A research was carried out at Corpoica´s La Selva,Experiment Station located at Rionegro, Antioquia,Colombia, at 2.120 masl in the ecological zone Low Mountain Rain Forest. The objective was to characterize growth and development of andean blueberry Vaccinium meridionale Sw., plants, obtained by seed and clonal propagation, from a wild population of the species. Four plants of each type were transplanted to rizhotrons, ...

Agricultural research institutions have created technologies that aim to present alternative solutionsto the constraints of agricultural production through the generation of products and processes. However, in most cases, the adoption and impact of technology are unknown, presenting a constraint to the development of successful policies and technologies. This study analyzed the decision-making for soil management ...

Fruit crops in the northern of the Amazon region are found as part of the diversity in the farmer's chakras. The objective of the present study was to characterize the Amazonian fruits crops present in production farms of cocoa, coffee and silvopastoral systems located in the provinces of Orellana and Sucumbíos. The information was obtained on the basis of targeted surveys and direct observation in the field. The results ...

Soil deterioration in the Valle del Cesar has generated a gradual reduction of livestock in their productive response to pastures. That effect has been more intense in areas managed under a grass monoculture. As an alternative, an integration of agricultural, forest, and livestock production systems is proposed as an strategy for improving both environment preservation and production. The purpose of this study was to ...

Today, Mexico challenges a globalization trend where richer countries export basic products to developing countries, generating a food crisis that negatively affect the medium-small producers. For this reason, it is important to study the behavior of the food market (exports and imports), since the current Mexican development model does not achieve that food security be a national policy guaranteeing the provision of ...

The ethnobotanical uses of the medicinal plants in the Murocomba protected forest and its area of influence, located in the Valencia canton in Ecuador, were determined in this article; Fifty-six analytic types of surveys were applied in five locations. To obtain information on plant propagation, 20 surveys were carried out in forest localities. For the identification of the commercialization processes, 40 surveys were ...

Lulo blight is one of the most important problems of this crop in Colombia, present in all departments of the country that grow it, with an incidence of 100%. Due to the ignorance of the complexity of physiological races of Phytophthora infestans in cultivated lulo (Solanum quitoense), collections were evaluated from potato (Solanum tuberosum sub species andigena), tree tomato (Cyphomandra betacea) , tomato (Solanum ...

Las colinesterasas son un grupo de enzimas catalíticas, cuya actividad puede verse disminuida por diferentes factores, entre ellos la exposición a plaguicidas organofosforados. Mundialmente se reportan estos plaguicidas como los más utilizados en la producción de cultivos y, por lo tanto, quienes se exponen a través de sus labores a estas sustancias están en alto riesgo de sufrir efectos negativos sobre su salud. El ...

The purpose of this article is to identify market constraints in agricultural products between the various actors in the production and marketing chain. It starts with understanding the inequalities of opportunities for vulnerable communities, and events or traditions outside those communities, which generate the conditions that perpetuate poverty from generation to generation. Agents involved in this market are immersed ...

The objective was to determine the influence of storage time on the variation of texture and viscoelasticity of buns of corn of the white Cariaco variety. The samples were stored refrigerated at 15 °C during 15 days. Textural parameters were determined every two days, using a texture analyzer; viscoelastic properties were set by a test of relaxation and compression effort, adjusting the experimental data to the generalized ...
