Water Availability and Row Spacing Effects on Nitrogen Use Efficiency in No-Till Maize
(Scholars Direct, 2022-06-08)Reduced row spacing has shown to increase nitrogen use efficiency (NUE) in no-till irrigated maize; however available information in rainfed conditions is scarce. The objective was to analyze row spacing effects on NUE ... -
Water consumption and preliminary crop coefficients of two Populus ×canadensis clones (‘I-214’ and ‘I-488’) grown at low planting density
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA España), 2021-04)Aim of study: The productivity of poplar plantations in Mediterranean climates might be reduced due to lower precipitations in a climate change scenario. Therefore, understanding the water consumption in these plantations ... -
Water productivity in soybean following a cover crop in a humid environment
(Elsevier, 2020-02-05)We evaluated the influence of the termination dates of a winter cover crop on (i) soil water availability during soybean (Glycine max L. (Merr)) growing season, (ii) soybean evapotranspiration (ET) and iii) water productivity ... -
Water regulation by grasslands: a global meta‐analysis
(Wiley Online Library, 2018-06-03)Grasslands have been modified and replaced worldwide and have affected water regulation ecosystem services. In order to support public policies attending to the consequences of different grassland modifications and ... -
What is meat in Argentina?
(2017-10)Due to its strong cultural significance, the term “meat” in Argentina has been historically associated with beef, despite its wider definition in the Argentine Food Code. Only by the end of the last century did other meats ... -
Wheat spike fertility : inheritance and relationship with spike yield components in early generations
(2015)In wheat, grain number is considered as the product of spike dry weight (SDW) and the number of grains per unit of SDW, that is an indicator of spike fertility (SF). The aim of this study was to determine the heritability ... -
Where are the males? The influence of bottom-up and top-down factors and sociability on the spatial distribution of a territorial ungulate
(Springer, 2022-01)The factors that regulate the abundance and distribution of wild herbivores are key components of a species’ ecology and include bottom-up and top-down mechanisms, as well as aspects related to social organization. In ... -
White muscle disease in three selenium deficient beef and dairy calves in Argentina and Uruguay
(Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2018-05)White muscle disease (WMD), nutritional myodegeneration or enzootic muscular dystrophy, is a nutritional condition associated with selenium and/or vitamin E deficiency in ruminants. These elements are constituents of the ... -
Widespread and major losses in multiple ecosystem services as a result of agricultural expansion in the Argentine Chaco
(Wiley, 2020-09-09)1.Where agriculture expands into tropical and subtropical forests, social–ecological impacts are typically strong. However, where and how frontier development impacts on ecosystem functioning and services is often unclear, ... -
Wild and cultivated potato species diversity, taxonomy, and conservation
(Springer, 2021-09-22)In the present chapter, we summarize the knowledge of wild and cultivated potato species, diversity, a taxonomic update including group concept classification and description, species valid names, and a complete synonymy, ... -
Wild potato genetic reserves in protected areas: prospection notes from Los Cardones National Park, Salta, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-12-09)Wild potato species (WPS) are vital genetic resources to improve the productivity and sustainability of the third most important food crop worldwide. Although in situ conservation of this germplasm has been considered the ... -
