(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
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 ... -
Caracterización de poblaciones nativas de maíz mediante análisis de procrustes generalizado y análisis factorial múltiple
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2012)El establecimiento de relaciones entre taxones es un paso esencial en el proceso de catalogación y evaluación del material conservado en un Banco de Germoplasma. Existen distintos métodos de evaluación en función del tipo ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
Characterization of maize populations in different environmental conditions by means of Three-Mode Principal Components Analysis
(Facultad de Agronomía e Ingeniería Forestal, Pontificia Universidad Católica de Chile, 2010-12)Characterization of 31 native populations of maize conserved at the germplasm bank of the INTA Pergamino Experimental Station, Argentina, was achieved by evaluating 10 quantitative attributes in two different environmental ... -
Heredabilidad, correlaciones genéticas, análisis de sendero e índices de selección en una población de girasol (Helianthus annuus) de la EEA INTA Pergamino
(Ediciones INTA, 2021-08)El primer paso en un programa de desarrollo de cultivares es formar una población con variabilidad genética para los caracteres de interés. La selección de progenies provenientes de poblaciones constituye una valiosa ... -
Evaluación de dos cruzamientos experimentales de tres vías de pollo campero bajo dos manejos de la alimentación
(Sociedad de Medicina Veterinaria del Uruguay, 2019-12-01)El pollo campero es un ave con menor velocidad de crecimiento y mayor rusticidad que el pollo parrillero industrial, y está destinado a sistemas de producción semi-intensiva que contemplan aspectos vinculados con el bienestar ... -

(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2019-04-05)El pollo Campero representa una alternativa productiva en el marco de sistemas avícolas semi-intensivos que buscan preservar el bienestar animal. El protocolo de producción establece restricciones vinculadas con estrategias ... -
A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize
(Springer Nature, 2021-06-12)The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make ... -
