Using the Field Schools methodology, research was conducted to determine the financial efficiency of the integrated lemon management system (MIL) in semi-arid semi-warm climate (BS1hw), which allows higher income from productive activity of rural families compared to their initial situation. The work was carried out in Tlalcozotitlan, Copalillo, Guerrero, classified with a high index of poverty and lack of access to food. The diagnosis of the initial situation was obtained with the application of 30 questionnaires and the profitability of traditional technology was calculated, as well as a survey at the end of the study. School plots were established to evaluate the MIL system and modified integrated management (MIL-M), with recommendations, monitoring, evaluation and control of innovations made by the producer. The variables evaluated were degree of adoption of innovations, yield, production costs, income and B/C ratio. The results indicate a base yield of 2 t ha-1 with a production cost of $3 650 ha-1, gross income of $14 285.71 ha-1, with a B/C coefficient of 3.91. The MIL and MIL-M system obtained yields of 11.55 and 7.37 t ha-1, with production costs of $16 927.7 and $14 106.35 ha-1, gross income of $134 640.00 and $97 725.00, B/C coefficient of 7.95 and 6.93 respectively, which was associated with 88% degree of adoption of the innovations. The MIL system showed economic potential, offering farmers an opportunity to increase their income and making the activity more profitable.
