The study was done under greenhouse conditions at the Montecillo Campus of the Postgraduate College, Mexico. Two soils were used, one irrigated with sewage water and the other one with clean water from a well. Half of the plants were inoculated with Glomus intraradices. Metacaptan was used as a fungicide applied to half of the seeds. The pH of the soil was alkaline. Electric conductivity, and organic matter, nitric and ammoniac nitrogen, phosphorous, copper and nickel quantities were higher on the soils irrigated with sewage water. The soil contamination did not affect significantly plant responses in this study. It is concluded that endomycorrhiza inoculation (Glomus intraradices) gave better growth and yield, especially in beans. The application of fungicides improved plant growth.

It is also explained the world food crisis and its impact on the rise of food prices. Its effect on the profitability of wheat farmers. An analysis of the cost of production of the farmers and its competitiveness in presented, as well as recomendations to improve their profitability.

Esta coyuntura pro-pició un mejoramiento de la rentabilidad de los agricultores; sin embargo, se ha tenido una alta volatilidad en los precios del trigo. De manera simultánea, existe un aumento considerable en el precio de los insumos. Así, se presionan de nuevo las utilidades de los productores sonorenses y resulta imperativo tomar en cuenta las recomendaciones planteadas en este libro para el mejoramiento de la rentabilidad del cultivo del trigo en Sonora. Algunas de ellas están dirigidas a los productores, otras a los tomadores de decisiones. TRIGO EN SONORA Y SU CONTEXTO NACIONAL E INTERNACIONAL

Most participants (90%) had only basic formal education and no experience in agriculture. Both teachings were done simultaneously. Thus, they learn how to produce based on market demands, and how to operate as a business. This educational experience resulted in a high satisfaction for the participants, and gave them the skills needed for commercial production because they were able to produce and market one harvest. Their main challenge is to develop an enterprise.
