Sources of phenotypic variation of wood density and relationships with mean growth in two eucalyptus species in Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2021-09-17)Aims of the study: To describe the radial patterns of wood density, and to identify their main sources of variation, and the potential tradeoffs with mean tree growth, in two Eucalyptus species. Area of study: Mesopotamian ... -
Source–sink relationships during early crop development influence earliness of sugar accumulation in sugarcane
(Oxford University Press, 2019-10)In subtropical environments where sugarcane (Saccharum spp.) crops are frequently limited by the duration of the growth cycle, earliness in maturity is a key genotypic trait. Using the concept of source–sink relationships, ... -
South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning
(Wiley, 2022-12)Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns ... -
Sowing density rather than row spacing influences chia radiation use and yield
(Wiley, 2022-10)Chia (Salvia hispanica L.) production worldwide has been encouraged due to its high essential fatty acid content that is effective for reducing cardiovascular affections. However, few studies have assessed the sowing density ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Soybean fungal soil-borne diseases: a parameter for measuring the effect of agricultural intensification on soil health
(2014)The aim of this study was to investigate the influence of agricultural intensification on soil microbial diversity, chemical and physical parameters, and the decrease of the incidence of sudden death syndrome (Fusarium ... -
Soybean grain protein and oil differences between Argentine cropping areas: an on-farn sampling approach
(Donau Soja, 2023-09-21)Soybean (Glycine max (L.) Merr.) is the most important crop in Argentina. It grows in different types of environments along the national area, considering an ample latitudinal range (-21°S to -55°) and different crop ... -
Soybean Maturity Groups, Environments, and Their Interaction Define Mega-environments for Seed Composition in Argentina
(Wiley, 2006-10)Argentina is the largest soybean [Glycine max (L.) Merrill] meal and oil exporter in the world, with crops covering a 23° to 39° S latitude range, allowing the presence of genotypes from different maturity groups (MG). ... -
Soybean nitrogen sources and demand during the seed-filling period
(American Society of Agronomy, 2019-05)Soybean [Glycine max (L.) Merr.] seed N demand not met by biological N fixation is fulfilled by N remobilization from vegetative plant organs and N uptake from soil sources during the seed-filling period (SFP), herein ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Soybean yield and water productivity gaps associate with ENSO-dependent effects of fungicide, sowing date and maturity group
(Elsevier, 2024-04)Context: Soybean, the focus of this study, is the most widely sown crop and the main source of external income in Argentina. The reported soybean yield gap calculated as the difference between water-limited potential yield ... -
Soybean yield, protein content and oil quality in response to interaction of arbuscular mycorrhizal fungi and native microbial populations from mono- and rotation-cropped soils
(Elsevier, 2020-03-01)Two main soil management practices are generally used for soybean production: monoculture (MC) and croprotation (CR). These strategies have different impacts on soil microbial communities. Among them, arbuscularmycorrhizal ... -
Spatial and temporal patterns of herbaceous primary production in semi‐arid shrublands: a remote sensing approach
(2016-07)Questions: Can herbaceous above‐ground net primary production (ANPP) be estimated from remote sensing when woody and herbaceous plants are intermingled? How does herbaceous ANPP change in space and time in an ecosystem ... -
Spatial and temporal plant-to-plant variability effects on soybean yield
(2018-08)Plant density and row spacing are management practices that farmers use to maximize soybean (Glycine max (L.) Merr.) yield. Other canopy aspects related to seedling establishment like spatial (spacing among plants) and ... -
Spatial and temporal synchronicity in the phenological events of Prosopis flexuosa in the Central Monte Desert = Sincronización espacial y temporal de los eventos fenológicos de Prosopis flexuosa en el Desierto del Monte Central
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-06)Some desert plant species are capable of using underground water and are therefore independent of rainfall events. Species of the genus Prosopis are thought to be facultative phreatophytes, since they have deep and shallow ... -
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ... -
Spatial and temporal variation of primary production of Patagonian wet meadows
(Elsevier, 2010-10)In extra-Andean Patagonia, wet meadows contrast with the prevailing arid steppes, and present a gradient of water availability from the periphery to the center. The objectives of this paper are to describe the spatial and ... -
A spatial dataset of topsoil texture for the southern Argentine Pampas
(2018-03)We produced a 1-km spatial resolution dataset of soil texture for the southern Argentine Pampas. Variables related to climate have higher prediction performance for soil texture. The soil texture varies gradually becoming ... -
