Changes in Weed Communities of Spring Wheat Crops of Buenos Aires Province of Argentina
(2014-03)During 2004 to 2008, weed surveys were conducted in 373 wheat fields of two different cropped areas (southwest [SW] and southeast [SE]) of the southern region of Buenos Aires Province of Argentina where different weed ... -
Efecto de diferentes densidades de siembra de trigo sobre la interferencia de Avena fatua L. en diferentes sistemas de siembra
(Asociación Argentina de Ciencia de las Malezas (ASACIM), 2021-06)El objetivo de este trabajo fue evaluar el efecto de dos sistemas de siembra y tres densidades de siembra de trigo (150, 300 y 400 semillas útiles m-²) sobre la competitividad de la maleza y el rendimiento del cultivo ... -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
(2018-06)Most popular emergence prediction models require species-specific population-based parameters to modulate thermal/hydrothermal accumulation. Such parameters are frequently unknown and difficult to estimate. Moreover, such ... -
Habilidad competitiva de verdeos de invierno frente a Raphanus sativus
(Asociación Argentina de Ciencia de las Malezas (ASACIM), 2024-07)El empleo de cultivos competitivos surgió como una alternativa en el control de malezas ante las presiones económicas y sociales actuales. El objetivo del trabajo fue determinar si existen diferencias en la habilidad ... -
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 ... -
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 ... -
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 ...
