Design/methodology/approach: Compilation and analysis of primary information sources, through interviews with producers and key informants who participate in the process of commercialization of products derived from moringa. In total, there were eight companies. To collect the information, the snowball chain sampling technique was used. Results: All moringa producing companies analyzed started activities less than 10 years ago. The owners of the companies are small and medium producers, with an average of 6.5 ha, characterized by an organic management and constant training. The main products offered in the Mexican market are: the crushed leaf, flour and capsules, whose main market is the national one. On the other hand, it was detected that the producers in the market do not interact among each other, which generates asymmetry of information. In addition, the real inventory of the total number of producers and moringa producing companies in Mexico is unknown, which limits the characterization of production and benefit. Limitations/implications: The producers are not so accessible in certain information; for example, regarding the sale prices of their products. Findings/conclusions: Moringa is a multipurpose tree with great potential, a database of producers is unknown. The products offered are organic and healthy products. However, more research is needed on the commercialization of moringa in Mexico.

Yield and dry biomass weight of roots, stems and leaves were reduced by increasing salinity stress, while fruit quality characteristics were improved, with the magnitude of the changes being genotype-dependent. The landrace 'Veracruz' produced the lowest yield, 1.06 t ha-1 under control conditions and 0.59 t ha-1 when treated with 90 mM NaCl, amounting to a 44% reduction that was, however, the lowest yield decrease among all genotypes tested. Paradoxically, 'Veracruz' was the only landrace displaying a reduction in the root/shoot ratio when exposed to high salinity, indicating more sensitivity to salinity as compared to the other landraces and the hybrid tested. 'Campeche' performed the poorest in response to salinity with the most pronounced yield reductions, recording 71.1%, 80.1% and 89.6% yield decreases when comparing plants exposed to 30, 60 and 90 mM to the control, respectively. Although at each salinity level the 'Veracruz' fruits showed the highest °Brix value as compared to the other landraces and the hybrid, 'Oaxaca' and 'Puebla' fruits had a greater increase in °Brix between the control and 90 mM NaCl (109.2% and 110.4%, respectively). With 90 mM NaCl, 'Oaxaca' fruits also registered the highest decrease in pH (6.1%) and the highest increase in total soluble sugars (106.7%) with respect to the control.

La creación de empresas se vuelve un tema de investigación importante. El objetivo de este trabajo es determinar las diferencias que existen entre la manera de crear las microempresas. El trabajo se desarrolló en la comunidad de Santa Bárbara Almoloya con 73 microempresarios. Mediante un cuestionario se levantó la información necesaria y se han podido formar cuatro grupos que se diferencian entre sí, tanto en capitales financiero, social y humano como en motivaciones. Se concluye que los objetivos y el capital financiero son los elementos indispensables para la creación de las microempresas, pero este último pierde su importancia si las personas tienen un nivel de capital social alto. Las implicaciones de este trabajo sirven para los interesados en la promoción del emprendimiento en el medio rural, como instituciones de microfinanzas (IMF), gobierno e investiga...

While these types of organizations have played an important role, not all of these organizations have survived over time. Using information from interviews with leaders of five longeval coffee producer cooperatives in the Huatusco coffee region, this study tries to identify factors that could explain the longevity and long-term sustainability of these organizations. Additionally, using information from these interviews, we evaluate challenges that could put at risk the long-term sustainability of these associations and strategies to overcome these challenges from the cooperative’s leadership perspective. Findings from this study suggest the motivations behind the creation of these producer associations that goes beyond accessing go...
