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 ... -

La siembra de cebolla sobre CC de vicia ... -
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. ... -
Environmental and agronomic determinants of hairy vetch (Vicia villosa Roth) seed yield in rainfed temperate agroecosystems
Renzi Pugni, Juan Pablo; Garayalde, Antonio Francisco; Brus, Jan; Pohankova, Tereza; Smýkal, Petr; Cantamutto, Miguel Angel (Elsevier, 2023-07)Vicia villosa Roth, commonly named hairy vetch (HV), is one of the most promising cover crop (CC) legumes, commonly included in strategies aimed at increasing agriculture sustainability. Due to the generally low yield, the ... -
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 ... -
Influencia del estado de madurez a cosecha sobre la calidad de semillas de alfalfa (Medicago sativa L.)
Renzi Pugni, Juan Pablo; Lasa, Juan Cruz; Cantamutto, Miguel Angel (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)La alfalfa (Medicago sativa L.) recién cosechada presenta dormición física debida a la dureza de sus tegumentos que puede afectar la producción de forraje en el primer año de implantación. Aunque se conoce que la temperatura ... -
Megachile rotundata (Fab.) as a potential agro-environmental conservation strategy for alfalfa seed production in Argentina
Renzi Pugni, Juan Pablo; Coito, Carlos; Reinoso, Omar Juan; Quintana, Matias; Garcia, Flavia Carina; Cantamutto, Miguel Angel (Wiley, 2021-11)Alfalfa (Medicago sativa L. 1753) is one of the main forage crops of the world, and the availability of an adequate seed supply to farmers is one of the main concerns for the seed industry. The international alfalfa seed ... -
Natural distribution and phenotypic traits of Neltuma flexuosa var. depressa, a candidate taxon for the rehabilitation in the central arid region of Argentina
Renzi Pugni, Juan Pablo; Reinoso, Omar Juan; Quintana, Matias; Cantamutto, Miguel Angel (Elsevier, 2023-02)Dryland rehabilitation in the central arid region of Argentina is urgently needed to reverse the current high levels of degradation. Neltuma flexuosa var. depressa, adapted to arid environments, gives it the potential to ... -
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.
