Perennial grasses of different successional stages under various soil water inputs: do they differ in root length density?
(Asociación Interciencia, Venezuela, 2007-03)Information about root length density (RLD) on perennial grasses of different successional stages exposed to various soil water inputs is limited. The effects on RLD of different soil water inputs were evaluated in the ... -
Perennial warm-season grass monocultures and mixtures: Biomass production and soil improvement in semiarid and shallow soil conditions
(Elsevier, 2018-07)Perennial warm-season grasses (WSG) represent a viable alternative for cultivation in marginal lands. Moreover, mixtures of WSG can be expected to exceed monocultures in terms of biomass production since biodiversity and ... -
Preliminary study on parasitism of aphids (Hemiptera: Aphididae) in relation to characteristics of alfalfa fields (Medicago sativa L.) in the Argentine Pampas
(Elsevier, 2012-09-12)Alfalfa is a perennial crop and is one of the most relevant forage resources for cattle in the Argentine Pampas, with aphids (Hemiptera Aphididae), one of the main pest insects in alfalfa, being frequently attacked by a ... -
Producción y calidad del forraje de alfalfa con gramíneas megatérmicas en el año de implantación = Forage production and quality of warm season grasses associated with alfalfa in the semiarid pampas in the implantation year
(Facultad de Agronomía, UNLPam, 2014)El objetivo fue evaluar la producción de forraje, proteína bruta (PB), fibra detergente neutro (FDN) y digestibilidad estimada de la materia seca (DEMS) en pasturas asociadas de alfalfa y gramíneas C4 en comparación con ... -
Salt tolerance variability among stress‐selected Panicum coloratum cv. Klein plants
(Wiley; British Grassland Society; European Grassland Federation, 2016-11)This work assessed intracultivar variability for salt tolerance within Panicum coloratum cv. Klein, explored some physiological parameters potentially associated with it and evaluated the contribution of cell division and ... -
Sistemas genéticos y diversidad en Acroceras macrum Stapf
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2015)Acroceras macrum es una especie C3 perenne originaria de regiones húmedas, tropicales y subtropicales, de África. Sus destacables propiedades nutricionales se traducen en producción de carne, y su excelente adaptación a ... -
Soil Phosphorus Concentration under the Canopy of Perennial Grasses of Different Successional Stages Exposed to Water Stress
(Taylor and Francis, 2008-10)In this field study, the effects of water‐stress, rainfed, or irrigated conditions on soil phosphorus (P) concentration under the canopy of the native grasses of semi‐arid Argentina (late seral Stipa clarazii Ball., early ... -
Variability for salt tolerance in a collection of Panicum coloratum var. makarikariense during early growth stages = Variabilidad en tolerancia a la salinidad en una colección de Panicum coloratum var. makarikariense durante las etapas tempranas de crecimiento
(CIAT, 2018-09)Our aim was to investigate variability for salt tolerance in a collection of Panicum coloratum var. makarikariense of INTA EEA Rafaela, Argentina. Panicum coloratum is a C4 perennial grass to be potentially used to increase ... -
Water use, root activity and deep drainage within a perennial legume-grass pasture: a case study in southern inland Queensland, Australia = Uso de agua, actividad radicular y drenaje profundo en una pastura leguminosa-gramínea perenne: Un estudio de caso en el sur de Queensland, Australia
(CIAT, 2016-09)Water use and depth of water extraction of leucaena (Leucaena leucocephala) and Rhodes grass (Chloris gayana) pasture, irrigated with desalinated coal seam water (a by-product of the coal seam gas industry), were monitored ... -
Weed effects on the establishment and nutritive value of pastures with different annual/perennial ratio
(Wiley, 2020-12)Livestock intensification is increasing weed invasion in pastures. We performed an experiment near Buenos Aires, Argentina, to evaluate the impact of weeds on temperate cultivated pastures. We sowed 1,700 viable seeds m–2 ...
