Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
(Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
(Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
Water and solar radiation productivity of double-crops in a humid temperate area
(Southern Cross Publishing, 2011-12)The intensification of agricultural systems including sequential double-crops provides a reliable platform to increase the water and solar radiation use in many humid temperate areas of South America, which are predominantly ... -
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 Deficit Effect on the Relationship between Temperature during the Seed Fill Period and Soybean Seed Oil and Protein Concentrations
(Crop Science Society of America, 2009-05-01)Since most soybean [Glycine max (L.) Merr.] seed is processed into meal and oil, there is a growing concern about environmental effects on soybean seed composition. The aim of this work was to investigate how water deficit ... -
Water Footprint in paddy rice systems. Its determination in theprovinces of Santa Fe and Entre Ríos, Argentina
(Elsevier, 2015-09)In the context of social responsibility and, of the directives aimed at an integral management of natural resources, the Water Footprint (WF) has been widely spread as an indicator that contributes to a safe and sustainable ... -
Water productivity and net profit of high-density olive orchards in San Juan, Argentina
(Elsevier, 2021-04-08)Olive cultivation in Argentina has experienced an important expansion based on large-scale development of high density (HD) olive orchards. Intensification has led to yield increases, but, because of the high annual ETo ... -
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 ... -
Water relations, biochemical – physiological and yield responses of olive trees (Olea europaea L. cvs. Arbequina and Manzanilla) under drought stress during the pre-flowering and flowering period
(Elsevier, 2013-07)In arid and semiarid regions from Argentina, where the main olive production areas are located, evapotranspiration is high and rainfall is minimal during winter and spring months, as compared with the Mediterranean region ... -
Water status of plants under strips management in shrub-grass steppe of Southern Patagonia
(IRC, 2011-04-02)In the province of Santa Cruz Junellia tridens shrublands cover 2,8 million ha. These cummunities grow on site with coarser textured soil are dominated by 60-70 cm tall shrubs. Water is the most important factor regulating ... -
Water table contribution to alfalfa water use in different environments of the Argentine Pampas
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2002)In the Argentine Pampas, although the water table is considered an important source of water supply for the alfalfa crop, it has not been previously quantified.The goal of this study was to estimate ... -
Water table depth affects persistence and productivity of alfalfa in Central Argentina
(Elsevier, 2019-04)Alfalfa (Medicago sativa L.) is one of the most sown perennial legumes in the world. Water table depth can be both an opportunity and a threat for this crop. In this study we analyzed 20 years of field experimental data ... -
Water use of wheat, corn and sunflower in the semiarid pampas = Uso del agua por trigo, maíz y girasol en la región semiárida pampeana
