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, ... -
Climate change expected to improve digestive rate and trigger range expansion in outbreaking locusts
(Wiley, 2022-07-01)Global climate change will probably exacerbate crop losses from insect pests, reducing agricultural production, and threatening food security. To predict where crop losses will occur, scientists have mainly used correlative ... -
Comparative analysis of Argentinian and European populations of Ramularia collo-cygni on barley
(Wiley, 2024-03-19)Ramularia collo-cygni (Rcc) is a major barley pathogen that causes yield and grain quality losses worldwide. The main sources of Rcc inoculum are the seed and asexual airborne spores. In Argentina, Rcc is considered to be ... -
Complementary irrigation and direct drilling have little effect on soil organic carbon content in semiarid Argentina
(Elsevier, 2013-11)Irrigation and tillage modify soil properties. The aim of the present study was to evaluate the simultaneous effect of complementary irrigation and zero tillage (ZT) on soil organic carbon (SOC). Two treatments (irrigated ... -

(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 ... -
Degradation influences equilibrium and non-equilibrium dynamics in rangelands: implications in resilience and stability
(Wiley, 2022-09)Question: Plant communities are structured by both equilibrium and non-equilibrium dynamics, which interact at different spatiotemporal scales. The influence of external factors on internal regulation processes might depend ... -
Development in Origanum ssp.: a simple phenological scale todetermine thermal time requirements to critical reproductive events
(2015-04-21)Origanum spp. is commercially important as a main aromatic herb. However, little eco-physiological information is available regarding plant development and its control by genotype and environmental factors. Here, we aimed ... -
Development of a Simple and Cheap Device for Peanut Peg Strength Measurements = Desenvolvimento de um Dispositivo Simples e Barato para Medições de Força de Peg de Amendoim = Desarrollo de un dispositivo simple y económico para medir la resistencia de las cajas de maní
(Instituto PROS, 2021-09-30)Peg strength is an important plant trait to avoid digging losses although it can vary due to agronomic practices and cultivar characteristics. This attribute is usually measured by exerting a mechanical force through an ... -
