英语. This research intended to correct the lack of fit of the regression model for each experiment in order to obtain more precise estimations of fertilizer economical optimum doses. Experimental data from 107 responses of corn to fertilization were examined in the Plan Puebla region. Several regression models were tested in each experiment. In order to generate the EEG, the EOD of nitrogen, phosphorus and economical optimum instead of yield were used. Three general response functions of the EOD of N, P and economic optimum yield were estimated, which include soil, climate and management variables. With them is possible to estimate EOD of N and P.

Se uso informacion de 107 experimentos de fertilizacion de maiz de temporal la region del Plan Puebla. Se probaron modelos de regresion a cada experimento y para ecuacion empirica generalizada se usaron como variables dependientes las DOE de nitrogeno y fosforo y los rendimientos optimos economicos ROE en el lugar de los rendimientos por tratamientos. Se generaron 3 funciones generales de respuesta de las DOE de N y P y el ROE que incluyen variables de suelo, clima y manejo con las cuales es posible estimar DOE de estos factores.
