The study aimed to verify the response of the application of foliar fertilizers based on potash, sulfur and molybdenum, with and without plaster in the soil, on the agronomic traits of corn crop. The experimental design was a randomized block in a factorial 5 x 2 with four replications. The sources of variation showed no significant effect. These results indicate that the plaster efficiency in the agronomic characteristics can be possibly found with more reaction time of this conditioner into the soil, this justifies the non-significant effect of plaster on this cycle. The application of foliar fertilizers provided no significant increase in any of the variables, with no nutrients, probably due to availability and sufficient quantity in the soil where the study was conducted.
