Se llevó a cabo un estudio de caso enmarcado en un proceso de investigación cualitativa, en torno a la Mesa de Desarrollo Rural de Laureles-Cañas, Tacuarembó. Para ello se utilizaron métodos cualitativos de investigación social como entrevistas abiertas estandarizadas y mapeo de actores sociales. La primera conclusión es que no existe una metodología pre-establecida para el trabajo en las MDR. Por otro lado, se identifica una visión enmarcada en el desarrollo rural con enfoque territorial. Otra de las conclusiones es que existen importantes actores del medio que no participan de las MDR, como las empresas forestales o los asalariados rurales. Asimismo, se dentificó la relevancia de los liderazgos locales y que existen ciertos problemas de representatividad de los delegados. Se establece un lineamiento sugerido de
trabajo en las MDR mediante capacitaciones, mapeos de actores y establecimiento claro del ámbito como tal. Abstract: A case study was carried out within a qualitative investigation process, concerning the Laureles-Cañas Rural Development Round Table (MDR), in Tacuarembó. Qualitative Methods of Social Investigation were used, such as open standardized interviews and mapping of social actors. The first conclusion arrived at is that there is no previously stated methodology in order to work with the MDRs. On the other hand, the Territorial Rural Development Scope was identified as the main vision implied in these Round Tables. Another conclusion arrived at was that there are relevant social actors that do not participate in these meetings, such as forestry companies or wage earners. Furthermore, local leaderships
were identified to be of relevant importance and it was also identified that there are certain representative issues. It is suggested that these MDR should use training methodologies, mapping of social actors and the clarifying of the aim of these meetings.

Abstract:
Argentina grows the second-largest area of lucerne in the world. Despite its importance, a yield gap exists between potential and measured yields, but factors contributing to it are still unclear. This study aimed to identify management factors and research needs to reduce the lucerne yield gap to improve the livestock systems in this region. We used meteorological data coupled with lucerne crop modelling and measured yields from the National Lucerne Cultivar Evaluation Network (NLCEN) to quantify the lucerne yield gap in nine sites located within the Argentinian Pampas (between parallels 30?45°S and meridians 58?65°W) and three sites outside the Pampas. Specifically, we used the model developed by McCall & Bishop-Hurley (2003), adapted and calibrated for lucerne in Argentina by Berone et al. (2017) to estimate the potential yield (PY) for 12 locations (three irrigated and nine rainfed), and compared those results with measured yields from the NLCEN to calculate yield gaps. We found the average available photosynthetic active radiation (PAR) and temperatures were sufficient to achieve 21.5 ±?3.7 t dry matter (DM) ha?1 yr?1 under rainfed conditions (environments with mean annual rainfall from 400 to 1,200?mm). However, the average measured yield from the NLCEN was 16.8 ±?2.4 t DM ha?1 yr?1 (a 22% gap). Potential yields ranged between 10 and 25?t DM ha?1 yr?1 under rainfed conditions and between 25 and 39?t DM ha?1 yr?1 for irrigated crops. As latitude increased rainfed locations had lower yields, while irrigated locations had higher yields. Adding irrigation was predicted to increase yields to 35.4 ±?2.0 t DM ha?1 yr?1 (a 53% gap) in rainfed sites. For irrigated locations, the gap was smaller (27.3 ±?3.5 vs 32.4 ±?2.2 t DM ha?1 yr?1 for measured vs potential yield, respectively), and most likely linked to nutrient deficits. Also, current grazing management was estimated to achieve approximately 50% less grazing efficiency than optimal grazing management. Our results demonstrated that the livestock industry can potentially increase animal production under current environmental conditions. The four main adjustments to achieve this are increased use of irrigation, increased use of fertilisers, earlier commencement of grazing in spring and increased stocking rates. The costs of irrigation, fertilisers and grazing management are envisaged to be small compared with potential increases in incomes and thus profitability available to beef and dairy farmers using lucerne as a major feed source in Argentina.
