Climate effect on Avena fatua field emergence dynamics: a 38-year experiment in the Semiarid Pampean Region of Argentina
Renzi Pugni, Juan Pablo; Traversa, Guadalupe; Vigna, Mario Raul; Chantre Balacca, Guillermo Ruben (Wiley, 2022-02)Climate events modulate weed population dynamics mainly by influencing field seedling emergence patterns. Field experiments aiming to study the influence of climate on the early-stage establishment of weeds are of utmost ... -
Development and validation of a simulation model for hairy vetch (Vicia villosa Roth) self-regeneration under different crop rotations
Renzi Pugni, Juan Pablo; Chantre Balacca, Guillermo Ruben; González-Andújar, José L.; Cantamutto, Miguel Angel (Elsevier, 2019-04)Hairy vetch (HV, Vicia villosa Roth) is a winter annual legume cultivated for pasture grazing, in crop rotations with cereal crops under semi-arid conditions. The inclusion of HV increases soil nitrogen, thus contributing ... -
Effect of water availability and seed source on physical dormancy break of Vicia villosa ssp. villosa
Renzi Pugni, Juan Pablo; Chantre Balacca, Guillermo Ruben; Cantamutto, Miguel Angel (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. ... -
Evaluation of new pasture legumes options in the Pampa-Patagonia transitional region of Argentina
Renzi Pugni, Juan Pablo; Chantre Balacca, Guillermo Ruben; Reinoso, Omar Juan; Quintana, Matias; Grand, Andres Carlos; Cantamutto, Miguel Angel (Ediciones INTA, 2022-11)Biodiversity in forage legumes adapted to semiarid-arid conditions is scarce. In the Pampa-Patagonia transitional region of Argentina (PTRA), the annual rainfall is 440 mm with annual evapotranspiration of 1690 mm. Only ... -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
Chantre Balacca, Guillermo Ruben; Vigna, Mario Raul; Renzi Pugni, Juan Pablo; Blanco, Anibal Manuel (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 ... -
Modeling Avena fatua seedling emergence dynamics: an artificial neural network approach
Chantre Balacca, Guillermo Ruben; Blanco, Anibal Manuel; Lodovichi, Mariela Victoria; Bandoni, Jose Alberto; Sabbatini, Mario Ricardo; Lopez, Ricardo Luis; Vigna, Mario Raul; Gigon, Ramon (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
Blanco, Anibal Manuel; Chantre Balacca, Guillermo Ruben; Lodovichi, Mariela Victoria; Bandoni, Jose Alberto; Lopez, Ricardo Luis; Vigna, Mario Raul; Gigon, Ramon; Sabbatini, Mario Ricardo (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
Lodovichi, Mariela Victoria; Blanco, Anibal Manuel; Chantre Balacca, Guillermo Ruben; Bandoni, Jose Alberto; Sabbatini, Mario Ricardo; Vigna, Mario Raul; Lopez, Ricardo Luis; Gigon, Ramon (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 ... -
Self‐regeneration of hairy vetch (Vicia villosa Roth) as affected by seedling density and soil tillage method in a semi‐arid agroecosystem
Renzi Pugni, Juan Pablo; Chantre Balacca, Guillermo Ruben; Cantamutto, Miguel Angel (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 ... -
Suppression of Lolium multiflorum Lam. with Vicia villosa Roth combined with residual herbicides
Renzi Pugni, Juan Pablo; Pérez Aagaard, Cristián; Chantre Balacca, Guillermo Ruben; Gigon, Ramon; Reinoso, Omar Juan; Quintana, Matias; Ducos, I.; Cantamutto, Miguel Angel (Ediciones INTA, 2022-04)Lolium multiflorum Lam. (annual ryegrass) is a problematic weed species especially in no-tillage systems of the southern region of Buenos Aires province (Argentina). Increasing herbicide resistance cases have exacerbated ... -
Towards an integrated weed management decision support system: A simulation model for weed-crop competition and control
Molinari, Franco A.; Blanco, Anibal Manuel; Vigna, Mario Raul; Chantre Balacca, Guillermo Ruben (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 ... -
