This chain faces structural challenges that limit its consolidation in terms of competitiveness and equity. This research aims to analyze the beekeeping value chain in the departments of Adolfo Alsina, Conesa, and Pichi Mahuida to determine the levels of competitiveness and equity among its actors, evaluating the barriers that hinder sustainable development. To this end, a research design was implemented based on semi-structured interviews directed at key stakeholders within the chain, as well as a digital survey. Data collection was complemented by the analysis of secondary sources and the application of systemic analysis tools to identify the chain’s links and their interrelationships, based on the chain analysis framework by Van Der Heyden et al. (2006). The diagnosis revealed that the chain suffers from marked fragmentation and a lack of stable critical mass, which weakens the bargaining power of the primary link. It is concluded that territorial strengthening and the pursuit of shared value are necessary conditions to promote a sustainable and more equitable beekeeping activity. 2026-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13903 Título: Efecto de la suplementación proteica durante el pastoreo de remolacha forrajera en el crecimiento post-destete de terneras en recría en el Valle Inferior de Río Negro (VIRN) Autor(es): Arizcuren, Hernán Martín Abstract: - 2026-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13831 Título: Aplicación anticipada de herbicidas en dosis reducidas: efectos sobre la dinámica de comunidades de malezas Autor(es): Cruz, Anabella Marisel Abstract: - 2026-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13575 Título: Evaluación del funcionamiento físico-hídrico del suelo en sistemas ganaderos del Partido de Patagones Autor(es): Hernández, Héctor Javier Abstract: - 2025-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/12341 Título: Uso de bocashi en cultivo de papa (Solanum tuberosum L.) como herramienta de manejo del suelo en una chacra de producción agroecológica Autor(es): Gianello, Mirco Abstract: - 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/11893 Título: Producción comercial de césped en panes y/o rollos en el Valle Inferior de Río Negro Autor(es): Lippi, Julieta Agostina Abstract: - 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/11671 Título: Caracterización del Valle Inferior de Río Negro mediante una sistematización de información histórica y aportes desde Sistemas de Información Geográfica Autor(es): Sylvester, Ana Paula Abstract: - 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/11516 Título: Fenología y características agronómicas del pecan [carya illinoinensis (wangenh.) c.koch] en el Valle Inferior del río Negro Autor(es): Molina Carrizo, Nadia Guadalupe Abstract: - 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/9175 Título: Cultivo de porotos como fuente de proteína alternativa para la alimentación humana y animal Autor(es): Aramburú, Paula Manuela Abstract: - 2022-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/9173 Título: Evaluación de parámetros bioquímicos relacionados con la calidad maltera en 12 líneas comerciales de cebada cervecera (Hordeum vulgare) Autor(es): Martínez Díaz, María Eugenia Abstract: - 2022-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/9156 Título: Estimación de las necesidades hídricas del cultivo de tomate en el Valle Inferior de Río Negro Autor(es): Geri, Agustín Abstract: - 2022-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/9038 Título: Caracterización de la comunidad de malezas en el cultivo de cebolla en transición agroecológica bajo diferentes manejos de fertilización y desmalezado Autor(es): Juárez, Marcos David Abstract: - 2022-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/8995 Título: Estudio de nuevas herramientas de control de plagas de nogales con énfasis en Cydia pomonella en el Valle Inferior del Río Negro.

Given the limited information that precedes this work guide the research to the early stages of buckwheat growth under different laboratory-generated environmental conditions. Five trials were developed. Four of them are in the germination stage, where the response of the seed to temperature variation, saline and water stress, and planting depth were evaluated. The last trial was carried out at the seedling stage and the response of the crop to different irrigation frequencies was studied. When evaluating different types of stress in the initial stages of the crop, we sought to gather useful information for possible situations to be found in the VIRN. In it, there is variability of soils, it is feasible to find sites with salinity and, a weight to contain of a quality water resource, an efficient use of it is necessary. Among the most outstanding results we can include the cultivation presenting germination percentages in a temperature range between 15 and 35 ° C. The optimum germination was identified at 30 ° C. In relation to saline stress, as the concentration of sodium chloride in the germination medium increased, their capacity and germination energy decreased. Likewise, it is important to highlight the tolerance to saline stress observed since, germination percentages of up to 80% were found with concentrations of 0.25 M. With regard to water stress during germination, simulated with polyethylene glycol, a decrease in the percentage of germination was observed from water potentials below -0.5 Mpa. The planting depth was relevant in establishing the seedlings of a crop. For the type of soil used in this work, the depth of 2 cm was identified as the optimum for sowing this crop. In general, variables such as: plant height, length and root dry matter were reduced with increasing planting depth. In the seedling irrigation frequency test, it was observed that more time-spaced irrigation showed a tendency to reduce morphometric variables (height,root length, number of leaves and leaf area). Under the experimental conditions, an optimal period of 4 days between irrigations was identified. The information found in these experiments is considered relevant to achieve optimal crop establishment and even interpret the effect of environmental conditions on the first stages of growth. These results provide references at the local and experimental level where the lack of information related to the cultivation of buckwheat was evidenced. 2020-01-01T00:00:00Z
