Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
(Springer Nature, 2022)Cropping diversification with cover crop mixtures combined with low N fertilization represents an ecological alternative that may promote sustainability. Our objective was to evaluate changes on soil organic fractions and ... -
The Use of Detached Leaf Inoculation for Selecting Cercospora kikuchii Resistance in Soybean Genotypes
(The American Phytopathological Society (APS), 2021-11)Cercospora leaf blight (CLB) causes extensive losses in soybean production in worldwide, including major soybean-producing countries such as Argentina. Cercospora kikuchii, C. cf. sigesbeckiae, C. cf. flagellaris, and C. ... -
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
(Springer Nature, 2022-02)Maize is one of the most important cereals for both human and animal nutrition, and diseases that affect the crop pose a major threat to global food security. Breeders are racing against time to develop genotypes resistant ... -
Relative performance of cluster algorithms and validation indices in maize genome-wide structure patterns
(Springer Nature, 2021-09)A number of clustering algorithms are available to depict population genetic structure (PGS) with genomic data; however, there is no consensus on which methods are the best performing ones. We conducted a simulation study ... -
Yield determinants, root distribution and soil water uptake in maize (Zea mays) hybrids differing in canopy senescence under post-silking drought
(CSIRO Publishing, 2021-05)Delayed canopy senescence or ‘stay-green’ (SG) trait in maize (Zea mays L.) could improve drought tolerance. Two field trials comparing four to six maize hybrids with different senescence rate were carried out at Buenos ... -
Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
Junglerice (Echinochloa colonaL.) seedling emergence model as a tool to optimize pre-emergent herbicide application
(Italian Society for Agronomy, 2021-07)Junglerice (Echinochloa colona), one of the worst and most problematic weeds globally, causes significant economic losses due to yield loss and control cost increase. Taking into account that this weed emerges in approximately ... -
Analysis of molecular mobility in corn and quinoa flours through ¹H NMR and its relationship with water distribution, glass transition and enthalpy relaxation
(Elsevier, 2021-03)Solids-water interactions of corn and quinoa flours were evaluated through 1H NMR, DSC, and water sorption isotherms. Glass transition temperature (Tg), observed by DSC, was better distinguished through FID signals, and ... -
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ... -
Comportamiento dinámico del peso del huevo en gallinas camperas discriminadas por indicadores productivos a la madurez sexual
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2020-10-29)The effects on the dynamic pattern of egg weight of five traits at sexual maturity were characterized in Campero Casilda hens. When the first egg was laid, body weight, age (an indicator of sexual precocity), weight of ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
The herbage productivity of tall fescue in the Pampas region of Argentina is correlated to its ecological niche
(Wiley, 2016-09)Since its introduction in the 1950s, tall fescue has spread throughout the Pampas region of Argentina to become naturalized in much of this region. Its annual forage mass productivity shows significant differences among ... -
Caracterización de poblaciones nativas de maíz mediante análisis de procrustes generalizado y análisis factorial múltiple
