A cost-effective and customizable automated irrigation system for precise high-throughput phenotyping in drought stress studies
(2018-06-05)The development of high-yielding crops with drought tolerance is necessary to increase food, feed, fiber and fuel production. Methods that create similar environmental conditions for a large number of genotypes are essential ... -
Geoscience and remote sensing on horticulture as support for management and planning
(Open Access Pub, 2019)The importance of horticulture around the large cities, called green belt (GB), or proximity food production area is related to its contribution to the provision of food as well as its role on social, cultural and ecological ... -
Mapping and characterizing the Green Belt of Córdoba: land dynamics and the urban-rural transformation process
(Open Access Pub, 2019)In Córdoba, Argentina, the peri-urban horticulture is in conflict with industrial agriculture and urban development. This problem is partly due to urban expansion to rural areas occurred in the last years and to monoculture ... -
Understanding member characteristics and cooperative price effects: the case of the Argentinean dairy sector
(2019-06-10)Since the 1990s, Argentinean dairy-processing cooperatives have lost considerable amounts of members and market share. We analyse their current role by investigating the characteristics of farmers who continue delivering ... -
Retention and redistribution of biological legacies generate resource sinks in silvopastoral systems of Arid Chaco forests
(Springer, 2019-07-11)Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promoting ... -
El cuadro de pastoreo en los sistemas extensivos de Patagonia Sur: Percepción y manejo del pastoreo heterogéneo.
(Asociación Argentina de Ecología, 2019-08)La producción ganadera extensiva en la Patagonia Sur se realiza sobre cuadros de pastoreo de gran superficie, escasa receptividad animal y fragilidad ambiental elevada. El manejo histórico del pastoreo, desde fines del ... -
Chloris gayana Kunth under different defoliation regimes. Morphogenesis, sward structure and leaf area index
(2019-10-09)Subtropical pastures are an important alternative to increase forage yields to fulfil cattle nutritional requirements. Despite the increasing expansion of these pastures in the semiarid subtropical region of Argentina, ... -
Rentabilidad de la agricultura de precisión: estimación de márgenes netos del cultivo de maíz con dosis fijas y variables de insumos
(Asociación Argentina de Economía Agraria, 2019-10-20)En el mundo surgen continuamente nuevas y mejores tecnologías de agricultura de precisión; éstas son expuestas a diversos tipos de ensayos y pruebas para demostrar su impacto productivo, pero raras veces se evalúan desde ... -
