massive use of glyphosate (GLY) in several countries has increased the interest in investigating its potential adverse effects in non-target organisms. The aim of the present study was to assess the potential effects ... -
Cuantificación de las brechas de rendimiento de soja, trigo y maíz de Argentina.
(2016-03)En esta tesis se cuantificó cuanto más grano puede producirse en Argentina sin expandir el área cultivada reduciendo las brechas de rendimiento (i.e. diferencia entre el rendimiento potencial en secano (RPS) y el rendimiento ... -
Identificación y validación de variables asociadas con la susceptibilidad al vuelco en trigo pan en el sudeste bonaerense.
(2016-03)El vuelco es la pérdida de la posición vertical normal de los tallos y uno de los obstáculos para el alcance del rendimiento potencial en trigo pan, por lo que es necesario generar variedades de buen comportamiento. En ... -
Variabilidad espacial de suelo a escala de lote y su relación con los rendimientos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-03-23)El manejo sitio-específico dentro de un lote requiere delimitar zonas homogéneas. Múltiples variables, tales como algunas propiedades del suelo, son usadas para la zonificación. El análisis de “cluster fuzzy k-means” (CFK) ... -
