Operational planning of herbicide-based weed management
(2013-10)Weeds cause crop yield loss due to competition, interfere with agricultural activities and reduce grain quality due to seed contamination. Among the numerous methods for weed control, the use of herbicides is the most ... -
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 ... -
Resistance mechanisms to 2,4-D in six different dicotyledonous weeds around the world
(MDPI, 2020)2,4-D resistance is increasing around the world due to both transgenic crops and resistance to other herbicides. The objective of the this study was to characterize the currently unknown mechanisms of 2,4-D resistance in ... -
Rust expression browser: an open source database for simultaneous analysis of host and pathogen gene expression profiles with expVIP
(BMC, 2021-03)Transcriptomics is being increasingly applied to generate new insight into the interactions between plants and their pathogens. For the wheat yellow (stripe) rust pathogen (Puccinia striiformis f. sp. tritici, Pst) RNA-based ... -
Seasonal changes in habitat use and behavior of the threatened Pampas meadowlark Leistes defilippii
(Sage Publications, 2024-06)The Pampas grasslands’ biodiversity is severely threatened by habitat modification, as is the case for the Pampas meadowlark (Leistes defilippii). Here we study the areas used by the species throughout the year in the ... -
Seed germination of five Prosopis shrub species (Fabaceae-Mimosoideae) from the Monte and Patagonia phytogeographic provinces of Argentina
(2017-12)The Patagonian species of the genus Prosopis exhibit distinctive features such as their shrub growth pattern. However, morphological or physiological differences among them have been poorly studied (e.g., germination). ... -
Selección de bandas e índices espectrales relacionados con la profundidad efectiva de los suelos en la región Pampeana Austral de Argentina
(Ediciones INTA, 2020-12)El sudoeste de la provincia de Buenos Aires (Argentina) se caracteriza por la presencia de un horizonte subsuperficial calcáreo que limita la exploración radical de los cultivos y la captación de agua. El objetivo del ... -
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 ... -
Soil physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
(2018-09)This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ... -
Tannin-containing legumes and forage diversity influence foraging behavior, diet digestibility, and nitrogen excretion by lambs
(Oxford University Press, 2019-09)Diverse combinations of forages with different nutrient profiles and plant secondary compounds may improve intake and nutrient utilization by ruminants. We tested the influence of diverse dietary combinations of tannin- ... -
Terminación de novillos británicos en pastoreo, suplementados con grano de sorgo alto en taninos = Finishing of British steers under grazing conditions, supplemented with high-tannin sorghum grain
(Estación Experimental de Pastos y Forrajes Indio Hatuey (Cuba), 2013)El objetivo de este experimento fue terminar novillos británicos con 18 meses de edad y 380 kg de PV, con el menor costo de producción posible. Además se evaluó el impacto del grano de sorgo alto en taninos, en la producción ... -
The source and market development of a premium product – Beef from the Argentine Pampas
(Elsevier, 2008-07)The two main features of beef from the Argentine Pampas are its quality and geographical origin. In addition to the normal aspects of meat quality detected by sensory panels or measured by scientific instruments, the quality ... -
The Use of Temperate Tannin Containing Forage Legumes to Improve Sustainability in Forage–Livestock Production
(MDPI, 2021-11-09)Greenhouse gas emissions from ruminant livestock production systems contribute significantly to the environmental footprint of agriculture. Emissions are lower for feedlot systems than for grass-based systems primarily ... -
Towards an integrated weed management decision support system: A simulation model for weed-crop competition and control
(Elsevier, 2020)A mathematical simulation model for the multi-annual assessment of Integrated Weed Management strategies is presented. The model allows the simulation of the competitive interaction between annual weeds and crops. For weed ... -
