(Asociación Argentina de Horticultura, 2021-04)A partir del primer caso de infección de COVID-19, el Estado Argentino implementó el 20 de marzo de 2020 el régimen de Aislamiento Social, Preventivo y Obligatorio (ASPO). Este aislamiento no incluía a los actores sociales ... -
Distribución radical en plantaciones de kiwi (Actinidia chinensis var. deliciosa) en el sudeste bonaerense y su implicancia en el manejo racional del riego
(Ediciones INTA, 2022-08)Actualmente, el 50% de la superficie implantada con kiwi en Argentina se concentra en el sudeste bonaerense. El cultivo es sensible al estrés hídrico y requiere altos niveles de agua, por lo que el riego es indispensable ... -
Distribución y protección física de la materia orgánica en un molisol del sudeste bonaerense: efecto de sistemas de cultivos
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2020-10)Los suelos del Sudeste Bonaerense (SEB) presentan textura franca y alto contenido de carbono (C) orgánico (CO) total (COT). Sin embargo, han sufrido una pérdida generalizada de COT y, consecuentemente, de su salud, atribuida ... -
Distribution of bovine alpha-herpesviruses and expression of toll-like receptors in the respiratory system of experimentally infected calves
(Elsevier, 2016-04)This study provides an initial analysis of the toll-like receptors (TLRs) that might be implicated in alpha-herpesvirus infection of the bovine respiratory system. A significant variation in the expression of TLR3 and TLRs ... -
Distribution of bovine herpesvirus type 1 in the nervous system of experimentally infected calves
(Elsevier, 2016-03)Bovine herpesvirus type 1 (BoHV-1) is responsible for respiratory and genital disease in cattle. BoHV-1 encephalitis is only occasionally reported. However, several cases of neurological disease have been recently attributed ... -
Diversity of Auchenorrhyncha (Hemiptera: Cicadellidae: Delphacidae) associated with Vicia villosa in southern Buenos Aires province, Argentina
(2014-06)Among the Hemiptera, the Auchenorrhyncha are well known owing to their phytosanitary relevance since the group includes pathogen vector species able to damage commercial crops. Vicia villosa Roth (Fabaceae) is a fodder ... -
Día Mundial del Suelo: ¿Un día para tomar conciencia?
(Estación Experimental Agropecuaria Balcarce, INTA, 2020-11)Nuestra región al igual que muchas otras de Argentina, presenta graves problemas de degradación de sus tierras lo cual está directamente relacionado a la disminución la capacidad productiva de los suelos. Este proceso ... -
Does forest management affect the magnitude and direction of the afforestation effect on soil methane fluxes? A meta-analysis
(Elsevier, 2022-03)Evidence suggests that tree plantations change soil methane (CH4) fluxes (magnitude and/or direction of the fluxes) compared to herbaceous land (i.e. afforestation effect) due to the effect of trees increasing methanotroph ... -
Does nitrogen fertilization rate, timing and splitting affect sunflower yield and grain quality?
(Wiley, 2023-02)Nitrogen (N) deficiency could have a negative effect on sunflower (Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, and frequency of N fertilization to improve ... -
Does the photo-thermal environment limit post-flowering maize growth?
(Elsevier, 2020-07-01)After canopy closure and in the absence of limitations by water or nutrient availability, crop growth rate (CGR) of maize (Zea mays L.) is ultimately constrained by the daily incident radiation and temperature of the ... -
Dosis óptima económica de fósforo en el cultivo de papa en el sudeste bonaerense
(2016-06)Asegurar una buena disponibilidad de fósforo (P) para el cultivo de papa, es tan importante como ajustar la estrategia de fertilización para producir el máximo rendimiento con la mayor eficiencia económica. El Avail, aditivo ... -
Dot-blot immunoassay for detection of tomato chlorosis virus and reaction of potato genotypes to virus infection
(Springer, 2021-03-10)Tomato chlorosis virus (ToCV) is a whitefly-transmitted crinivirus that causes yield losses, mainly in tomato (Solanum lycopersicum) and potato (S. tuberosum) crops. In this work, a polyclonal antiserum for detecting the ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
(Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -
Drying of soybean seeds and effect on protein quality and oil extraction efficiency by extruding-expelling process
(Escola Superior de Agricultura Luiz de Queiroz (Brasil), 2023)Soybean seeds (Glycine max) were dried under real scale conditions to different final moisture content (m.c.) (9.1, 9.7, 10.9 %, and control with 16.2 %) and processed through extruding-expelling. Results indicated that ... -
Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
(MDPI, 2018-11)The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ... -
