Effects of crop and weed densities on the interactions between barley and Lolium rigidum in several Mediterranean locations
(Institut national de la recherche agronomique (França)EDP Sciences, 2003)The effects of both barley and Lolium rigidum densities on weed growth and spike production and on crop yield were examined in five field experiments carried out in the Mediterranean drylands of Spain and Western Australia. ... -
Effects of livestock management on carbon stocks and fluxes in grassland ecosystems in the Pyrenees
(European Grassland Federation, 2004)Grassland ecosystems can constitute a source or a sink in the global C balance, and their management affect their position in that balance. We aim to assess soil organic carbon (SOC) content and determine how grazing affects ... -
Efficiency, profitability and carbon footprint of different management programs under no-till to control herbicide resistant Papaver rhoeas
(MDPI, 2020-04-01)The present work examines the effects of different integrated weed management (IWM) programs on multiple herbicide-resistant Papaver rhoeas populations in terms of effectiveness, profitability and carbon footprint. With ... -
El grupo de investigación de Malherbología de la Universidad de Lleida: 25 años de transferencia de conociiento al sector
(Phytoma-España, 2021)La transferencia de conocimiento constituye una actividad aca-démica menos conocida (y reconocida) que la docencia o la inves-tigación y, sin embargo, deviene uno de los mejores indicadores del papel social de las universidades ... -
Elemental composition of natural nanoparticles and fine colloids in European forest stream waters and their role as phosphorus carriers
(American Geophysical Union, 2017)Biogeochemical cycling of elements largely occurs in dissolved state, but many elements may also be bound to natural nanoparticles (NNP, 1-100 nm) and fine colloids (100-450 nm). We examined the hypothesis that the size ... -
Elementos florísticos de las sierras marginales de los prepirineos centrales catalanes
(Real Jardin Botanico, 1996)Las sierras marginales de los Prepirineos centrales catalanes están formadas por un conjunto de alineaciones de dirección oeste-este que se extienden desde el sur del Montsec hasta la depresión del Ebro. -
Emergence modelling of 18 species susceptible to be used as cover crops in Mediterranean semiarid vineyards
(Elsevier, 2022-01)Cover Crops (CC) are increasingly appreciated in vineyards because they can provide ecosystems services, such as preventing soil erosion and compaction, increasing soil organic matter or, controlling weeds. Many species ... -
Emergence of field pennycress (Thlaspi arvense L.): Comparison of two accessions and modelling
(Elsevier B.V., 2015)Many weed species are becoming rare due to intense agricultural management, which leads to a decrease of biodiversity in agroecosystems. Cultivating some of these species for their oilseed content may help preserve them ... -
Emergence patterns of rare arable plants and conservation implications
(MDPI, 2020-03-01)Knowledge on the emergence patterns of rare arable plants (RAP) is essential to design their conservation in Europe. This study hypothesizes that is possible to find functional groups with similar emergence patterns within ... -
Enhanced 2,4-D metabolism in two resistant papaver rhoeas populations from Spain
(Frontiers Media, 2017-07-13)Corn poppy (Papaver rhoeas), the most problematic broadleaf weed in winter cereals in Southern Europe, has developed resistance to the widely-used herbicide, 2,4-D. The first reported resistance mechanism in this species ... -
Estado actual de las resistencias de malas hierbas a herbicidas
(Mapama, 2006)En este artículo se describe la situación actual de las resistencias de las malas hierbas a los herbicidas en España. Antes, sin embargo, se hace hincapié en las principales definiciones a tener en cuenta en este ámbito. ... -
Estructura y sintaxonomía de los hayedos del valle de Gresolet
(Universitat de Barcelona, 1993)Structure and syntaxonomy of beech forests from Gresolet Valley (E Pyrenees). Six communities related to beech forest from Gresolet Valley (Alt Bergucda) arc compared, based in their structure and synsystematics. A new ... -
Estudi de la flora exòtica del riu Segre al seu pas pel Segrià. Origen i potencial invasor
(Centre d'Estudis Comarcals del Segrià, 2016)A causa del greu impacte ecològic i econòmic de la flora exòtica invasora als ecosistemes, i a la major susceptibilitat dels hàbitats riparis a les invasions biològiques, és important mantenir un coneixement actualitzat ... -
Estudio de los factores relacionados con el Bitter Pit en la zona fruticola de Lleida
