Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Modelling long-term effects of cropping intensification reveals increased water and radiation productivity in the South-eastern Pampas
(Elsevier, 2013-08)Wheat/soybean double crop provides a reliable platform for cropping intensification in many subtropical and temperate areas, even in those with a short growing season as the South-eastern Pampas of Argentina. However, the ... -
Modelling water productivity for ecological intensification of crop sequences in the Inner Argentinean Pampas
(Elsevier, 2021-09)The design of crop sequences based on ecological intensification (EI) may help to restore lost agroecosystem services and to increase resource use efficiency. Our aim was to evaluate, using a modelling approach, the impact ... -
Patterns of resource use efficiency in relation to intra-specific competition, size of the trees and resource availability in ponderosa pine
(Elsevier, 2014-01-15)Patterns of resource use efficiency (RUE) in relation to intra-specific competition, size of the trees and resource availability are under debate. Also, the relationship between RUE and growth efficiency (GE) seems to be ... -
Producción de forraje y eficiencia uso del agua en diferentes cultivares de verdeos de invierno en el SO Bonaerense = Forage production and water use efficiency in different cultivars of winter grazing crops, in the SW of Buenos Aires
(Asociación Argentina de Producción Animal, 2022-09)El objetivo del siguiente trabajo fue evaluar la producción de forraje y su eficiencia uso del agua (EUA) en diferentes cultivares de verdeos de invierno en el partido de Bahía Blanca. -
Rendimiento y calidad de un cultivo de avena (Avena sativa L. ), bajo distintas láminas de riego en el noroeste de Chubut (Argentina)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2014-10)En un cultivo de avena se evaluó el impacto de diferentes láminas de riego sobre la productividad (materia seca y grano) y calidad de forraje, aplicadas a partir del estado fenológico de espigazón. También se determinó ... -
Respuesta del tabaco al riego deficitario para dos fechas de trasplante
(Ediciones INTA, 2019-04)En Argentina la producción de tabaco Virginia se localiza en Jujuy y Salta, donde la reposición de agua al cultivo se realiza principalmente con riego gravitacional. La posibilidad de regar con mayor precisión y la poca ... -
Riegos de gravedad a riegos de presión (goteo) en producciones hortícolas del valle bonaerense del río Colorado, Argentina
(EEA Hilario Ascasubi, INTA, 2022-12)La escasa acumulación de nieve en la cordillera argentina durante los últimos trece años provocó la disminución de los caudales del río Colorado. Los pequeños y medianos productores hortícolas ubicados en el sur bonaerense, ... -
Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America
(2012-12)Trees drought responses could be developed in the short- or in the long-term, aiming at sustaining carbon fixation and water use efficiency (WUE). The objective of this study was to examine short- and long-term adjustments ... -
Syrah and Grenache (Vitis vinifera) revealed different strategies to cope with high temperature
(Australian Society of Viticulture and Oenology, 2022-03-02)Background and Aims: Global warming will threaten vineyard sustainability in warm and arid regions. Therefore, increasing water use efficiency (WUE) is essential for long-term viticulture sustainability. Nevertheless, ... -
The effect of water status on productive and flowering variables in young ‘Arbequina’ olive trees under limited irrigation water availability in a semiarid region of Chile
(Springer, 2018-12)The intense drought affecting olive production in Northern Chile underscores the need to research non-traditional irrigation strategies to obtain the best crop performance. Accordingly, this study aimed to obtain preliminary ... -
Variabilidad espacial de la co-limitación de agua y nitrógeno, efecto sobre la eficiencia de uso de agua y nitrógeno en maíz
(Facultad de Agronomía, Universidad de Buenos Aires, 2015-08)El rendimiento en grano del cultivo de maíz (Zea mays L.) se encuentra principalmente limitado por agua y nitrógeno (N), presentando la oferta de ambos recursos una importante variabilidad espacial y temporal. Debido a ... -
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 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 use of wheat, corn and sunflower in the semiarid pampas = Uso del agua por trigo, maíz y girasol en la región semiárida pampeana
(Asociación Argentina de la Ciencia del Suelo, 2017)Crop water use in semiarid environments allows designing management strategies to improve water use efficiency. Our objective was to estimate wheat (Triticum aestivum L.), maize (Zea mays L.) and sunflower (Helianthus ...
