Modeling Avena fatua seedling emergence dynamics: an artificial neural network approach
(Elsevier, 2012-10)Avena fatua is an invasive weed of the semiarid region of Argentina. Seedling emergence patterns are very irregular along the season showing a great year-to-year variability mainly due to a highly unpredictable precipitation ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
(2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Natural allelic variation confers diversity in the regulation of flag leaf traits in wheat
(Springer Nature, 2024-06)Flag leaf (FL) dimension has been reported as a key ecophysiological aspect for boosting grain yield in wheat. A worldwide winter wheat panel consisting of 261 accessions was tested to examine the phenotypical variation ... -
Natural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
(2018)Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), ... -
Natural occurrence of Alternaria mycotoxins in malting barley grains in the main producing region of Argentina
(Wiley, 2019-10)Background: Barley (Hordeum vulgare L.) is one of the most important cereals worldwide, and its quality is affected by fungal contamination such as species of the genus Alternaria. No information is available about the ... -
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- ... -
