摘要：In Durango State, Mexico, the production of beans is usually perforrned under adverse conditions including: use of expensive and polluting chemical fertilizers, agriculture lands poor in organic material and erratic rainfall conditions. AH this adversely affects the environment, the physical and economic returns and which expression is a low standard of living of farrners. To assist in improving these conditions and reduce environmental damage, this study was implemented with the aim of analyzing the economic feasibility of the use of mycorrhiza (Glomus intraradices) and chemical fertilizer on beans (Phaseolus vulgaris L.) under rainfed conditions, in the spring-summer seasons of 2008 and 2009. The transfer of technology was done by researchers of the National Institute of Forestry, Agricultural and Livestock Research (INIFAP) - Valle del Guadiaoa and production was in direct seeding with producers undertheir own productions system. The evaluation was carned out in the municipalities ofGuadalupe Victoria, Cuencame, Peñon Blanco and Panuco de Coronado ofthe Durango state, Mexico. In the economic evaluation the methodology known as "Partial Budget" of CIMMYT was used. The resulta indicate that mycorrhizal fertilization practices are recommended for rainfed bean producers because the benefits outweigb the costs incUlTedby doubling the rates ofretum.
