The organic market is growing at a steady pace of 20 percent annually; this farming method can bring several advantages to the consumers and also to the farmers. Among other things organic farming does not have to rely on access to external inputs such as fertilizer and pesticides because the farmers make use of their own resources. This not only represents a friendlier environment to the farmer or the land but also can be cheaper. The aim of this study is to find out the yield differential between three productions systems (organic, biofertilized and conventional) of guava crops in Zitacuaro, Michoacan, Mexico. The results indicated that the most profitable crop in terms of production costs and profits on Zitacuaro´s region is the biofertilized crop that takes up the sustainable practices combined with conventional practices in a lesser proportion. While organic and conventional crops shows a slide difference between them.
