Optimización económica como estrategia para mejorar la productividad y sostenibilidad de los sistemas de producción de mora, de la provincia de Bolívar.

Abstract

The objetive was to optimeze economically the blackberry production systems, from Bolívar province as a strategy to improve their productivity and sustainability. In Bolívar province, the production and commercialization of blackberry is a survival strategy for producers that can be categorized as small-scale farmers, who use traditional production practices and are engaged in the rudimentary postharbest process. In practices, production problems lead to decision making to maximize benefits or reduce costs considering a certain number of restrictions. For this purpose, information was used fron 90 survery carried out in the province and information developed by the Instituto Nacional de Investigaciones Agropecuarias (INIAP), which served as the basis for applying this linear programming model. The results show that there are two types of blackberry producers that differ from each other, mainly by to surface, yields, net benefits and ways of marketing the blackberry. A maximization benefit of USD 4712.86 and USD 1776.08 per year was observed in the production systems of groups 1 and 2, respectively with the alternatives of INIAP, which are superior to conventional production systems. By varying the blackberry price per kilogram of the original model from USD 0.92 to 1.15 in group 1 and from USD 0.87 to 1.09 in group 2, there were increases of 43% and 49% in the net benefits, respectively. The results suggest that the blackberry production in the two groups of determined producers, using technologies generated by the INIAP, they are economically viable and sustainable alternatives to improve the producers´ incomes so it is recommended to implement them in the field.
