Curvas de crecimiento de forrajeras templadas irrigadas
(Asociación Latinoamericana de Producción Animal, 2001)Con el objetivo de construir y comparar las curvas de distribución estacional de forraje de 15 gramíneas y leguminosas se realizaron cuatro ensayos entre 1996 y 1999. Cada uno constó de dos repeticiones compuestas cada una ... -
Producción de forraje y densidad de plantas de alfalfa irrigada comparando distintas densidades de siembra
(Asociación Latinoamericana de Producción Animal, 2002)La alfalfa es la forrajera principal en el valle bonaerense del Río Colorado, Argentina. Sin embargo, se carece de datos locales sobre la densidad de siembra (den. smb.) que asegure elevada persistencia y producción del ... -
Variabilidad espacial de fertilidad química del suelo en un diseño de bloques
(Sociedad Española de la Ciencia del Suelo, 2011)En la caracterización del estado inicial de un ensayo de larga duración bajo siembra directa, se plantea la hipótesis de que existen -en los horizontes superficiales- gradientes de fertilidad horizontal (interbloques) y ... -
Influencia del estado de madurez a cosecha sobre la calidad de semillas de alfalfa (Medicago sativa L.)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)La alfalfa (Medicago sativa L.) recién cosechada presenta dormición física debida a la dureza de sus tegumentos que puede afectar la producción de forraje en el primer año de implantación. Aunque se conoce que la temperatura ... -
Exoferality in sunflower (Helianthus annuus L.): a case study of intraspecific/interbiotype interference promoted by human activity
(2013)Helianthus annuus subsp. annuus, a biotype of the same species of the domesticated sunflower H. annuus var. macrocarpus, is an emergent noxious weed in several regions of the world. The frequent hybridization that occurs ... -
Diversity of Auchenorrhyncha (Hemiptera: Cicadellidae: Delphacidae) associated with Vicia villosa in southern Buenos Aires province, Argentina
(2014-06)Among the Hemiptera, the Auchenorrhyncha are well known owing to their phytosanitary relevance since the group includes pathogen vector species able to damage commercial crops. Vicia villosa Roth (Fabaceae) is a fodder ... -
Estudio de la densidad de trips bajo distintas formas de manejo de un cultivo de cebolla en el área de riego del valle inferior del Río Colorado, provincia de Buenos Aires, Argentina
(2014-07)Los trips constituyen la plaga primaria de la cebolla, en un cultivo ya establecido, en el área de riego del valle inferior del Río Colorado, provincia de Buenos Aires, Argentina. Algunos productores de cebolla de esta ... -
Broad resistance to acetohydroxyacid-synthase-inhibiting herbicides in feral radish (Raphanus sativus L.) populations from Argentina
(2016-02)BACKGROUND: Soon after the commercial release of sunflower cultivars resistant to imidazolinone herbicides, several uncontrolled feral radish (Raphanus sativus L.) populations were found in south-eastern Buenos Aires, ... -
Can achene selection in sunflower crop–wild hybrids by pre-dispersal seed predators hasten the return to phenotypically wild sunflowers
(2016-04)Bird attack is a serious limitation to sunflower yield in several regions of the world, but it could also cause selection. The wild Helianthus annuus, naturalized in several regions of the world, hybridizes with the crop ... -
Cold stress tolerance during early growth stages of naturalized Helianthus petiolaris populations
(2016-07)In the last 10 years the sunflower crop area of Argentina has shifted towards the Southwest as a result of the expansion of soybean cultivation. Early sowings require greater tolerance to low temperatures in order to ... -
Effect of water availability and seed source on physical dormancy break of Vicia villosa ssp. villosa
(2016-09)Physical dormancy (PY) plays a crucial role in the control of the reseeding process of Vicia villosa Roth, a winter annual species cultivated for pasture and hay, naturalized in several semi-arid temperate agroecosystems. ... -
Transgenic glyphosate-resistant oilseed rape (Brassica napus) as an invasive weed in Argentina: detection, characterization, and control alternatives
(2016-12)The presence of glyphosate-resistant oilseed rape populations in Argentina was detected and characterized. The resistant plants were found as weeds in RR soybeans and other fields. The immunological and molecular analysis ... -
IMI resistance associated to crop-weed hybridization in a natural Brassica rapa population: characterization and fate
(2017-03)Wild turnip (Brassica rapa) is a common weed and a close relative to oilseed rape (Brassica napus). The Clearfield® production system is a highly adopted tool which provides an alternative solution for weed management, but ... -
Hybrid sunflower seed yield, composition and deterioration after chemical desiccation
(2017-04)The impact of chemical desiccation on yield showed contrasting results depending on seed moisture content at the time of application. Its effects on seed deterioration are still unknown and could be modified by seed ... -
Self‐regeneration of hairy vetch (Vicia villosa Roth) as affected by seedling density and soil tillage method in a semi‐arid agroecosystem
(2017-09)Vicia villosa Roth is a forage legume with the capability for biological N fixation and natural reseeding, which could contribute to sustainability in semi‐arid regions. This study aimed to determine (i) the relationship ... -
Crop-wild sunflower hybridization can mediate weediness throughout growth-stress tolerance trade-offs
(2017-11)Agricultural weeds are plants well-adapted to agricultural environments interfering directly and indirectly with crop production and causing important economic losses worldwide. Crop-wild hybridization is one of the main ... -
Efecto de rotaciones agrícolas con cebolla sobre las propiedades químicas del suelo y producción de policultivo avena-vicia y resiembra natural de Vicia villosa Roth. en el sur de Buenos Aires
