Contenido :  Abstract: Aim Identify key factors driving legume seedlings performance in saline-sodic soils. Methods Five plots were established in paired subhumid steppes with saline-sodic soils dominated by Distichlis spicata or Panicum coloratum. In each plot, Lotus tenuis was sown in autumn and individual plants were collected close to nurse plants (dominant species), and in open areas, at the end of the cold and warm seasons. Carbon and nutrient acquisition (through C and O isotopic composition and N and P content measurements) and plant symbiotic functioning (through N fixation by rhizobia and mycorrhizal colonization measurements) were determined. Results Biomass of legume grown close to a nurse plant was always higher than in open areas. This increase was higher close to P. coloratum and to D.spicatainthecoldandwarmseasons,respectively. In both cases, L. tenuis improved its nutrient acquisition and symbiosis functioning. N-acquisition and rhizobia efficiency increased in the most facilitated L.tenuis plants in the cold season while P-acquisition was greater in the warm season. Conclusions Grass-to-legume facilitation in sub-humid steppes with saline-sodic soils was detected in cold and warm seasons, differing between steppes in relationship with the vegetation growing rate and the establishment and functioning of legume-rhizobia-mycorrhiza symbioses.

Contenido :  ABSTRACT. As part of a process of democratization and political renewal in Uruguay, the Government of Uruguay rehabilitated its agricultural research organization to create the National Institute for Agricultural Research (Spanish acronym INIA) in 1989. A public nongovernmental organization, INIA introduced a novel way of strengthening agricultural research capacity in the country by creating the Agricultural Technology Development Fund (Spanish acronym FPTA). The fund helps finance agricultural research that non-INIA researchers carry out outside INIA. The fund has proved to be a very flexible mechanism for establishing links to national and international sources of knowledge. This Briefing Paper describes how INIA identifies and selects projects for FPTA funding, and how it manages the fund. It highlights some key lessons learned. One key factor contributing to the FPTA's success is that it has enjoyed strong political support from the whole agricultural sector. Another important factor has been the two-year limit on FPTA projects, which encourages researchers to focus on practical results. INIA has found the FPTA an excellent tool to establish strategic alliances with other agricultural research organizations and institutes in Uruguay and help coordinate their research efforts and to achieve a multiplier for its own research efforts. ISNAR therefore chose INIA's FPTA as a "benchmark" for other agricultural research organizations. A benchmark is an example of a particularl... Presentar Todo
