Natural distribution and phenotypic traits of Neltuma flexuosa var. depressa, a candidate taxon for the rehabilitation in the central arid region of Argentina
(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 ... -
Nutrient Release Dynamics in Argentinean Pampean Soils Amended with Composts under Laboratory Conditions
(MDPI, 2022-03)Composted manure is the greatest nitrogen (N) source in organic agriculture, where the use of chemical fertilizers, except the use of rock phosphate as P source, is not allowed. The aim of this study was to evaluate the ... -
Panorama de las producciones vegetales intensivas de alimentos saludables – “Proalim Km 0”, en tiempos de pandemia por la Covid-19 – Parte 2 Preferencias de la producción, agroindustria, comercialización y consumo de diversidad de hortalizas
(Asociación Argentina de Horticultura, 2020-12-21)Las producciones de origen vegetal de alimentos saludables (PVIAS), particularmente las frutas y hortalizas, constituyen un grupo de alimentos de gran interés por los beneficios de su consumo, dada la importancia que tienen ... -
Podredumbres bacterianas de cebolla en Argentina. Situación actual y perspectivas a mediano plazo
(Asociación Argentina de Fitopatólogos, 2019-06)El cultivo de cebolla en Argentina se ve afectado por aproximadamente 25 enfermedades de origen biótico de las cuales cinco se destacan por las importantes pérdidas económicas que ocasionan: mildiu (Peronospora destructor), ... -
Producción de forraje y densidad de plantas de alfalfa irrigada comparando distintas densidades de siembra
(Asociación Latinoamericana de Producción Animal, 2002)La alfalfa es la forrajera principal en el valle bonaerense del Río Colorado, Argentina. Sin embargo, se carece de datos locales sobre la densidad de siembra (den. smb.) que asegure elevada persistencia y producción del ... -
Quantifying Irrigated Winter Wheat LAI in Argentina Using Multiple Sentinel-1 Incidence Angles
(MDPI, 2022-11)Synthetic aperture radar (SAR) data provides an appealing opportunity for all-weather day or night Earth surface monitoring. The European constellation Sentinel-1 (S1) consisting of S1-A and S1-B satellites offers a suitable ... -
Retrieval of Evapotranspiration from Sentinel-2: Comparison of Vegetation Indices, Semi-Empirical Models and SNAP Biophysical Processor Approach
(MDPI, 2019-10)Remote sensing evapotranspiration estimation over agricultural areas is increasingly used for irrigation management during the crop growing cycle. Different methodologies based on remote sensing have emerged for the leaf ... -
Seasonal mapping of irrigated winter wheat traits in Argentina with a hybrid retrieval workflow using sentinel-2 imagery
(MDPI, 2022-09-10)Earth observation offers an unprecedented opportunity to monitor intensively cultivated areas providing key support to assess fertilizer needs and crop water uptake. Routinely, vegetation traits mapping can help farmers ... -
Self‐regeneration of hairy vetch (Vicia villosa Roth) as affected by seedling density and soil tillage method in a semi‐arid agroecosystem
(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 ... -
Spontaneous Gene Flow between Cultivated and Naturalized Vicia villosa Roth Populations Increases the Physical Dormancy Seed in a Semiarid Agroecosystem
(MDPI, 2021-05)Hairy vetch (Vicia villosa Roth) is the second most cultivated vetch worldwide being used as a forage and cover crop. As it is not domesticated, it displays several wild traits including seed dormancy. The physical seed ... -
