The role of nurse functional types in seedling recruitment dynamics of alternative states in rangelands.
(2017-02-16)In arid ecosystems, recruitment dynamics are limited by harsh environmental conditions and greatly depend on the net outcome of the balance between facilitation and competition. This outcome can change as a consequence of ... -
The use of nutritional blocks as a tool for grazing management in extensive sheep husbandry
(Asociación Argentina de Ecología, 2021-09-05)The improvement in grazing spatial distribution is an important goal for the efficient and sustainable management of rangelands. However, extensive livestock systems such as the Patagonian rangelands generally fails due ... -
Tocopherol content, peroxide value and sensory attributes in roasted peanuts during storage
(2010-06)The objective of this study was to determine changes in tocopherol content, peroxide value (PV) and sensory attributes from roasted peanuts during storage at 40 °C. There were no differences in tocopherol contents between ... -
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 ... -
Use of the CSM-CROPGRO-peanut model in Argentina to estimate optimal sowing date and crop water productivity under different soil water content
(Instituto PROS, 2022-10-11)Almost 99% of Argentine peanut production is localized in Córdoba province, mainly under a rainfed regime. In this region, rainfall fluctuations can lead to droughts of varying severity. The peanut optimum sowing date can ... -
Validación de un método de selección para rendimiento en alfalfa basado en la depresión por endocría
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2011)La rápida depresión por endocría en alfalfa obedece a la pérdida de interacciones alélicas intra-locus en plantas tri y tetra alélicas. Éstas podrían identificarse por una prueba de autofecundación y luego combinarse en ... -
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 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 ...
